javascript anonymous function parameter passing

Question

I have some javascript code (within an object) :

toggle: function() {
    var me = this;
    var handler = function() { me.progress() };
    me.intervalId = setI         


        

Answer 1

You can use ".bind()":

var handler = function() { this.progress(); }.bind(this);

New browsers have "bind()", and the Mozilla docs have a solid implementation you can use to patch older browsers.
