Prototype : is a copy of the reference object
Step: 1 Create a website http://manas6/aspnet.35/mm.OOJavaScript7/
Step: 2 Codes
var doc = false; var x1=""; var x2="";
//function is an object in JavaScript, function with () is a constructor
// ( it is not comparable with with C# or Java
function myPetConstructor(b1, b2) {
doc.innerHTML += "<br/> Consturctor Fired";
this.x1 = b1; this.x2 = b2;
this.x1Return = function(x1) { if (this.x1 == b1) { return ("nice " + x1); } };
this.x2Return = function(x2) { if (this.x2 == b2) { return ("price " + x2); } };
}
// var pet1 = new myPetConstructor(this.x1,this.x2);
function start(a1, a2) {
doc.innerHTML += x1 + x2;
//propIn JavaScript when an object is created fom an existing object
//is a prototype of the reference object
//below pet2 is a prototype of object myPetConstructor
var pet2 = new myPetConstructor(a1, a2);
doc.innerHTML += "<br/> check prototype ! " + myPetConstructor.prototype.isPrototypeOf(pet2);
doc.innerHTML += "<br/>pet2.constructor " + (pet2.constructor == myPetConstructor.prototype.constructor);
doc.innerHTML += "<br/>"+ pet2.x1 + " -match-" + pet2.x1Return(a1);
doc.innerHTML += "<br/>" + pet2.x2 + " -match-" + pet2.x2Return(a2);
}
window.onload = function() {
//start("java", "prog");
doc = document.getElementById("output");
