Question

का उपयोग कर जावास्क्रिप्ट में कॉल बेस विधि मूल रूप से मैं नीचे इस पटर का उपयोग करके बेस विधि कैसे कॉल करूं?

var GS = {}; 
GS.baseClass = function (somedata) { 
    var that = {}; 
    that.data = somedata; 

    //Base class method 
    that.someMethod = function(somedata) { 
    alert(somedata); 
    }; 

    return that; 
}; 

GS.derivedClass = function(somedata) { 
var that = GS.baseClass(somedata); 

//Overwriting base method 
that.someMethod = function(somedata) { 
    //How do I call base method from here? 

    //do something else 
}; 
return that;

var GS = {}; 
GS.baseClass = function (somedata) { 
    var that = {}; 
    that.data = somedata; 

    //Base class method 
    that.someMethod = function(somedata) { 
    alert(somedata); 
    }; 

    return that; 
}; 

GS.derivedClass = function(somedata) { 
var that = GS.baseClass(somedata); 

//Overwriting base method 
var basemethod = that.someMethod; 
that.someMethod = function(somedata) { 
    //How do I call base method from here? 
    basemethod.apply(that, [somedata]); 
    //do something else 
}; 
return that; 
};
