Setting focus on first input element

Setting focus on first input element

Hi All,

I am new to JS, Jquery, JSON and AJAX as well.

My problem is:
After submitting a form, I want to focus the first input element of my home page. I think I am able focus the element but not able to see cursor inside and also not able to write anything inside.
Below is the code I am using:
$(document).ready(function () {
                $("input[type='text']:first", document.forms[0]).focus();
            });

Can anyone help?

Thanks
