First jQuery script, simple Form Focus, any problems?
<p>After studying the <a href="http://docs.jquery.com/Main%5FPage" rel="nofollow">docs</a> for a while, I came up with my first jQuery script. It's a simple Form Focus script. Just want to make sure I've got this right.</p>

<p>I couldn't find anything that spoke of "conditional statements" with jQuery, so I assume you just use standard JavaScript <code>if</code> / <code>else if</code> statments.</p>

<p>To test if the <code>#id</code> exists, the jQuery docs explained I should use <code>.length</code>.</p>

<pre><code>$(document).ready( function() {
    if ($('#one').length) {
     $('#one').focus();
    }
    else if ($('#two').length ) {
     $('#two').focus();
    }
    else {
     return false; // is this even necessary?
    }
});
</code></pre>

<p><strong>EDIT:</strong></p>

<p>It is possible that <code>#one</code> and <code>#two</code> will exist on the same page, so I want to target <code>#one</code> first.</p>
