Calling method using JavaScript prototype

rated 0 times [ 30] [ 6] / answers: 1 / hits: 160977 / 16 Years ago, wed, february 18, 2009, 12:00:00

Is it possible to call the base method from a prototype method in JavaScript if it's been overridden?

MyClass = function(name){

    this.name = name;

    this.do = function() {

        //do somthing 

    }

};



MyClass.prototype.do = function() {  

    if (this.name === 'something') {

        //do something new

    } else {

        //CALL BASE METHOD

    }

};

I did not understand what exactly you're trying to do, but normally implementing object-specific behaviour is done along these lines:

function MyClass(name) {

    this.name = name;

}



MyClass.prototype.doStuff = function() {

    // generic behaviour

}



var myObj = new MyClass('foo');



var myObjSpecial = new MyClass('bar');

myObjSpecial.doStuff = function() {

    // do specialised stuff

    // how to call the generic implementation:

    MyClass.prototype.doStuff.call(this /*, args...*/);

}
