Question

I would like to set the focus on the first element of the page using JQuery when the page is loaded. I could successfully set the focus for first element by using

Answer 1

You are calling on element that is not loaded in DOM. Place your code in ready function.

jQuery(document).ready(function() {
    $(":input:visible:first").focus();               
});

UPDATE:

As seen in @David answer and comments, he is right.

$(document).ready(function(){
    $("select:first").focus();
});

but you have not correctly included jquery (as seen in comment). you have missed to insert http before script src.

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>

Answer 2

The problem is most likely to be that you are not running the code on after the DOM is loaded. Try this one:

$(document).ready(function(){
   $("select:first").focus();
});

That should work.

EDIT: You can simplify the code a bit by using this:

$(function(){
  $("select:first").focus();
})

If you use it that way, jQuery will trigger that function when the document's DOM is ready.
