How can I replace a class name using jQuery when I just know the start characters of the name?
<p>I have:</p>

<pre><code>&lt;tr id='id1' class='X-** other-class a-class'&gt; 
</code></pre>

<p>Where the * can be any number. </p>

<p>If I want to replace the class name that starts with X-99 then how can I do this? </p>
