Capture Mouse Coordinates to variable

164 100+
I hope this makes some sense. My ultimate goal here is to execute a block of code if the mouse has not moved in a minute or so within the broswer. The machine I am running this on is for internal use only, so I have no fear of this not working in certain browsers, etc.

I am no javascript pro but know enough to catch on if anyone is kind enough to help me out here. One of the only ways I could see this working is by having js check the mouse coordinates and compare them to see if they have changed or not. I dont know if this is an absurd way to go about or not, but I could see it working. So I have this so far, it just shows the x and y coordiantes...

I know the following is not correct at all, but I was just sketching the idea out in notepad for how the logic could work.

  1. counter = 0

  3. {
  4.   if tempxy == grabxy
  6.     set storexy cord
  7.     wait 5 seconds
  9.        if storexy == tempxy
  10.        counter = counter ++
  11. }
  13. else
  14. //code to go here
I dont even know if that is decipherable or even close to the correct syntax? But my MAIN question is this.. If someone can help me with this, I am pretty certain I can make this work.

How would I "capture" the tempX and tempY variables and store them in say, var Capture1 and then 5 seconds later "capture" tempX and tempY again, and store those values in say, var Capture2? If I can grab the coordinates at a given time I can then compare them. If the coordiantes stay the same for about 10 loops thorough that code, then my next block of code could be run.

... It is late.... I hope this makes sense, and I would be SUPER happy if someone could help me out, or at least point me somewhere.

Thanks a ton for any help!

Thanks for the reply! Your probably right, I may not need to capture the x-y coordinates, it was just the only thing I could come up with. I tired your code you posted, and it almost seems like it would work, and maybe I am missing something here. But when I try it out no matter if I move my mouse or not it launches the wake up alert. Am I missing something???

Thank you so much!

You got me- if it works at all, it should clear the timeout and set a new one on a mouse move or key press. I could guess if it did nothing...

Let me know if you figure it out- I can't make it fail, but I don't know your set up.

Maybe try setting the handlers on the window or the document instead of the body, or put a doctype on the page if it has none- I'm just guessing, but maybe it gets the method from the initial call and doesn't 'hear' the event from the body- you aren't handling mousemoves from anywhere else, are you?

It Works!

I have NO idea what was wrong earlier that had made it launch no matter what. I seriously cannot thank you enough. This was obviously a much better implementation than what I was trying to do.

Thanks again!!!
