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 can mantain state using closure variables:

function simpleClass() {
   var _state = { status: "pending", target: jqueryObject; }

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

// Later...
var classInstance = new simpleClass();
