[Javascript] writing to iframe

[John Huebner]

So you're saying it should be

window.frames.iframe_name.document.open();
window.frames.iframe_name.document.write("content to write");
window.frames.iframe_name.document.close();

However, I don't understand why it the script needs to write to the file 
on the server. I am trying to write to the iframe within the current 
document. The iframe starts out empty, no src value at all.

As I've said, It works in IE. IE seems to except it almost no matter how 
I write it. On the other hand, netscape does not. As I said. I can get 
netscape to write to the iframe the first time through but after that it 
fails.

I'm afraid you've lost me on with some of what you said.

I will try the above. Somehow I'm afraid that it is a problem with the 
Mozilla based browsers though.

If I have the above wrong please let me know,

As I said, I appreciate any input I can get on this.
