****focus on text field when page loads using AJAX****

Hello all,

In our application we are using AJAX for our home page and all the related pages are included to it.

Its working fine. But i am unable to do focus on the first text field in the included pages as we do in normal form using onLoad & document.formname.elementname.focus funtion in body tag.

Here thre problem is- since it is included pages, we dont have body or form to set focus using above mentioned js function.

Is there any solution for this?
Could any one please tell me the solution for this problem as it is very important. Please reply

Thanks in advance,
