Question

I have this:

function test1()
{
    this.count = 0;
    this.active = 0;
    this.enable = function () {this.active = 1;}
    this.disable = function () {this.active = 0;}
    this.dodo = function ()
                {
                    $("html").mousemove(function(event) {
                        // I want to get here the "active" param value;                 
                    });
                }
    this.enable();
    this.dodo();
}

instance = new test1();
instance.disable();

Let’s say I want to check the active param of the test1 class in the commented place. How can I get it there ?
Thanks!

If you want access to all the member variables of the higher scope, you just need to save the this pointer from that scope into a local variable so you can use it inside the other scope:

function test1() {
    this.count = 0;
    this.active = 0;
    this.enable = function () {this.active = 1;}
    this.disable = function () {this.active = 0;}
    var self = this;
    this.dodo = function () {
        $("html").mousemove(function(event) {
            // I want to get here the "active" param value;                 
            alert(self.active);
        });
    }
    this.enable();
    this.dodo();
}

instance = new test1();
instance.disable();
