/** |
||||
* Usage: |
||||
* |
||||
* // using default options
|
||||
* $(document).endlessScroll(); |
||||
* |
||||
* // using some custom options
|
||||
* $(document).endlessScroll({ |
||||
* fireOnce: false, |
||||
* fireDelay: false, |
||||
* loader: "<div class=\"loading\"><div>", |
||||
* callback: function(){ |
||||
* alert("test"); |
||||
* } |
||||
* }); |
||||
* |
||||
* Configuration options: |
||||
* |
||||
* bottomPixels integer the number of pixels from the bottom of the page that triggers the event |
||||
* fireOnce boolean only fire once until the execution of the current event is completed |
||||
* fireDelay integer delay the subsequent firing, in milliseconds, 0 or false to disable delay |
||||
* loader string the HTML to be displayed during loading |
||||
* data string|function plain HTML data, can be either a string or a function that returns a string, |
||||
* when passed as a function it accepts one argument: fire sequence (the number |
||||
* of times the event triggered during the current page session) |
||||
* insertAfter string jQuery selector syntax: where to put the loader as well as the plain HTML data |
||||
* callback function callback function, accepts one argument: fire sequence (the number of times |
||||
* the event triggered during the current page session) |
||||
* resetCounter function resets the fire sequence counter if the function returns true, this function |
||||
* could also perform hook actions since it is applied at the start of the event |
||||
* ceaseFire function stops the event (no more endless scrolling) if the function returns true |
||||
* |
||||
* Usage tips: |
||||
* |
||||
* The plugin is more useful when used with the callback function, which can then make AJAX calls to retrieve content. |
||||
* The fire sequence argument (for the callback function) is useful for 'pagination'-like features. |
