IE Overwrite window.top

问题:

I'm trying to convince a page that it is the window.top even though it is in an iframe.

In FF you can do

window.defineGetter('top', function() { return window});

in Webkit (Safari/Chrome) you can simply do

window.top = window

but in IE none of those methods work. Anyone done this before?

回答1:

I'd maybe try using the "define getter" notation that John Resig uses in his article on the topic:

Window.prototype.__defineGetter__('top',function(){return this;});

回答2:

Try window.top = window.top.window

回答3:

Setting window.top doesn't work. Its not allowed in IE.

I ended up having to make my own fake window object, fill it with most of the properties of the window object, and then making a fake .top property.

回答4:

Use this:

Object.defineProperty(window, "parent", { 
        get: function() {return window;} 
    }
);
