Hidden Frames

[Douglas Rowe]

I am trying to rid my application of all pop up windows and streamline transactions. Is there a recognized pattern or framework for using a hidden frame and recognizing state of the visible frame? I have several functions where I need to do two or three processes in sequence.

I'm not sure there's a pattern expressly for this purpose. Obviously, constantly looking up each and everything in the HTML DOM is too awkward for the apparent complexity you're dealing with.

When I recently had an app of similar complexity, I took the MVC pattern to the client side. My form state was pure Javascript, and each object in it had the ability to write itself into the HTML DOM, setting up event handlers as needed. The javascript object graph was model and controller, the HTML DOM was view.

You may want to get rid of the hidden frames and look into the XMLHttpRequest object since it is more reliable in that you know if a request is returned with or without an error. It is harder to do this with frames.
