JS Error in IE8

jayantb

I am getting "Object is Null or not an object" error in IE8 for document.getElementById().focus. Same is working fine in IE6.

Does anybody know about this error and how to handle it in IE 8?

Assuming you meant .focus() with parens. Might be working in IE6 by accident. Does it work in Firefox/firebug without error? Suggest you alert() the value of your element first, to make sure it's a non-null element that actually supports the focus() function. You can also check that
typeof(document.getElementById('helloworld').focus) == 'function'
returns true... though given your error message, I expect that getElementById() is actually returning null...

Hi,

I am trying to generate id by js. And it is being generated in all browsers except in IE7 and IE8. If you have any solution then please let me know.
