The jQuery and WordPress Plugins:

Methods

A method is a command you can use to control Infinite Scroll once the plugin has been initialized. You can call on any Infinite Scroll method by using $('.selector').infinitescroll('method-name');.

Bind
$('.selector').infinitescroll('bind');
Binds selector to check on scroll to see if the plugin needs to load more content.

Unbind
$('.selector').infinitescroll('unbind');
Unbinds selector to check on scroll to see if the plugin needs to load more content.

Destroy
$('.selector').infinitescroll('destroy');
Destroys the instance of infinite scroll. This is create a flag to not load anymore content and will unbind all events.

Pause
$('.selector').infinitescroll('pause');
Pausing the plugin will temporarily create a flag to not retrieve content on scroll. To unpause, use the method resume.

Resume
$('.selector').infinitescroll('resume');
Destroys the instance of infinite scroll. This is create a flag to not load anymore content and will unbind all events.

Toggle
$('.selector').infinitescroll('toggle');
Toggling will switch the pause value of the plugin, either pausing or resuming the plugin.

Retrieve
$('.selector').infinitescroll('retrieve');
Retrieve will load the next page of content if available.

Scroll
$('.selector').infinitescroll('scroll');
Scroll will check to see if the next page is to be loaded, the same thing as if a user scrolled.

Update
$('.selector').infinitescroll('update', {debug: true});
The update method is used to update options in the instance of Infinite Scroll after initialization. The second argument is the object of options that you want to update.

Options

Better documentation coming soon.

$('.selector').infinitescroll({
  loading: {
    finished: undefined,
    finishedMsg: "<em>Congratulations, you've reached the end of the internet.</em>",
                img: null,
    msg: null,
    msgText: "<em>Loading the next set of posts...</em>",
    selector: null,
    speed: 'fast',
    start: undefined
  },
  state: {
    isDuringAjax: false,
    isInvalidPage: false,
    isDestroyed: false,
    isDone: false, // For when it goes all the way through the archive.
    isPaused: false,
    currPage: 1
  },
  behavior: undefined,
  binder: $(window), // used to cache the selector for the element that will be scrolling
  nextSelector: "div.navigation a:first",
  navSelector: "div.navigation",
  contentSelector: null, // rename to pageFragment
  extraScrollPx: 150,
  itemSelector: "div.post",
  animate: false,
  pathParse: undefined,
  dataType: 'html',
  appendCallback: true,
  bufferPx: 40,
  errorCallback: function () { },
  infid: 0, //Instance ID
  pixelsFromNavToBottom: undefined,
  path: undefined, // Can either be an array of URL parts (e.g. ["/page/", "/"]) or a function that accepts the page number and returns a URL
  maxPage:undefined // to manually control maximum page (when maxPage is undefined, maximum page limitation is not work)
});

Examples

Scrolling inside an element

To scroll inside an element having overflow, use the local behavior.

$('.selector').infinitescroll({
  behavior: 'local',
  binder: $('.selector'), // scroll on this element rather than on the window
  // other options
});

Loading JSON data

As explained on the website, Infinite Scroll is designed for progressive enhancement, using existing pagination links. However, it is still possible to work with JSON data.

It means the nextSelector href will be called via AJAX, expecting JSON data, which will be passed to the callback function.

$('.selector').infinitescroll({
  // other options
  dataType: 'json',
  appendCallback: false
}, function(json, opts) {
  // Get current page
  var page = opts.state.currPage;
  // Do something with JSON data, create DOM elements, etc ..
});
