Usage

HTML

<div id="#you-want-lazyload">
  <!--
    Anything you want to lazyload
  -->
</div>

JavaScript

$('#you-want-lazyload').lazyload(options);

Options

threshold: Number (default: 0)

Sets the pixels to load earlier. Setting threshold to 200 causes image to load 200 pixels before it appears on viewport. It should be greater or equal zero.

load: Function(element) (default: undefined)

Sets the callback function when the load event is firing.

element: The content in lazyload tag will be returned as a jQuery object.

trigger: String (default: "appear")

Sets events to trigger lazyload. Default is customized event appear, it will trigger when element appear in screen. You could set other events including each one separated by a space, ex: mousedown touchstart.

Notice

You should initialize after the element add to page. Or it can't detect whether it's in screen. If you do that, you still can use $(window).trigger('scroll') to force detection.

Example

HTML

<div class=".lazyload">
  <!--
    <img src="image.png" />
  -->
</div>

JavaScript

$('.lazyload').lazyload({
  // Sets the pixels to load earlier. Setting threshold to 200 causes image to load 200 pixels
  // before it appears on viewport. It should be greater or equal zero.
  threshold: 200,

  // Sets the callback function when the load event is firing.
  // element: The content in lazyload tag will be returned as a jQuery object.
  load: function(element) {},

  // Sets events to trigger lazyload. Default is customized event `appear`, it will trigger when
  // element appear in screen. You could set other events including each one separated by a space.
