Question

I have an element with some child elements. When the mouse leaves the parent element I want to hide the parent and it’s children. Problem I’m having is that when I hover over any of the children, the mouseout event is being fired. What’s the best way to prevent this? I really only want the event to fire when the mouse is not within the parent or any of it’s children.

Answer 1

The event is bubbling up from the child to the parent (where it is being caught)

You should catch the event on the children by adding a listener and making the propagation stop there.

This code will stop the event from bubbling up to the parents handler

function onMouseLeave(e)
{
    if (!e) var e = window.event;
    e.cancelBubble = true;
    if (e.stopPropagation) e.stopPropagation();
}

question: The mouse off event is fired by the parent, when it should not. Mouseing over the child should not trigger a mouse off from the parent. How can we stop this?
