第一种方法：对象冒充(临时属性)
借用临时属性，指向超类，末了删除
function Person(name,gender){
this.name=name;
this.gender=gender;
this.report=function(){
alert(this.name);
}
}
function Employee(name,gender,employeeID){
this.method=Person;
this.method(name,gender);
delete this.method;
this.employeeID=employeeID;
this.getemployeeID=function(){
alert(this.employeeID);
}
var _this=this;
this.report=function(){
setInterval(function(){
alert(_this.employeeID+":"+_this.name);
},1000)
}
}
var jj=new Employee("jj","男","24");
jj.report();
第二种方法：对象冒充(call,apply)
function Person(name,gender){
this.name=name;
this.gender=gender;
this.report=function(){
alert(this.name);
}
}
function Employee(name,gender,employeeID){
Person.apply(this,new Array(name)); //Person.call(this,name);
this.employeeID=employeeID;
this.getemployeeID=function(){
alert(this.employeeID);
}
var _this=this;
this.report=function(){
setInterval(function(){
alert(_this.employeeID+":"+_this.name);
},1000)
}
}
var jj=new Employee("jj","男","24");
jj.report();
第三种方法：原型链的方式(这种方式实例化子类时不能将参数传给父类)
最后，总结一下自认为较好的继承实现方式，成员变量采用对象冒充方式，成员方法采用原型链方式，
