Perform action when browser toolbars change

I would like to be able to perform some action when adding or re开发者_如何学编程moving toolbars from the browser window. This should be done using Javascript. Any suggestions??

You can't know this. You can probably figure out, which i suspect you were hinting at was looking at the window resizing.

You can learn about it from this post: JavaScript window resize event

Please note that not all browsers might not call this with the change in toolbars.
