Trigger onmouseover event programmatically in JavaScript

Question

Is there a way to programmatically trigger the onmouseover event in plain JavaScript? or \"extract\" the method from the onmouseover event to call

Answer 1

I needed to do something similar, but I'm using jQuery, and I found this to be a better solution:

Use jQuery's trigger function.

$j('#top-div' ).trigger( 'mouseenter' );

You can also add parameters to it if you need to. See the jQuery documentation on .trigger.

Answer 2

You would do it something like this:

document.getElementById('top-div').onmouseover();

However, as mentioned in the comments, it would be worth testing before being considered an issue.
