Question

I have a setup of multi level backbone inheritance, but would like to call back of the previous super class. Not sure if is possible.

Scenario:

BasicView -> MediumView -> HardView

Where I would love that when HardView created, it will loops to call previous super class initialize function.

Example is here:

There are no implicit references to the superclass in standard JavaScript – you have to explicitly call the supertype’s methods

var Basic = Backbone.View.extend({
    initialize: function(){
        console.log('base');
    }        
});


var Medium = Basic.extend({
    initialize: function() {
        console.log(Basic.prototype.initialize.apply(this, arguments));
        console.log('medium');
    }        
});

var Hard = Medium.extend({
    initialize:function(){        
        console.log(Medium.prototype.initialize.apply(this, arguments));
        console.log('hard');
    }        
});


var hard = new Hard();
