Jarmo Pertman commented on WTR-166:

I don't think you can do it easily with add_checker because every page behaves differently having different conditions to be met. I'd recomment using wait_until and similar things to play in here.

Jari made few nice additions to current Waiter.wait_until in his Watir-WebDriver project, which i'd like to incorporate into Watir (with minor changes) also. It's also ok by Jari.

Here are some examples:

Here is the code itself:

And then we could document using these methods.

What do you think?

If it's ok, i'll gonna do it soon.

> Watir.wait() listens to whether IE thinks its done loading, and then checks to see that the main document and any sub documents/frames have finished loading. More and more, there are pages that on load also kick off various XHRs and timers. For me - and possibly for a growing number of folks, testing more AJAXy applications - it would be great to expand wait() to check if there are any XHRs or timers pending, in additional to the checks it currently makes. 
> Note, I don't know, but there may be applications where an XHR is intentionally left open at all times. If this happens I would guess that it's rare, but if we change the default behavior of watir.wait() to wait for pending XHRs and timers, we might want to give a config option that turns this off as well.
