title: Changing the selected option of an HTML Select element
body: <p>In my HTML, I have a <code>&lt;select&gt;</code> with three <code>&lt;option&gt;</code> elements.  I want to use jQuery to check each option's value against a Javascript <code>var</code>.  If one matches, I want to set the selected attribute of that option.  How would I do that?</p>
