Better way to call superclass method in ExtJS

Question

All the ExtJS documentation and examples I have read suggest calling superclass methods like this:

MyApp.MyPanel = Ext.extend(Ext.Panel, {
  initComponent: f         


        

Answer 1

I would simply change your code to:

var $cls = MyApp.MyPanel = Ext.extend(Ext.Panel, {
  initComponent: function() {
    // do something MyPanel specific here...
    $cls.superclass.initComponent.call(this);
  }
});

That way you only keep a single reference of your class name, now $cls. Only use $cls within your class methods and you'll be fine.
