js: accessing scope of parent class

Question

I have a jquery class within a normal class in javascript. Is it possible to access variables in the scope of the parent class from a callback function in the jquery class?

Answer 1

You set "this" to a variable in the parent function and then use it in the inner function.

var simpleClass = function () {         
    this.status = "pending";     
    this.target = jqueryObject;     

    var parent = this;

    this.updateStatus = function() {         
            this.jqueryObject.fadeOut("fast",function () {            
                parent.status = "complete"; //this needs to update the parent class          
            });     
        }; 
    };
