## Methods
|
||
|
||
#### ePub(bookPath, options)
|
||
|
||
Creates a new EPUBJS.Book()
|
||
|
||
bookPath is a optional convience method
|
||
that will start loading the book at that given path
|
||
```javascript
|
||
var Book = ePub("url/to/book/"); // With default options
|
||
```
|
||
|
||
```javascript
|
||
var Book = ePub({ restore: true });
|
||
Book.open("url/to/book/"); // Books can be opened later
|
||
```
|
||
|
||
Options:
|
||
|
||
```javascript
|
||
{
|
||
bookPath : null,
|
||
version: 1, // Changing will cause stored Book information to be reloaded
|
||
restore: false, // Skips parsing epub contents, loading from localstorage instead
|
||
storage: false, // true (auto) or false (none) | override: 'ram', 'websqldatabase', 'indexeddb', 'filesystem'
|
||
spreads: true, // Displays two columns
|
||
fixedLayout : false, //-- Will turn off pagination
|
||
styles : {}, // Styles to be applied to epub
|
||
width : false,
|
||
height: false,
|
||
}
|
||
|
||
```
|
||
|
||
Intially you'll probably just want to turn on restore.
|
||
|
||
The width and height will be set to the containing element's dimensions.
|
||
|
||
```javascript
|
||
var Book = ePub("url/to/book/", { restore: true });
|
||
```
|
||
|
||
The following examples will refer to this ePub variable as ```Book```.
|
||
|
||
#### Book.open(bookPath)
|
||
|
||
Will open and parse a book at the given path.
|
||
|
||
```javascript
|
||
var Book = ePub({ restore: true });
|
||
Book.open("url/to/book/"); // Books can be opened later
|
||
```
|
||
|
||
Books can be compressed epub.
|
||
See section X for additional information about handling these
|
||
|
||
```javascript
|
||
Book.open("url/to/book.epub");
|
||
```
|
||
|
||
|
||
#### Book.renderTo(element)
|
||
|
||
Appends the iframe that will contain the rendered book to a element.
|
||
|
||
Returns a promise with the render object after the first chapter has been loaded
|
||
|
||
```javascript
|
||
|
||
var Book = ePub("url/to/book/", { restore: true });
|
||
|
||
var $el = document.getElementById("div-id");
|
||
Book.renderTo($el);
|
||
```
|
||
|
||
renderTo can take a element id as a string.
|
||
|
||
```javascript
|
||
var Book = ePub("url/to/book/");
|
||
Book.renderTo("div-id");
|
||
```
|
||
|
||
#### Book.nextPage()
|
||
#### Book.prevPage()
|
||
|
||
Changes the page the book is on.
|
||
|
||
If on the first or last page of a chapter, the next chapter will be loaded.
|
||
|
||
```html
|
||
<div onclick="Book.prevPage();">‹</div>
|
||
<div onclick="Book.nextPage();">›</div>
|
||
```
|
||
|
||
if the book has not been rendered yet, page changes will have no effect.
|
||
|
||
#### Book.displayChapter(chap, end)
|
||
|
||
Loads book chapter at a given spine position or epub CFI string.
|
||
|
||
Returns a promise with the render after the given chapter has been loaded.
|
||
|
||
```javascript
|
||
Book.displayChapter('/6/4[chap01ref]!/4[body01]/10');
|
||
```
|
||
|
||
Setting End to true will advance to the last page of the chapter.
|
||
|
||
```javascript
|
||
Book.displayChapter(3, true);
|
||
```
|
||
|
||
#### Book.goto(url)
|
||
|
||
Loads book chapter that has the given url.
|
||
|
||
Returns a promise with the render after the given chapter has been loaded
|
||
|
||
```javascript
|
||
var skip = Book.goto("chapter_001.xhtml");
|
||
skip.then(function(){
|
||
console.log("On Chapter 1");
|
||
})
|
||
```
|
||
This is often used to create a table of contents, with links to specific chapters.
|
||
|
||
#### Book.setStyle(style, val, prefixed)
|
||
|
||

Book.setStyle("font-size", "1.2em");
|
||
```
|
||
|
||
#### Book.removeStyle(style)
|
||
|
||

|
||
|
||
#### Book.destroy()
