构造器模式 

 1 function Car(model, year, miles) {
 2     this.model = model;
 3     this.year = year;
 4     this.miles = miles;
 5 }
 6 
 7 Car.prototype.toString = function() {
 8     return this.model + " has done " + this.miles + " miles";
 9 };
10 
11 var civic = new Car("Honda Civic", 2009, 20000);
12 var mondeo = new Car("Ford Mondeo", 2010, 5000);
13 
14 console.log(civic.toString());
15 console.log(mondeo.toString());

 

简单说，构造函数就是new一个
