js继承有好多种实现形式，下面来讲一下基于类的继承

function person (name,age) {this.name = name;this.age = age;this.like= [];
}
person.prototype.say = function ()  {  console.log(this.name + " , " + this.age +" , " + this.like);  }  function student (name, age, no) {
person.call(this,name,age);
this.no = no; 
}student .prototype = new person();  var stu1 = new student ("0001","张三",11);  stu1.like.push("java");  stu1.say();  var stu2 = new student ("0002","李四",12);  stu2.like.push("sql");  stu2.like.push("javaScript");  stu2.say(); 

输出结果

0001 , 张三 , java
VM220:8 0002 , 李四 , sql,javaScript
