lazyResp is a jQuery plugin designed for responsive web layout that deals with responsive image delivery depending on screen width, with Retina and image lazy load support.
How to use it:
1. Load jQuery library and the jQuery lazyResp plugin in the document.
<script src="//code.jquery.com/jquery-1.11.1.min.js"></script> <script src="jquery.lazyresp.min.js"></script>
2. Insert an image into your document and use data-* attributes to specify the image sources for different screen widths.
<img src="480x360.jpg" height="250" width="250" class="lazyResp" data-small-retina="960x720.jpg" data-medium="1024x768.jpg" data-medium-retina="2048x1536.jpg" data-large="1920x1440.jpg" data-large-retina="2560x1920.jpg" >
3. Call the plugin on the image. The plugin will automatically swap out the src of the image depending on screen widths (breakpoints) defined in the plugin settings.
$(window).load( function() { $('img').lazyResp({ medium: 640, large: 1024, retina: 1.01, tolerance: 0, lazy: true, beforeLoad: function (img, preloaded) {}, afterLoad: function (img, preloaded) {} }); });
Change logs:
2014-12-13
- Added a new call to getRightImageSize when the plugin is called more than once on the same element and lazyload set to false
- Added a new call to both beforeLoad and afterLoad with a custom preloaded attr when the image has already been loaded
