Version 2, June 1991

|

Copyright (C) 1989, 1991 Free Software Foundation, Inc., <http://fsf.org/>
|
||||||
|
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||||
|
Everyone is permitted to copy and distribute verbatim copies
|
||||||
|
of this license document, but changing it is not allowed.
|
||||||
|
|
||||||
|
Preamble
|
||||||
|
|
||||||
|
The licenses for most software are designed to take away your
|
||||||
|
freedom to share and change it. By contrast, the GNU General Public
|
||||||
|
License is intended to guarantee your freedom to share and change free
|
||||||
|
software--to make sure the software is free for all its users. This
|
||||||
|
General Public License applies to most of the Free Software
|
||||||
|
Foundation's software and to any other program whose authors commit to
|
||||||
|
using it. (Some other Free Software Foundation software is covered by
|
||||||
|
the GNU Lesser General Public License instead.) You can apply it to
|
||||||
|
your programs, too.
|
||||||
|
|
||||||
|
When we speak of free software, we are referring to freedom, not
|
||||||
|
price. Our General Public Licenses are designed to make sure that you
|
||||||
|
have the freedom to distribute copies of free software (and charge for
|
||||||
|
this service if you wish), that you receive source code or can get it
|
||||||
|
if you want it, that you can change the software or use pieces of it
|
||||||
|
in new free programs; and that you know you can do these things.
|
||||||
|
|
||||||
|
To protect your rights, we need to make restrictions that forbid
|
||||||
|
anyone to deny you these rights or to ask you to surrender the rights.
|
||||||
|
These restrictions translate to certain responsibilities for you if you
|
||||||
|
distribute copies of the software, or if you modify it.
|
||||||
|
|
||||||
|
For example, if you distribute copies of such a program, whether
|
||||||
|
gratis or for a fee, you must give the recipients all the rights that
|
||||||
|
you have. You must make sure that they, too, receive or can get the
|
||||||
|
source code. And you must show them these terms so they know their
|
||||||
|
rights.
|
||||||
|
|
||||||
|
We protect your rights with two steps: (1) copyright the software, and
|
||||||
|
(2) offer you this license which gives you legal permission to copy,
|
||||||
|
distribute and/or modify the software.
|
||||||
|
|
||||||
|
Also, for each author's protection and ours, we want to make certain
|
||||||
|
that everyone understands that there is no warranty for this free
|
||||||
|
software. If the software is modified by someone else and passed on, we
|
||||||
|
want its recipients to know that what they have is not the original, so
|
||||||
|
that any problems introduced by others will not reflect on the original
|
||||||
|
authors' reputations.
|
||||||
|
|
||||||
|
Finally, any free program is threatened constantly by software
|
||||||
|
patents. We wish to avoid the danger that redistributors of a free
|
||||||
|
program will individually obtain patent licenses, in effect making the
|
||||||
|
program proprietary. To prevent this, we have made it clear that any
|
||||||
|
patent must be licensed for everyone's free use or not licensed at all.
|
||||||
|
|
||||||
|
The precise terms and conditions for copying, distribution and
|
||||||
|
modification follow.
|
||||||
|
|
||||||
|
GNU GENERAL PUBLIC LICENSE
|
||||||
|
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||||
|
|
||||||
|
0. This License applies to any program or other work which contains
|
||||||
|
a notice placed by the copyright holder saying it may be distributed
|
||||||
|
under the terms of this General Public License. The "Program", below,
|
||||||
|
refers to any such program or work, and a "work based on the Program"
|
||||||
|
means either the Program or any derivative work under copyright law:
|
||||||
|
that is to say, a work containing the Program or a portion of it,
|
||||||
|
either verbatim or with modifications and/or translated into another
|
||||||
|
language. (Hereinafter, translation is included without limitation in
|
||||||
|
the term "modification".) Each licensee is addressed as "you".
|
||||||
|
|
||||||
|
Activities other than copying, distribution and modification are not
|
||||||
|
covered by this License; they are outside its scope. The act of
|
||||||
|
running the Program is not restricted, and the output from the Program
|
||||||
|
is covered only if its contents constitute a work based on the
|
||||||
|
Program (independent of having been made by running the Program).
|
||||||
|
Whether that is true depends on what the Program does.
|
||||||
|
|
||||||
|
1. You may copy and distribute verbatim copies of the Program's
|
||||||
|
source code as you receive it, in any medium, provided that you
|
||||||
|
conspicuously and appropriately publish on each copy an appropriate
|
||||||
|
copyright notice and disclaimer of warranty; keep intact all the
|
||||||
|
notices that refer to this License and to the absence of any warranty;
|
||||||
|
and give any other recipients of the Program a copy of this License
|
||||||
|
along with the Program.
|
||||||
|
|
||||||
|
You may charge a fee for the physical act of transferring a copy, and
|
||||||
|
you may at your option offer warranty protection in exchange for a fee.
|
||||||
|
|
||||||
|
2. You may modify your copy or copies of the Program or any portion
|
||||||
|
of it, thus forming a work based on the Program, and copy and
|
||||||
|
distribute such modifications or work under the terms of Section 1
|
||||||
|
above, provided that you also meet all of these conditions:
|
||||||
|
|
||||||
|
a) You must cause the modified files to carry prominent notices
|
||||||
|
stating that you changed the files and the date of any change.
|
||||||
|
|
||||||
|
b) You must cause any work that you distribute or publish, that in
|
||||||
|
whole or in part contains or is derived from the Program or any
|
||||||
|
part thereof, to be licensed as a whole at no charge to all third
|
||||||
|
parties under the terms of this License.
|
||||||
|
|
||||||
|
c) If the modified program normally reads commands interactively
|
||||||
|
when run, you must cause it, when started running for such
|
||||||
|
interactive use in the most ordinary way, to print or display an
|
||||||
|
announcement including an appropriate copyright notice and a
|
||||||
|
notice that there is no warranty (or else, saying that you provide
|
||||||
|
a warranty) and that users may redistribute the program under
|
||||||
|
these conditions, and telling the user how to view a copy of this
|
||||||
|
License. (Exception: if the Program itself is interactive but
|
||||||
|
does not normally print such an announcement, your work based on
|
||||||
|
the Program is not required to print an announcement.)
|
||||||
|
|
||||||
|
These requirements apply to the modified work as a whole. If
|
||||||
|
identifiable sections of that work are not derived from the Program,
|
||||||
|
and can be reasonably considered independent and separate works in
|
||||||
|
themselves, then this License, and its terms, do not apply to those
|
||||||
|
sections when you distribute them as separate works. But when you
|
||||||
|
distribute the same sections as part of a whole which is a work based
|
||||||
|
on the Program, the distribution of the whole must be on the terms of
|
||||||
|
this License, whose permissions for other licensees extend to the
|
||||||
|
entire whole, and thus to each and every part regardless of who wrote it.
|
||||||
|
|
||||||
|
Thus, it is not the intent of this section to claim rights or contest
|
||||||
|
your rights to work written entirely by you; rather, the intent is to
|
||||||
|
exercise the right to control the distribution of derivative or
|
||||||
|
collective works based on the Program.
|
||||||
|
|
||||||
|
In addition, mere aggregation of another work not based on the Program
|
||||||
|
with the Program (or with a work based on the Program) on a volume of
|
||||||
|
a storage or distribution medium does not bring the other work under
|
||||||
|
the scope of this License.
|
||||||
|
|
||||||
|
3. You may copy and distribute the Program (or a work based on it,
|
||||||
|
under Section 2) in object code or executable form under the terms of
|
||||||
|
Sections 1 and 2 above provided that you also do one of the following:
|
||||||
|
|
||||||
|
a) Accompany it with the complete corresponding machine-readable
|
||||||
|
source code, which must be distributed under the terms of Sections
|
||||||
|
1 and 2 above on a medium customarily used for software interchange; or,
|
||||||
|
|
||||||
|
b) Accompany it with a written offer, valid for at least three
|
||||||
|
years, to give any third party, for a charge no more than your
|
||||||
|
cost of physically performing source distribution, a complete
|
||||||
|
machine-readable copy of the corresponding source code, to be
|
||||||
|
distributed under the terms of Sections 1 and 2 above on a medium
|
||||||
|
customarily used for software interchange; or,
|
||||||
|
|
||||||
|
c) Accompany it with the information you received as to the offer
|
||||||
|
to distribute corresponding source code. (This alternative is
|
||||||
|
allowed only for noncommercial distribution and only if you
|
||||||
|
received the program in object code or executable form with such
|
||||||
|
an offer, in accord with Subsection b above.)
|
||||||
|
|
||||||
|
The source code for a work means the preferred form of the work for
|
||||||
|
making modifications to it. For an executable work, complete source
|
||||||
|
code means all the source code for all modules it contains, plus any
|
||||||
|
associated interface definition files, plus the scripts used to
|
||||||
|
control compilation and installation of the executable. However, as a
|
||||||
|
special exception, the source code distributed need not include
|
||||||
|
anything that is normally distributed (in either source or binary
|
||||||
|
form) with the major components (compiler, kernel, and so on) of the
|
||||||
|
operating system on which the executable runs, unless that component
|
||||||
|
itself accompanies the executable.
|
||||||
|
|
||||||
|
If distribution of executable or object code is made by offering
|
||||||
|
access to copy from a designated place, then offering equivalent
|
||||||
|
access to copy the source code from the same place counts as
|
||||||
|
distribution of the source code, even though third parties are not
|
||||||
|
compelled to copy the source along with the object code.
|
||||||
|
|
||||||
|
4. You may not copy, modify, sublicense, or distribute the Program
|
||||||
|
except as expressly provided under this License. Any attempt
|
||||||
|
otherwise to copy, modify, sublicense or distribute the Program is
|
||||||
|
void, and will automatically terminate your rights under this License.
|
||||||
|
However, parties who have received copies, or rights, from you under
|
||||||
|
this License will not have their licenses terminated so long as such
|
||||||
|
parties remain in full compliance.
|
||||||
|
|
||||||
|
5. You are not required to accept this License, since you have not
|
||||||
|
signed it. However, nothing else grants you permission to modify or
|
||||||
|
distribute the Program or its derivative works. These actions are
|
||||||
|
prohibited by law if you do not accept this License. Therefore, by
|
||||||
|
modifying or distributing the Program (or any work based on the
|
||||||
|
Program), you indicate your acceptance of this License to do so, and
|
||||||
|
all its terms and conditions for copying, distributing or modifying
|
||||||
|
the Program or works based on it.
|
||||||
|
|
||||||
|
6. Each time you redistribute the Program (or any work based on the
|
||||||
|
Program), the recipient automatically receives a license from the
|
||||||
|
original licensor to copy, distribute or modify the Program subject to
|
||||||
|
these terms and conditions. You may not impose any further
|
||||||
|
restrictions on the recipients' exercise of the rights granted herein.
|
||||||
|
You are not responsible for enforcing compliance by third parties to
|
||||||
|
this License.
|
||||||
|
|
||||||
|
7. If, as a consequence of a court judgment or allegation of patent
|
||||||
|
infringement or for any other reason (not limited to patent issues),
|
||||||
|
conditions are imposed on you (whether by court order, agreement or
|
||||||
|
otherwise) that contradict the conditions of this License, they do not
|
||||||
|
excuse you from the conditions of this License. If you cannot
|
||||||
|
distribute so as to satisfy simultaneously your obligations under this
|
||||||
|
License and any other pertinent obligations, then as a consequence you
|
||||||
|
may not distribute the Program at all. For example, if a patent
|
||||||
|
license would not permit royalty-free redistribution of the Program by
|
||||||
|
all those who receive copies directly or indirectly through you, then
|
||||||
|
the only way you could satisfy both it and this License would be to
|
||||||
|
refrain entirely from distribution of the Program.
|
||||||
|
|
||||||
|
If any portion of this section is held invalid or unenforceable under
|
||||||
|
any particular circumstance, the balance of the section is intended to
|
||||||
|
apply and the section as a whole is intended to apply in other
|
||||||
|
circumstances.
|
||||||
|
|
||||||
|
It is not the purpose of this section to induce you to infringe any
|
||||||
|
patents or other property right claims or to contest validity of any
|
||||||
|
such claims; this section has the sole purpose of protecting the
|
||||||
|
integrity of the free software distribution system, which is
|
||||||
|
implemented by public license practices. Many people have made
|
||||||
|
generous contributions to the wide range of software distributed
|
||||||
|
through that system in reliance on consistent application of that
|
||||||
|
system; it is up to the author/donor to decide if he or she is willing
|
||||||
|
to distribute software through any other system and a licensee cannot
|
||||||
|
impose that choice.
|
||||||
|
|
||||||
|
This section is intended to make thoroughly clear what is believed to
|
||||||
|
be a consequence of the rest of this License.
|
||||||
|
|
||||||
|
8. If the distribution and/or use of the Program is restricted in
|
||||||
|
certain countries either by patents or by copyrighted interfaces, the
|
||||||
|
original copyright holder who places the Program under this License
|
||||||
|
may add an explicit geographical distribution limitation excluding
|
||||||
|
those countries, so that distribution is permitted only in or among
|
||||||
|
countries not thus excluded. In such case, this License incorporates
|
||||||
|
the limitation as if written in the body of this License.
|
||||||
|
|
||||||
|
9. The Free Software Foundation may publish revised and/or new versions
|
||||||
|
of the General Public License from time to time. Such new versions will
|
||||||
|
be similar in spirit to the present version, but may differ in detail to
|
||||||
|
address new problems or concerns.
|
||||||
|
|
||||||
|
Each version is given a distinguishing version number. If the Program
|
||||||
|
specifies a version number of this License which applies to it and "any
|
||||||
|
later version", you have the option of following the terms and conditions
|
||||||
|
either of that version or of any later version published by the Free
|
||||||
|
Software Foundation. If the Program does not specify a version number of
|
||||||
|
this License, you may choose any version ever published by the Free Software
|
||||||
|
Foundation.
|
||||||
|
|
||||||
|
10. If you wish to incorporate parts of the Program into other free
|
||||||
|
programs whose distribution conditions are different, write to the author
|
||||||
|
to ask for permission. For software which is copyrighted by the Free
|
||||||
|
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||||
|
make exceptions for this. Our decision will be guided by the two goals
|
||||||
|
of preserving the free status of all derivatives of our free software and
|
||||||
|
of promoting the sharing and reuse of software generally.
|
||||||
|
|
||||||
|
NO WARRANTY
|
||||||
|
|
||||||
|
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||||
|
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||||
|
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||||
|
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||||
|
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||||
|
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||||
|
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||||
|
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||||
|
REPAIR OR CORRECTION.
|
||||||
|
|
||||||
|
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||||
|
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||||
|
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||||
|
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||||
|
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||||
|
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||||
|
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||||
|
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||||
|
POSSIBILITY OF SUCH DAMAGES.
|
||||||
|
|
||||||
|
END OF TERMS AND CONDITIONS
|
||||||
|
|
||||||
|
How to Apply These Terms to Your New Programs
|
||||||
|
|
||||||
|
If you develop a new program, and you want it to be of the greatest
|
||||||
|
possible use to the public, the best way to achieve this is to make it
|
||||||
|
free software which everyone can redistribute and change under these terms.
|
||||||
|
|
||||||
|
To do so, attach the following notices to the program. It is safest
|
||||||
|
to attach them to the start of each source file to most effectively
|
||||||
|
convey the exclusion of warranty; and each file should have at least
|
||||||
|
the "copyright" line and a pointer to where the full notice is found.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
Also add information on how to contact you by electronic and paper mail.
|
||||||
|
|
||||||
|
If the program is interactive, make it output a short notice like this
|
||||||
|
when it starts in an interactive mode:
|
||||||

|
Gnomovision version 69, Copyright (C) year name of author

This is free software, and you are welcome to redistribute it
|

under certain conditions; type `show c' for details.
|
||||||
|
|

|
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||||
|
parts of the General Public License. Of course, the commands you use may
|

be called something other than `show w' and `show c'; they could even be
|

mouse-clicks or menu items--whatever suits your program.
|

|
|

|
You should also get your employer (if you work as a programmer) or your
|
||||||
|
school, if any, to sign a "copyright disclaimer" for the program, if

|
necessary. Here is a sample; alter the names:

## About Lazy
|
||||||
|
Lazy is a fast, feature-rich and lightweight delayed content loading plugin for jQuery and Zepto.
|
||||||
|
It's designed to speed up page loading times and decrease traffic to your users by only loading the content in view.
|
||||||
|
You can use Lazy in all vertical and horizontal scroll ways.
|
||||||
|
It supports images in `<img />` tags and backgrounds, supplied with css like `background-image`, by default.
|
||||||
|
On those elements Lazy can set an default image or a placeholder while loading and supports retina displays as well.
|
||||||
|
But Lazy is even able to load any other content you want by [plugins](#loader-plugins) and [custom loaders](#custom-content-loaders).
|
||||||
|
|
||||||
|
|
||||||
|
## Compatibility
|
||||||
|
Lazy will work with a wide range of browsers and support jQuery versions for years backwards and Zepto as alternative.
|
||||||
|
You can pick any version since jQuery 1.7.2 or Zepto 1.1.6 or greater.
|
||||||
|
There is no way to guarantee, that Lazy will work with all browsers, but all I've tested worked great so far.
|
||||||
|
If you find any problems in specific browsers, [please let me know](http://github.com/eisbehr-/jquery.lazy/issues).
|
||||||
|
|
||||||
|
**Tested in:** IE, Chrome (+ mobile), Firefox (+ mobile), Safari (+ mobile) and Android Browser.
|
||||||
|
|
||||||
|
|
||||||
|
## Documentation / Examples
|
||||||
|
For [documentation](http://jquery.eisbehr.de/lazy/#parameter), [examples](http://jquery.eisbehr.de/lazy/#examples) and other information take a look on the [project page](http://jquery.eisbehr.de/lazy/).
|
||||||
|
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
First of all, you will need a copy of [jQuery](http://jquery.com) or [Zepto](http://zeptojs.com) to use Lazy successfully on your project.
|
||||||
|
If you get this you can install Lazy by different ways.
|
||||||
|
Some examples below:
|
||||||
|
|
||||||
|
#### CDN
|
||||||
|
Lazy and all plugins are available over [cdnjs](http://cdnjs.com) and [jsDelivr](http://jsdelivr.com) CDN and can directly included to every page.
|
||||||
|
```HTML
|
||||||
|
<!-- jsDeliver -->
|
||||||
|
<script type="text/javascript" src="//cdn.jsdelivr.net/gh/eisbehr-/jquery.lazy@1.7.7/jquery.lazy.min.js"></script>
|
||||||
|
<script type="text/javascript" src="//cdn.jsdelivr.net/gh/eisbehr-/jquery.lazy@1.7.7/jquery.lazy.plugins.min.js"></script>
|
||||||
|
|
||||||
|
<!-- cdnjs -->
|
||||||
|
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jquery.lazy/1.7.7/jquery.lazy.min.js"></script>
|
||||||
|
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jquery.lazy/1.7.7/jquery.lazy.plugins.min.js"></script>
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Self-Hosted
|
||||||
|
[Download](https://github.com/eisbehr-/jquery.lazy/archive/master.zip) and save one of two available files to include Lazy to your page, either the [development](http://raw.githubusercontent.com/eisbehr-/jquery.lazy/master/jquery.lazy.js) or the [minified](http://raw.githubusercontent.com/eisbehr-/jquery.lazy/master/jquery.lazy.min.js) version.
|
||||||
|
```HTML
|
||||||
|
<script type="text/javascript" src="jquery.lazy.min.js"></script>
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Package Managers
|
||||||
|
Lazy is even available through [NPM](http://npmjs.org) and [Bower](http://bower.io).
|
||||||
|
Just use one of the following commands below:
|
||||||
|
|
||||||
|
[](https://nodei.co/npm/jquery-lazy/)
|
||||||
|
```sh
|
||||||
|
$ npm install jquery-lazy
|
||||||
|
$ bower install jquery-lazy
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
## Basic Usage
|
||||||
|
1.) The basic usage of Lazy ist pretty easy.
|
||||||
|
First of all you need to prepare all elements you want to lazy load.
|
||||||
|
By default add a `data-src` attribute to images containing the loadable image and/or a `data-loader` attribute to elements witch shall use a [plugin](#loader-plugins) or [custom loaders](#custom-content-loaders).
|
||||||
|
```HTML
|
||||||
|
<img class="lazy" data-src="path/to/image_to_load.jpg" src="" />
|
||||||
|
```
|
||||||
|
|
||||||
|
2.) Start using Lazy by calling it after page load.
|
||||||
|
You don't have to specify your elements exactly, but for better performance, or different options, load your elements over unique classes or any other selector.
|
||||||
|
```JS
|
||||||
|
$(function($) {
|
||||||
|
$("img.lazy").Lazy();
|
||||||
|
});
|
||||||
|
```
|
||||||
|
Take a look at the [documentation](http://jquery.eisbehr.de/lazy/) to get an idea what Lazy is capable of.
|
||||||
|
|
||||||
|
|
||||||
|
## Callbacks / Events
|
||||||
|
Lazy comes with a bunch of [callbacks and events](http://jquery.eisbehr.de/lazy/index.php?c=callback) you can assign to.
|
||||||
|
Just add them by initialization settings:
|
||||||
|
* `beforeLoad` - before item is about to be loaded
|
||||||
|
* `afterLoad` - after the item was loaded successfully
|
||||||
|
* `onError` - whenever an item could not be loaded
|
||||||
|
* `onFinishedAll` - after all items in instance was loaded or returned an error
|
||||||
|
|
||||||
|
|
||||||
|
## Instances and public Functions
|
||||||
|
Lazy supports multiple parallel instances.
|
||||||
|
Just initialize them with different selectors.
|
||||||
|
To access an instances public functions you can initialize them in an object oriented manner or grab the instance bind to every element by default:
|
||||||
|
```JS
|
||||||
|
// object oriented way
|
||||||
|
var instance = $("img.lazy").Lazy({chainable: false});
|
||||||
|
|
||||||
|
// grab from elements (only works well if you use same selectors)
|
||||||
|
$("img.lazy").Lazy();
|
||||||
|
var instance = $("img.lazy").data("plugin_lazy");
|
||||||
|
```
|
||||||
|
|
||||||
|
Every instance has some public available functions to control it's behavior.
|
||||||
|
There are currently six available:
|
||||||
|
```JS
|
||||||
|
instance.config(entryName[, newValue]); // get or set an configuration entry
|
||||||
|
instance.addItems(items); // add new items to current instance
|
||||||
|
instance.getItems(); // get all unhandled items left of current instance
|
||||||
|
instance.update([useThrottle]); // loads all elements in current viewport
|
||||||
|
instance.force(items); // force loading specific items, ignoring the viewport
|
||||||
|
instance.loadAll(); // loads all remaining available elements from this instance
|
||||||
|
instance.destroy(); // unbinds all events and stop execution directly
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
## Custom Content Loaders
|
||||||
|
With the custom loaders option there is a powerful solution to load every contents the Lazy way.
|
||||||
|
Lazy will handle everything, you just create a loading method witch got triggered whenever the element hits the visibility threshold.
|
||||||
|
It is still possible to load images and custom loaders in the same Lazy instance.
|
||||||
|
|
||||||
|
To use this just define a loader function inside the Lazy initialisation and pass the loader name to the `data-loader` attribute of the elements witch should be lazy loaded.
|
||||||
|
```HTML
|
||||||
|
<div class="lazy" data-loader="customLoaderName"></div>
|
||||||
|
<img class="lazy" data-src="path/to/image_to_load.jpg" src="" />
|
||||||
|
<div class="lazy" data-loader="customLoaderName"></div>
|
||||||
|
<div class="lazy" data-loader="asyncLoader"></div>
|
||||||
|
```
|
||||||
|
```JS
|
||||||
|
$(".lazy").Lazy({
|
||||||
|

## Loader Plugins
|
||||||
|
The loader plugins can extend the functionality of Lazy, like loading other elements and data.
|
||||||
|
It is basically the same as the [custom content loaders](#custom-content-loaders), with the difference, that plugins can extend all further instances globally at once permanently and let them handle specific elements like `<video>` by default, without `data-loader` attribute set.
|
||||||
|
With custom content loaders you have to initialize each instance on setup with the loader.
|
||||||
|
With plugins you only load the plugin file and you're done for all instances from now on.
|
||||||
|
|
||||||
|
For more information and examples, take a look at the [existing plugins](https://github.com/eisbehr-/jquery.lazy/tree/master/plugins) or the [readme.md](https://github.com/eisbehr-/jquery.lazy/tree/master/plugins/README.md) in there.
|
||||||
|

combined | *boolean* | *false* | With this parameter, Lazy will combine the event driven and delayed element loading.
|
||||||
|
**attributes** | | |

|
|
||||||
|
|
||||||
|
## Build and Validation
|
||||||
|
This project includes an automated build script using `gulp`.
|
||||||
|
To build your own versions of Lazy you need to [install it](#package-managers) via [npm](https://www.npmjs.com/package/jquery-lazy) first.
|
||||||
|
Afterwards you can use the following command in your console to automatically generate all productive files.
|
||||||
|
While building these files everything will be checked with `jshint` for validity too.
|
||||||
|
```sh
|
||||||
|
$ gulp build
|
||||||
|
```
|
||||||
|
|
||||||
|
### Available `gulp` Tasks:
|
||||||
|
|
||||||
|
Name | Description
|
||||||
|
-------------- | -----------
|
||||||
|
build | check & build everything
|
||||||
|
build-main | check & build main project file
|
||||||
|
build-plugins | check & build single plugin files
|
||||||
|
concat-plugins | build concatenated plugins file
|
||||||
|
validate | check all files with `jshint`
|
||||||
|
watch | watches all files to check & build everything on change
|
||||||
|
|
||||||

"description": "Lazy is a fast, feature-rich and lightweight delayed content loading plugin for jQuery and Zepto. It's designed to speed up page loading times and decrease traffic to your users by only loading the content in view. You can use Lazy in all vertical and horizontal scroll ways. It supports images in 'img' tags and backgrounds, supplied with css like 'background-image', by default. On those elements Lazy can set an default image or a placeholder while loading and supports retina displays as well. But Lazy is even able to load any other content you want by plugins and custom loaders.",

## Document Note
|
||||||
|
This is not the main readme file of this project.
|
||||||
|
Please go to the [project root](https://github.com/eisbehr-/jquery.lazy) and take a look in the [README.md](https://github.com/eisbehr-/jquery.lazy/blob/master/README.md) to learn more about the basics of Lazy.
|
||||||
|
|
||||||
|
|
||||||
|
## About Loader Plugins
|
||||||
|
The loader plugins for Lazy can be used whenever you want to extend the basic functionality by default or globally for many instances of Lazy.
|
||||||
|
Just add the plugins you want to use or a combined file, containing all plugins, to your page and all instances can use the plugins from now on.
|
||||||
|
```HTML
|
||||||
|
<!-- as single plugin files -->
|
||||||
|
<script type="text/javascript" src="jquery.lazy.min.js"></script>
|
||||||
|
<script type="text/javascript" src="plugins/jquery.lazy.ajax.min.js"></script>
|
||||||
|
<script type="text/javascript" src="plugins/jquery.lazy.av.min.js"></script>
|
||||||
|
<script type="text/javascript" src="plugins/jquery.lazy.iframe.min.js"></script>
|
||||||
|
<script type="text/javascript" src="plugins/jquery.lazy.noop.min.js"></script>
|
||||||
|
<script type="text/javascript" src="plugins/jquery.lazy.picture.min.js"></script>
|
||||||
|
<script type="text/javascript" src="plugins/jquery.lazy.script.min.js"></script>
|
||||||
|
<script type="text/javascript" src="plugins/jquery.lazy.vimeo.min.js"></script>
|
||||||
|
<script type="text/javascript" src="plugins/jquery.lazy.youtube.min.js"></script>
|
||||||
|
|
||||||
|
<!-- or combined in one file -->
|
||||||
|
<script type="text/javascript" src="jquery.lazy.min.js"></script>
|
||||||
|
<script type="text/javascript" src="jquery.lazy.plugins.min.js"></script>
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
## Create an own Loader Plugin
|
||||||
|
If you want to, you can easily create own loader plugins.
|
||||||
|
Just use jQuery or Zepto's public function `Lazy` to create and register them.
|
||||||
|
Best practice is to wrap everything by an [IIFE](https://en.wikipedia.org/wiki/Immediately-invoked_function_expression).
|
||||||
|
```JS
|
||||||
|
(function($) {
|
||||||
|
$.Lazy("pluginName", function(element, response) {
|
||||||
|
// add your logic here
|
||||||
|
|
||||||
|
// 'this' is the current instance of Lazy
|
||||||
|
// so it's possible to access all public functions, like:
|
||||||
|
var imageBase = this.config("imageBase");
|
||||||
|
});
|
||||||
|
})(window.jQuery || window.Zepto);
|
||||||
|
```
|
||||||
|
|
||||||
|
This loader can now be called on every element with the attribute `data-loader` (_by default_), like:
|
||||||
|
```HTML
|
||||||
|
<div data-loader="pluginName"></div>
|
||||||
|
```
|
||||||
|
|
||||||
|
It's possible to register a plugin with more than one name / alias.
|
||||||
|
```JS
|
||||||
|
(function($) {
|
||||||
|
$.Lazy(["pluginName", "anotherPluginName"], function(element, response) {
|
||||||
|
// the plugin is now available by 'data-loader="pluginLoaderName"'
|
||||||
|
// and 'data-loader="anotherLoaderName"'
|
||||||
|
});
|
||||||
|
})(window.jQuery || window.Zepto);
|
||||||
|
```
|
||||||
|
|
||||||
|
The optional second parameter gives you the ability to register a plugin by default to an element type.
|
||||||
|
When you do this, there is no need to set the `data-loader` attribute on each element you want to use this loader on.
|
||||||
|
|
||||||
|
But keep in mind, if you register an plugin on often used elements, like `<div>`, Lazy will try to handle each of them!
|
||||||
|
If you want to do so anyway, use a most specific selector for jQuery or Zepto.
|
||||||
|
```JS
|
||||||
|
(function($) {
|
||||||
|
$.Lazy("av", ["audio", "video"], function(element, response) {
|
||||||
|
// this plugin will automatically handle '<audio>' and '<video>' elements,
|
||||||
|
// even when no 'data-loader' attribute was set on the elements
|
||||||
|
});
|
||||||
|
})(window.jQuery || window.Zepto);
|
||||||
|
```
|
||||||
|
|
||||||
|

||||||

|
||||||
|
## AJAX Loader
|
||||||
|
**Names:** `ajax`, `get`, `post`
|
||||||
|
**Parameters:** `data-src`, `data-method`, `data-type`
|
||||||
|
**Default for:** -
|
||||||
|
|
||||||
|
The AJAX loader can receive data from a given url and paste the response to the inner html of the element.
|
||||||
|
This is useful, when you want do load a bigger amount of content.
|
||||||
|
Use `ajax` as the loader name by default.
|
||||||
|
But there are even some shorthand names for specific request types `GET` and `POST` too.
|
||||||
|
```HTML
|
||||||
|
<!-- simple GET request -->
|
||||||
|
<div data-loader="ajax" data-src="ajax.html"></div>
|
||||||
|
|
||||||
|
<!-- simple post request with configurable response type -->
|
||||||
|
<div data-loader="ajax" data-src="ajax.html" data-method="post" data-type="html"></div>
|
||||||
|
|
||||||
|
<!-- GET request -->
|
||||||
|
<div data-loader="get" data-src="ajax.html"></div>
|
||||||
|
|
||||||
|
<!-- POST request-->
|
||||||
|
<div data-loader="post" data-src="ajax.html"></div>
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
## Audio / Video Loader
|
||||||
|
**Names:** `av`, `audio`, `video`
|
||||||
|
**Parameters:** `data-src`, `data-poster`
|
||||||
|
**Default for:** `<audio>`, `<video>`
|
||||||
|
|
||||||
|
Loads `<audio>` and `<video>` elements and attach the sources and tracks in the right order.
|
||||||
|
There are two ways you can prepare your audio and/or video tags.
|
||||||
|
First way is to add all sources by `data-src` attribute, separated by comma and type by pipe on the element.
|
||||||
|
```HTML
|
||||||
|
<audio data-src="file.ogg|audio/ogg,file.mp3|audio/mp3,file.wav|audio/wav"></audio>
|
||||||
|
<video data-src="file.ogv|video/ogv,file.mp4|video/mp4,file.webm|video/webm" data-poster="poster.jpg"></video>
|
||||||
|
```
|
||||||
|
|
||||||
|
The other way is to add the sources and tracks like default, as child elements.
|
||||||
|
```HTML
|
||||||
|
<audio>
|
||||||
|
<data-src src="file.ogg" type="audio/ogg"></data-src>
|
||||||
|
<data-src src="file.mp3" type="audio/mp3"></data-src>
|
||||||
|
<data-src src="file.wav" type="audio/wav"></data-src>
|
||||||
|
</audio>
|
||||||
|
|
||||||
|
<video data-poster="poster.jpg">
|
||||||
|
<data-src src="file.ogv" type="video/ogv"></data-src>
|
||||||
|
<data-src src="file.mp4" type="video/mp4"></data-src>
|
||||||
|
<data-src src="file.webm" type="video/webm"></data-src>
|
||||||
|
<data-track kind="captions" src="captions.vtt" srclang="en"></data-track>
|
||||||
|
<data-track kind="descriptions" src="descriptions.vtt" srclang="en"></data-track>
|
||||||
|
<data-track kind="subtitles" src="subtitles.vtt" srclang="de"></data-track>
|
||||||
|
</video>
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
## iFrame Loader
|
||||||
|
**Names:** `frame`, `iframe`
|
||||||
|
**Parameters:** `data-src`, `data-error-detect`
|
||||||
|
**Default for:** `<iframe>`
|
||||||
|
|
||||||
|
Loads `<iframe>` contents.
|
||||||
|
The default will return a successfull load, even if the iframe url is not reachable (_like on 404 or wrong url_), because there is no way to check the loaded content in javascript.
|
||||||
|
It might be the fastest and safest way to do that.
|
||||||
|
If you know the requested path is reachable every time or don't care about error checks, you should use this way!
|
||||||
|
```HTML
|
||||||
|
<iframe data-src="iframe.html"></iframe>
|
||||||
|
```
|
||||||
|
|
||||||
|
The second way is more professional and support error checks.
|
||||||
|
It will load the content by AJAX and checks the response.
|
||||||
|
Afterwards pass the HTML content to iframe inner and set the correct url.
|
||||||
|
This is a very secure check, but could be a bit more tricky on some use cases.
|
||||||
|
You should only use this on the same domain origin.
|
||||||
|
|
||||||
|
To enable this feature, set the attribute `data-error-detect` to `true` or `1` on the iframe element.
|
||||||
|
```HTML
|
||||||
|
<iframe data-loader="iframe" data-src="iframe.html" data-error-detect="true"></iframe>
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
## NOOP Loader
|
||||||
|
**Names:** `noop`, `noop-success`, `noop-error`
|
||||||
|
**Parameters:** -
|
||||||
|
**Default for:** -
|
||||||
|
|
||||||
|
The NOOP (_or no-operations_) loader will, like the name said, do nothing.
|
||||||
|
There will even be no callbacks triggered, like `beforeLoad` or `onError`, when using a NOOP` loader.
|
||||||
|
It could be useful for developers or to simple, secure and fast disable some other loaders.
|
||||||
|
It can be used with all elements.
|
||||||
|
```HTML
|
||||||
|
<div data-loader="noop"></div>
|
||||||
|
```
|
||||||
|
|
||||||
|
There are two other NOOP loaders, helping to debug your code.
|
||||||
|
The `noop-success` and `noop-error` loaders will return the current state to Lazy and trigger the right callbacks.
|
||||||
|
```HTML
|
||||||
|
<!-- triggers the 'afterLoad' and 'onFinishedAll' callback -->
|
||||||
|
<div data-loader="noop-success"></div>
|
||||||
|
|
||||||
|
<!-- triggers the 'onError' and 'onFinishedAll' callback -->
|
||||||
|
<div data-loader="noop-error"></div>
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
## Picture Loader
|
||||||
|
**Names:** `pic`, `picture`
|
||||||
|
**Parameters:** `data-src`, `data-srcset`, `data-media`, `data-sizes`
|
||||||
|
**Default for:** `<picture>`
|
||||||
|
|
||||||
|
Loads `<picture>` elements and attach the sources.
|
||||||
|
There are two ways you can prepare your picture tags.
|
||||||
|
First way is to create all child elements from a single line:
|
||||||
|
```HTML
|
||||||
|
<picture data-src="default.jpg" data-srcset="1x.jpg 1x, 2x.jpg 2x, 3x.jpg 3x" data-media="(min-width: 600px)" data-type="image/jpeg" />
|
||||||
|
```
|
||||||
|
|
||||||
|
The other way is to add the sources like default, as child elements.
|
||||||
|
```HTML
|
||||||
|
<picture>
|
||||||
|
<data-src srcset="1x.jpg 1x, 2x.jpg 2x, 3x.jpg 3x" media="(min-width: 600px)" type="image/jpeg"></data-src>
|
||||||
|
<data-img src="default.jpg"></data-img>
|
||||||
|
</picture>
|
||||||
|
|
||||||
|
<picture data-src="default.jpg">
|
||||||
|
<data-src srcset="1x.jpg 1x, 2x.jpg 2x, 3x.jpg 3x" media="(min-width: 600px)" type="image/jpeg"></data-src>
|
||||||
|
</picture>
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
## JS / Script Loader
|
||||||
|
**Names:** `js`, `javascript`, `script`
|
||||||
|
**Parameters:** `data-src`
|
||||||
|
**Default for:** `<script>`
|
||||||
|
|
||||||
|
Loads javascript files on `<script>` element.
|
||||||
|
Change the element like the example below, and the files will be loaded automatically after page load.
|
||||||
|
```HTML
|
||||||
|
<script data-src="script.js" type="text/javascript"></script>
|
||||||
|
```
|
||||||
|
|
||||||
|
**Note:**
|
||||||
|
The viewport detection is not correct in some browsers.
|
||||||
|
So it could happen, that all script files get loaded right after page load, and not when the user scrolls to them.
|
||||||
|
|
||||||
|
|
||||||
|
## Vimeo Video Loader
|
||||||
|
**Names:** `vimeo`
|
||||||
|
**Parameters:** `data-src`
|
||||||
|
**Default for:** -
|
||||||
|
|
||||||
|
Loads vimeo videos in an `<iframe>`.
|
||||||
|
This is the suggested way by vimeo itself.
|
||||||
|
You can prepare the `<iframe>` element as you would do without Lazy.
|
||||||
|
Only add the vimeo video id to the attribute `data-src` and add the loader name.
|
||||||
|
That's all.
|
||||||
|
```HTML
|
||||||
|
<iframe data-loader="vimeo" data-src="176894130" width="640" height="360" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
|
||||||
|
```
|
||||||
|
|
||||||
|
**Please keep in mind:**
|
||||||
|
Because this is an iframe and there is no feedback javascript could check on, this loader can only return success to Lazy.
|
||||||
|
There is no way to check if the video was loaded correctly or your provided video id is existing.
|
||||||
|
|
||||||
|
|
||||||
|
## YouTube Video Loader
|
||||||
|
**Names:** `yt`, `youtube`
|
||||||
|
**Parameters:** `data-src`
|
||||||
|
**Default for:** -
|
||||||
|
|
||||||
|
Loads youtube videos in an `<iframe>`.
|
||||||
|
This is the suggested way by youtube itself.
|
||||||
|
You can prepare the `<iframe>` element as you would do without Lazy.
|
||||||
|
Only add the youtube video id to the attribute `data-src` and add the loader name.
|
||||||
|
That's all.
|
||||||
|
```HTML
|
||||||
|
<iframe data-loader="youtube" data-src="1AYGnw6MwFM" width="560" height="315" frameborder="0"></iframe>
|
||||||
|
```
|
||||||
|
|
||||||
|
**Please keep in mind:**
|
||||||
|
Because this is an iframe and there is no feedback javascript could check on, this loader can only return success to Lazy.
|
||||||
|
There is no way to check if the video was loaded correctly or your provided video id is existing.
|
||||||
