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

Question

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?

Answer 1

Why do you need unsafeWindow? It's not a recommended practice, even in Greasemonkey/Firefox world.

Answer 2

contentWindow avalible in Chrome 3, but removed in Chrome 4. Only possible solution for Chrome 4:

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

Answer 3

ok heres an idea you can inject the script using the address bar...

javascript:var ElEm = document.createElement("script");ElEm.src='[path_to_script]';document.body.appendChild(ElEm);

then you can run whatever you want in the window with your javascript

@NV, Excellent ! Thanks.

@Carter Cole, how can you put javascript code instead of adding an url with the same aproach ?
