jquery selectors (finding tag)
<p>I'm sure this is simple, but I can't seem to figure it out. I need to be able to pass a function an element id, and know what element tag it is.</p>

<p>For example:</p>

<pre><code>&lt;a id="first"&gt;&lt;/a&gt;
&lt;input id="last" /&gt;
</code></pre>

<p>If I know the id is "first", how can I get that the tag is "a"?</p>
