javascript继承之借用构造函数(二)

 1 //简单的函数调用
 2         function Father() {
 3             this.nums= [1,2];
 4         }
 5         function Son() {
 6             Father.call(this);//调用超类型,完成son继承father
 7         }
 8         var s1 = new Son();
 9         s1.nums.push("yellow");
10         alert(s1.nums);//red,black,yellow
11         var s2 = new Son();
12         alert(s2.nums); //red,black

 1 //向父类传参
 2         function Human(name) {
 3             this.name = name;
 4         }
 5         function Man(name,age) {
 6             Human.call(this, name);
 7             this.age = age;
 8         }
 9         var yaoMing = new Man("姚明",42); 
10         alert(yaoMing.name);//姚明
11         alert(yaoMing.age);//42
