<ul class="signatures"><li class="signature" id="hasClass-className">

<div class="longdesc">
<p>Elements may have more than one class assigned to them. In HTML, this is represented by separating the class names with a space:</p>
<pre><div id="mydiv" class="foo bar"></div></pre>
<p>The <code>.hasClass()</code> method will return <code>true</code> if the class is assigned to an element, even if other classes also are. For example, given the HTML above, the following will return <code>true</code>:</p>
<pre>$('#mydiv').hasClass('foo')</pre>
<p>As would:</p>
<pre>$('#mydiv').hasClass('bar')</pre>
<p>While this would return <code>false</code>:</p>
<pre>$('#mydiv').hasClass('quux')</pre>
</div>
<h3>Example:</h3>
<div class="entry-examples" id="entry-examples"><div id="example-0">
<h4><span class="desc">Looks for the paragraph that contains 'selected' as a class.</span></h4>
<pre class="prettyprint"><code class="example demo-code"><!DOCTYPE html>
