JavaScript物件導向編程（1）

JavaScript物件導向編程（1）

直接聲明對象

var dog = { name: 'Benji', talk: function(){ alert('Woof, woof!'); }};alert(typeof(dog));dog.talk();

這樣dog對象擁有那麼屬性和talk函數。

也可以用建構函式

//--------建構函式--------function Hero() { this.occupation = 'Ninja';//職業是武士}var hero = new Hero();//建立新對象alert(hero.occupation);//調用屬性

建構函式還可以帶參

//---------帶參的建構函式-----------function Hero(name) { this.name = name; this.occupation = 'Ninja'; //職業是武士//行為this.whoAreYou = function() { return "I'm " + this.name + " and I'm a " + this.occupation; }} var h1 = new Hero('Michelangelo'); var h2 = new Hero('Donatello'); alert(h1.whoAreYou());
