Use jQuery to show/hide input based on another input's value
<p>I want to hide a specific input on a page unless a user types a Hotmail address into a different input. Whenever the user types in a hotmail address, I want to show the input. If the address is removed, I'd like it to disappear. How can this be accomplished with jQuery?</p>

<p>I know I'm going about this incorrectly, but here's what I have so far:</p>

<pre><code>$(function() {

 if($("select#combobox").val() *= '@hotmail') {

   $('#hotm').show();

 }

 else {

   $('#hotm').hide();

 }

 });
</code></pre>
