Get all javascript variables in document

Question

Is there a way to retrieve all Javascript variables within a page?

For example, Firebug can view all of the JS vars, so I know it's possible, but I'm unsure on how to do it.

Answer 1

To get global variables:

var x=[];
for (var i in window){
    x.push(i)
};
alert(x.join("\\"));

They are stored in window object
