What does this jquery code do?
<pre><code>$('[role="button"]').click(function () {
            myMethod();
        });
</code></pre>

<p>I know that on click on something it calls <code>myMethod()</code>, but on click on what?</p>

<p>What does <code>role</code> mean?</p>

<p>Is this button?</p>

<pre><code>&lt;input type="button" ... /&gt;
</code></pre>

<p>What is: <code>[role="button"]</code> ?</p>
