parent.frames.textFrame has no properties when app deployed on linux server

Hi,
I am new to javascript, can someone help to resolve the javascript issue:

I am trying code

outputString += '<a href="#" onclick="parent.frames[\'textFrame\'].funn(true);return false"><img alt="Close" align="right" src="'+CloseMenuIconSrc+'" border="0" width="16" height="16"/></a>';


This works fine in IE but for mozilla firefox giving error
- parent.frames.textFrame has no properties

this also works fine on windows, but it gives error when i deploy the same code on linux server

I have tried
window.top.frames['textFrame'].funn
parent.framename.funn(true);
But that does not work

Please help me,
Thanks in advance
