New Post: XMLHttpRequest, window and other Javascript objects

Hello,

I have not been able to get XMLHttpRequest nor "window" to work. For example:

window.open("http://www.example.com");

or

var xmlhttp = new XMLHttpRequest();

I know that I can implement my own XMLHttpRequest and window objects. My question is, if it is possible to use the standard native objects implemented in the V8 javascript motor and how?

Thank you!
