<h1>Readmore.js</h1>
<p>A smooth, lightweight jQuery plugin for collapsing and expanding long blocks of text with “Read more” and “Close” links. </p>
</header>
<section id="info">
<p>The required markup for Readmore.js is extremely lightweight. No need for complicated sets of <code>divs</code> or hardcoded class names, just call <code>.readmore()</code> on the element containing your block of text and Readmore.js takes care of the rest. </p>
<p>Readmore.js is compatible with all versions of jQuery greater than 1.7.0.</p>
<h2 id="example">Example</h2>
<pre><code>$('article').readmore();</code></pre>
<p>Yes, it’s that simple. You can change the speed of the animation, the height of the collapsed block, and the open and close elements.</p>
<pre><code>$('article').readmore({
speed: 75,
maxHeight: 500
});</code></pre>
<h2 id="theoptions">The options:</h2>
<ul>
<li><code>speed: 100</code> (in milliseconds)</li>
<li><code>maxHeight: 200</code> (in pixels)</li>
<li><code>moreLink: '<a href="#">Read more</a>'</code></li>
<li><code>lessLink: '<a href="#">Close</a>'</code></li>
<li><code>embedCSS: true</code> (insert required CSS dynamically, set this to <code>false</code> if you include the necessary CSS in a stylesheet)</li>
<li><code>sectionCSS: 'display: block; width: 100%;'</code> (sets the styling of the blocks)</li>
<li><code>startOpen: false</code> (do not immediately truncate, start in the fully opened position)</li>
<li><code>beforeToggle: function() {}</code> (called after a more or less link is clicked, but <i>before</i> the block is collapsed or expanded)</li>
<li><code>afterToggle: function() {}</code> (called <i>after</i> the block is collapsed or expanded)</li>
</ul>
<p>If the element has a <code>max-height</code> CSS property, Readmore.js will use that value rather than the value of the <code>maxHeight</code> option.</p>
<h3 id="thecallbacks">The callbacks:</h3>
<p>The callback functions, <code>beforeToggle()</code> and <code>afterToggle</code>, both receive the same arguments: <code>trigger</code>, <code>element</code>, and <code>more</code>.</p>
<ul>
<li><code>trigger</code>: the "Read more" or "Close" element that was clicked</li>
<li><code>element</code>: the block that is being collapsed or expanded</li>
<li><code>more</code>: Boolean; <code>true</code> means the block is expanded</li>
</ul>
<h4 id="callbackexample">Callback example:</h4>
<p>Here's an example of how you could use the <code>afterToggle</code> callback to scroll back to the top of a block when the "Close" link is clicked.</p>
<pre><code>$('article').readmore({
afterToggle: function(trigger, element, more) {
if(! more) { // The "Close" link was clicked
$('html, body').animate( { scrollTop: element.offset().top }, {duration: 100 } );
}
}
});</code></pre>
<h3 id="recommendedcss">Recommended CSS:</h3>
<p>The intention behind Readmore.js is to use CSS for as much functionality as possible. In particular, “collapsing” is achieved by setting <code>overflow: hidden</code> on the containing block and changing the <code>height</code> property.</p>
<p>By default, Readmore.js inserts the following CSS:</p>
<pre><code class="css">.readmore-js-toggle, .readmore-js-section {
display: block;
width: 100%;
}
.readmore-js-section {
overflow: hidden;
}</code></pre>
<p>You can override the the first set of rules when you set up Readmore.js like so:</p>
<pre><code class="javascript">$('article').readmore({sectionCSS: 'display: inline-block; width: 50%;'});</code></pre>
<p>If you want to include the necessary styling in your site’s stylesheet, you can disable the dynamic embedding by passing <code>embedCSS: false</code> in the options hash.</p>
<pre><code class="javascript">$('article').readmore({embedCSS: false});</code></pre>
