I’ve been using domFunction() to determine whether it’s safe to do all of my DOM modification code, but with some testing, I noticed that some pages were causing Firefox to eat up huge amounts of CPU time. I tracked the error down to the domFunction call, as it uses setInterval() to run a function every n seconds. This in itself is nice to know (I was looking for a similar feature a couple of days ago), but the nice part is that it has a stopping function: clearInterval().
You are supposed to use it like this:
timer = setInterval("Function();", interval);
This will then call the function Function every interval milliseconds. Neato. Except I only want a particular thing to happen once. So, as a part of my code, I was calling clearInterval(timer) inside a function called by Function.
