button to start function which dynamicly chynges page

[BlueShadow]

Hi,
I have a function in my web2py app which takes quite a while. I like to have a button on a page which starts the funktion but does not reload the page for 10 minutes. The function should also dynamicly display its progress on the page. Is there a way to do that?

I would look at using ajax.  On the first call, use the scheduler to start the long computation,  and the call also sets a cookie, and activates a "busy" display that uses a timer to make the second call.  The second call sees the cookie, checks for results, displays what it can, and if not done repeats the busy/timer activation.

I'm interested in using this technique myself, but haven't quite got the js down to do the equivalent of $(document)ready(), but I'm hoping someone can fill in that gap.

thanks that will give me at least a starting point. Until you wrote I had no idea what I have to look at. I would be interested in your progress if you like to share

I've posted my single-pass ajax sample recently (20s per load), and the archives have several other people's examples, but I haven't got far in the multi-pass version yet.
