Returning *as* a script is in progress?

[Anidazen]

Hey guys.

 

I've never created an AJAX application, but I've looked at tutorials etc, and I think I understand the concepts.

 

The problem is, my script is designed to update piece-by-piece. This means not waiting for the called page to finish loading. How can I update as each different section of my script is ready? I can write any javascript, no problems -- do I need to use iframes or is there a clean way?

 

Thanks in advance.

 

 

 

Just to clarify... I would be fine doing this with an Iframe. I'd just pass arguments to the PHP in the URL, then write parent.function1("Values");

- or something similar.

 

What I don't understand is how to call functions in a similar way from the XMLRequest thingy that's used for cleaner AJAX -- without waiting for the entire page to load?
