Extending class: set Scope when calling parent's methods

**warrean** · 6 Dec 2012 4:01 AM

Hey,

Why is the output of '1: ' not 'Parent'? How can I set the scope right?

I can't use method '2:' because then I don't have access to any of the Refs neither!

Code:

Ext.define('Parent', {
 extend: 'Ext.app.Controller',
 getName: function() {
     return Ext.getClassName(this);
 }
}

Code:

Ext.define('Child', {
    extend: 'Parent',
    doSomething: function() {
         console.log( '1: ' + this.getName() );
         console.log( '2: ' + this.superclass.getName() );
    }
}

This is how JavaScript works, the scope is the current scope which is the Child unless you change it with call or apply.

Code:

fn.call(scope, arg1, arg2);
fn.apply(scope, [arg1, arg2])
