几行代码立即理解js的对象，类，原型等概念

function People(name)
{
this.name=name;
//对象方法
this.Introduce=function(){
alert("My name is "+this.name);
}
}
//类方法
People.Run=function(){
alert("I can run");
}
//原型方法
People.prototype.IntroduceChinese=function(){
alert("我的名字是"+this.name);
}

 

//测试

var p1=new People("Windking");

p1.Introduce();

People.Run();

p1.IntroduceChinese();

function People(){
  this.say=function(){
    console.log('Class');
  }
}
People.prototype.sayHi=function(){
   //为People添加一个原型方法，所有People的实例都可以访问
   console.log('Hi!');
}

People.say=function(){
  //为People添加一个类方法，仅以People为对象时可以访问
  console.log('Object');
}

var p=new People();
p.say(); //Class
People.say(); //Object
p.sayHi(); //Hi
People.sayHi(); //error
