jQuery: Is mouse over element?

Question

I could write something pretty easily to determine whether the mouse is over a given element, but is there already anything in the jQuery core library (or a plugin I guess) that will tell me whether the current mouse position is over a given element?

Answer 1

No.

You can use jQuery's hover event to keep track manually:

$(...).hover(
    function() { $.data(this, 'hover', true); },
    function() { $.data(this, 'hover', false); },
}).data('hover', false);

if ($(something).data('hover'))
    //Hovered!

Answer 2

You can use jQuery's mouseenter and mouseleave events. You can set a flag when the mouse enters the desired area and unset the flag when it leaves the area.
