javascript设计模式Constructor（构造器）模式

 //设置属性
newObj.name = 'LanFeng';
//获取值
var user= newObj.name;

 //设置属性
newObj["name"]= 'LanFeng';
//获取值
var user= newObj["name"];

 //设置属性
Object.defineProperty(newObj,"name",{
  value:"LanFeng",
  writable:true,
  enumerable:true,
  configurable:true
})

 //设置属性
 Object.defineProperties(newObj,{
   "someKey":{
    value:"Hello Js",
     writable:true
  },
  "anotherKey":{
    value:"Foo bar",
    writable:false
  }
})

function Car(model,year,miles){
  this.model = model;
  this.year = year;
  this.miles = miles;
  this.toString = function(){
  return this.model + "has done" + this.miles +"miles";
  }
}
//创建实例化对象

var civio = new Car("Honda Civio",2009,20000);

var mondeo= new Car("Ford Mondeo",2009,5000);

function Car(model,year,miles){
  this.model = model;
  this.year = year;
  this.miles = miles;

}


//原型函数
Car.prototype.toString = function(){
  return this.model + "has done" + this.miles +"miles";
  }

//创建实例化对象

var civio = new Car("Honda Civio",2009,20000);
var mondeo= new Car("Ford Mondeo",2009,5000);
console.log(civio.toString())
console.log(mondeo.toString())
