Get reference of window object from a dom element

Question

I have a javascript code like this

var element = $("elementId"); 

I got the reference to the element (which is a div).

Now I need to get the reference to the window in which this div element resides. But the problem is, here the $ is passed from a different window. So now the element resides in a different window.

How to get reference to that window object which contains this div element? Pls Help.

Answer 1

Get a reference to the DOM node, use the ownerDocument property to get a reference to the document, then read its defaultView property (parentWindow for IE8-) to get a reference to the window:

var $element = $('#elementId'); var element = $element[0]; // Assume that element exists, otherwise an error will be thrown at the next line var doc = element.ownerDocument; var win = doc.defaultView || doc.parentWindow;
