How do I get the Window object from the Document object?

Question

I can get window.document but how can I get document.window? I need to know how to do it in all browsers.

Answer 1

If you're going to be doing cross-browser Javascript, you should really look into one of the stable, well supported libraries. jQuery is my personal favorite.

This is just the first of many such questions you'll run into if you decide to "roll your own".

Answer 2

The document object does not have a window.

Answer 3

The Window object is the top level object in the JavaScript hierarchy, so just refer to it as window

Answer 4

You can go with document.defaultView if you want to exclude Microsoft browsers.

Answer 5

Well, this is the solution I went with. It works, but I hate it.

getScope : function(element) {
 var iframes = top.$$('iframe');
 var iframe = iframes.find(function(element, i) {
  return top[i.id] ? top[i.id].document == element.ownerDocument : false;
 }.bind(this, element));
 return iframe ? top[iframe.id] : top;
}
