How can I mimic Greasemonkey/Firefox's unsafeWindow functionality in Chrome?

I'm just fiddling around with user scripts in chrome right now, so please bear with my potential ignorance/idiocy.

In the page I'm writing a script for, there is a <script> element that declares a variable x. Does this mean that, in my user script, I can just access x from the global namespace?

For example, if the only line in my userscript is alert(x);, should that work as expected (assuming x is a String)? I understand chrome doesn't support unsafewindow, but for some reason I'm finding it impossible to figure out how to mimic the functionality. Is it even possible?

Solution

  • contentWindow was available in Chrome 3, but removed in Chrome 4. Only possible solution for Chrome 4:

    location.href="javascript:(function(){ alert('Hello'); })()"
