onMouseOut fix on nested elements – JavaScript

When you have nested elements and you add an onMouseOut event handler to the parent element, browsers trigger onMouseOut event when mouse pointer hovers it’s child elements.
While this is a standard behaviour, for one project I needed to write a code to override this behaviour.
With this code, when you mouse over the child elements, onMouseOut event will be ignored.

You can download this code here:

You can test it here:
http://images.code-head.com/code/javascript/fixOnMouseOuttest.html

This code is cross browser and here is how to use it:

<script language="javascript" type="text/javascript" src="fixOnMouseOut.js"> </script>
<div onMouseOut="fixOnMouseOut(this, event, 'JavaScript Code');">
   So many child elements
</div>

Hi,
I used this code, with a bit of tweeking, in making a fixed div grow and shrink as it should when the onmouseover and onmouseout events occur.
I had to use on both onmouseover and onmouseout events, otherwise the div would shrink and grow at will.
When the onmousover event occured I had to check what was the previous div that had the mouse over it, to see if the div should grow or not. I used a global variable for that.

Thank you, for the code, it’s been of great help.

Hello,

I saw this and it seemed like overkill, so I looked for something else.

It turns out that you can use onmouseenter and onmouseleave instead of onmouseover and onmouseout. Problem solved.

P.S I can’t see a single date except for “copyright 2011″ at the bottom, so I’m hoping this post isn’t 7 years old or something.

Hi Kyle, thanks for the comment, this post is 4 years old, this was one of my forum posts on my old forums that I got rid of around 2 years ago…

Hi,
Thank for your code. It is still helpful for browsers except for IE.

I changed your code just a little bit because I want to use a function rather than code text as dispatch routine.

1. function definition
function fixOnMouseOut(element, event, JavaScript_code)
=>
function fixOnMouseOut(element, event, eventHandler)

2. evaluate dispatch
eval(JavaScript_code);
=>
eventHandler(event);

It works well for me (Safari).
How can I treat your header comments?
