Checking if form already exists
<p>Is there a better command than this to check if a form is exists and if so submit it? Right now I'm using:</p>

<pre><code>if(document.forms[0])document.forms[0].submit()
</code></pre>

<p>Which works, however if form[0] does not exist it throws an exception. I'm trying to keep this dynamic in the sense I don't know what the form ID or name is.</p>
