jQuery: Focus on First Form Element

All in all, jQuery is pretty cool. I just stated working with it for a personal project and have found it simple and fairly intuitive to use, not to mention the plethora of available plug-ins.

I wanted to focus on the first input element in a form using jQuery. I haven't tested this extensively, but I came up with the following:

    $(document).ready(function() {
       // focus on the first text input field in the first field on the page
        $("input[type='text']:first", document.forms[0]).focus();
    });

We are simply using a selector to pick the first input element of type "text" in the first form on the page (that's the "document.forms[0]" stuff) and then focus on it. Of course, this is limited only to text fields, but could be extended to other types as well. I'd be interested in hearing about alternatives.
