Is it possible to disable, or even better, replace with a custom function, window.location?

This question is related: Disable a built-in function in javascript (alert)

While it works quite well for window.alert, this does not work for window.location.

We would love to be able to find a way to replace or disable (replace would be ideal, so we can AJAX log) window.location... Dirty advertisers have at times before used this to steal people away from our web properties.

Any ideas?

Even something that only works on a few specific browsers would be fine as once caught (via AJAX logging) we can act on this fairly quickly.

• javascript
• function
• replace
• built-in

• from chrome console: console.log(typeof window.location); object one step closer i suppose. any idea if what i am trying to accomplish is possible? – anonymous-one Commented Jun 25, 2011 at 15:30
• @anonymous-one: Nope -- it's a property, so you cannot replace it with your own code (there is no code to replace). – Jon Commented Jun 25, 2011 at 15:35
• Are you saying that advertisers are changing the window.location property in your web pages, and thus directing users away from your site to a different one? – bbg Commented Jun 25, 2011 at 15:35
• it has happened twice in the last 1.5 years (that we know of). we iframe all of our adspaces, but they were able to get around this via parent.window.location=....; – anonymous-one Commented Jun 25, 2011 at 15:39

try this

var _window = {
       location: "myLocation"
};

(function (window) {
   console.log(window.location);
}(_window));

I don't believe you can reassign window.location. From MDN:

Summary

Returns a Location object, which contains information about the URL of the document and provides methods for changing that URL. You can also assign to this property to load another URL.

https://developer.mozilla.org/en/DOM/window.location

As it takes a value like a property, how would you "reassign" the object/function to another value? I don't think it's possible due to the property behavior.
