Get element using getElementById on an Ajax processed page

[looloo2009]

Hello guys

Ive got an strange problem with my AJAX and javascript codes

I have a page default.asp initiates an ajax call to results.asp then content of this page which is in XML will be placed in a DIV on the default.asp page.
The main AJAX script is in a js file which is included in default.asp file. Standard Ajax stuff.
In the new contents of the DIV which is loaded from results.asp we have a new DIV which we load some other results from another page

This is the DIV in default.asp page which we load resutls from results.asp into that

<div id="first_ajax"></div>

This is the second DIV in results.asp page (exactly in that section which we called previously using AJAX call on default.asp) So this DIV is created using the first AJAX call and is loaded as a result into the above DIV

<div id="second_ajax"></div>

I have a link in the result of first page in the first DIV which is like this

<a href="javascript:doThisExternalFunction()">Click here</a>

which call a function from the external js file and load the result in the second DIV, I get result in that js file and load them into the DIV using

document.getElementById('second_ajax').innerHTML

everything is Okay and it works fine in IE , but the problem is that it doesn't work in FF or Opera, I get the error

document.getElementById('second_ajax') is null

It can't find the element in Ajax loaded page,
its strange coz It works fine in IE

Thanks in advance

Check if you are calling getElementById after creating the element, consider the rendering timestamp. And also if you are using frames, this can lead to "document" pointer complications. If you post the complete source, or the link to it, more help can be possible my friend.

Hello
Thanks a lot for ur reply

As I said before it is working in IE without any problem, doesn it make sense ?
I'll try to put the source here, its a little bit complicated coz its a small part of a big project
