I'm trying to create a JavaScript object that can be called to load a page
from a remote site. The page is behind SiteMinder security (and thus needs
to honor cookies) so I can't use the WinHTTP or MSXML objects (like I
thought I could).
The only browser support required is IE 6.
The code I have works: it generates a new iFrame, populates it with a form
and posts the form. My problem is in determining when the results are done
downloading.
I can access readyState on the iFrame, but I can't figure out how to keep
checking it for completeness without returning from the object method. (You
normally have to have several cooperating functions to check this - one sets
an timer to check and the other calls the first if the call isn't complete.)
However I want to do this in a single object (or function) that calls the
data and doesn't return until the data is available. A simple loop like:
while (iframe.readyState != "complete") {
};
This just pegs the CPU and crashes the container.
Any ideas on this?
