Javascript mousetest
« on: April 01, 2012, 02:47:44 pm »
Well, I got this problem with javascript, I have to test if the mouse is over a element, but it must be in a if-condition.
Somehow this doesn't work: if (!document.getElementById('buttons').onmouseover)
Please help me!

if (!document.getElementById('buttons').onmouseover) tests if the onmouseover property of #buttons is defined, not whether it's triggered or not. Basically, it tests if the browser is going to do something when the user mouses over.

You could have onmouseover set a variable and onmouseout unset it.
Kind of like what was suggested here: http://www.sitepoint.com/forums/showthread.php?572033-Determine-if-mouse-is-over-an-element
I'll look around and see if there is a simpler way.

If you want to do a lot of tests I'm sure there is a way you can use this: http://www.permadi.com/tutorial/cssGetElementUnderMouse/index.html
