JavaScript 变量对象

Question

我对 Javascript 很陌生请更正我的代码或建议最佳选择

var myApp = {};

myApp.set = function(VAL) {
    myApp.id = VAL;    
}

myApp.get = function() {
    return myApp.id; 
}

function PageLoad() {
    var X = new myApp;
    var Y = new myApp;

    Y.set(20);
    X.set(10);

    alert(X.get());
    alert(Y.get());
} 

它仅显示最后一个分配值，即 10 :(

@Manoj Chavanke先生请使用此代码

 function myApp(){
    }
    myApp.prototype.set = function(VAL) {
        this.id = VAL;    
    }

    myApp.prototype.get = function() {
        return this.id; 
    }

    function PageLoad() {
        var X = new myApp; console.log(X);
        var Y = new myApp; console.log(Y);

        Y.set(20);
        X.set(10);

        alert(X.get());
        alert(Y.get());
    }
    PageLoad();
