复制代码 代码如下:

function P(name){
this.name=name;

this.p1=function(){
alert('Parent Constructor');
}
return this;
}
function C(name,id){
//this.method=P;
//this.method(name); //1st method
//P.call(this,name); //2nd method
P.apply(this,new Array(name));//3rd method
this.id=id;
this.dis=function(){
alert(this.name);
}
}
function dis(){
alert(this.name);
}
function t(){
var cc=new C('N','Id');
cc.dis();
cc.p1();
}
