javascript 写类方式之十

/*
*Script: Class.js
*/
var Class = new Native({
name: 'Class',

initialize: function(properties){
properties = properties || {};
var klass = function(empty){
for (var key in this) this[key] = $unlink(this[key]);
for (var mutator in Class.Mutators){
if (!this[mutator]) continue;
Class.Mutators[mutator](this, this[mutator]);
delete this[mutator];
}
this.constructor = klass;
if (empty === $empty) return this;

var self = (this.initialize) ? this.initialize.apply(this, arguments) : this;
if (this.options && this.options.initialize) this.options.initialize.call(this);
return self;
};

$extend(klass, this);
klass.constructor = Class;
klass.prototype = properties;
return klass;
}
});

/**
* Person类
* @param {Object} name
*/
var Person = new Class({
initialize: function(name){
this.name = name;
},
setName : function(name) {
this.name = name;
},
getName : function() {
return this.name;
}
})

//new一个对象
var p = new Person("jack");

//测试set，get方法
console.log(p.getName());//jac
p.setName('andy');
console.log(p.getName());//andy

//测试instanceof及p.constructor是否正确指向了Person
console.log(p instanceof Person); //true
console.log(p.constructor == Person); //true
