一.采用json的方式来定义
var xiaoxing = {
grade:1,
name : "xiaoxing",
age:27, sex:"男",
speak:function(words) {
alert(this.name+"说:"+words+"!");
},
improve:function() { this.grade++; }
}
这样,我就变成了一个对象了,你可以让我跟你说一句话
xiaoxing.speak("欢迎"); while(i have friends) { xiaoxing.improve(); }
二,在用他的prototype原型对象的方式来定义其属性,事件等,方便继承扩展。
//创建原型对象,定义属性、方法、及对象事件等。
Student.prototype=
{
_name:null,
_age:null,
_sex:null,
ShowName:function()
{
alert("Name:"+ this._name +"\n" + "Age:" + this._age + "\n" + "Sex:"+ this._sex);
}
}
//专门用一个函数来初始化对象。
function Student(name,age,sex)
{
this._name=name;
this._age=age;
this._sex=sex;
}
var student=new Student("Young",25,"男"); //实例化
student.ShowName(); //调用对象方法
三,构造函数方式
function Student(name,age,sex)
{
this._name=name;
this._age=age;
this._sex=sex;
this.ShowName=function()
{
alert("Name:"+ this._name +"\n" + "Age:" + this._age + "\n" + "Sex:"+ this._sex);
};
}
var student=new Student("Young",25,"男"); //实例化
student.ShowName(); //调用对象方法
四,这种方式和方式二差不多,采用类得方式来定义
var person = new Function();//或var person = function(){}都可以
person.prototype={
grade:0,
age:0,
sex:null,
name:null,
speak:function(words)
{
alert(this.name+"说:"+words+"!");
},
init:function(_grade,_age,_sex,_name)
{
this.grade = _grade;this.age=_age;this.sex=_sex;this.name=_name;
}
}
var xiaoxing = new person();
xiaoxing.init("10","27","男","xiaoxing");
xiaoxing.speak("hello everybody");
