Easy JAIL for ExpressionEngine

ExpressionEngine Plugin to automate use of the jQuery Asynchronous Image Loader.

This fork keeps the content of the 'alt' attribute when images are replaced which is important if you want to have WCAG 2.0 compliant code.

The API

First off, this plugin requires jQuery. Using it requires 2 steps:

Step 1: Wrap the markup you want to JAIL in {exp:easy_jail:prep}

{exp:easy_jail:prep}
	{body}
{/exp:easy_jail:prep}

This will cause the plugin to convert

<img src="foo.png" alt=""/>

into

<img class="jail" src="data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==" data-src="foo.png" alt=""/>
<noscript><img src="foo.png" alt=""/></noscript>

Providing it with additional params allows you to customize certain bits:

• xhtml="n" - HTML output
• blank_img="my_blank.gif" - Your custom blank image
• class_name="custom_class" - Your custom class choice

Step 2: Include {exp:easy_jail:js} at the end of your body element, after you included jQuery.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="/j/jquery.js"><\/script>')</script>
{exp:easy_jail:js}

By default, this will include the JAIL script and a baseline configuration. To configure the output of the script, you can use the following parameters:

• class_name="custom_class" - Your custom class choice
• config="{offset:300}" - Your custom configuration (see the JAIL documentation for a run-down of options)
