i am trying to make something like google suggest. When you click on something in the iframe, that name must appear in the text Box
i have used that code to put stuff in the iframe.
but now, from an element in the frame i want to change a value outside the frame. but it gives this error

I wouldn't use an iframe for that, Ajax is the way to go.

i am using ajax to fill the iFrame

window.parent.document.getElementById('foo') if you'r trying to change something from the iframe.

when you type somthing in the textbox
now it says: uncaught exception: Permission denied to get property HTMLDocument.getElementById
Line 0
well??

you have a URL?

What is a good Ajax library to use?

i dont use any ajax library

in the list. has anyway else seen this problem before?
