js类公有属性和私有属性

function Test(){
	var name = 'test'//私有
	this.age = 12//公有
	this.getName = function(){
		return name
	}
	this.getAge = function(){
		return this.age
	}
}

var Test = new Test()
print(Test.name)//undefined
print(Test.age)//12
print(Test.getAge())//12
print(Test.getName())//'test'

模块模式

var singleton = function(){
	//私有变量和函数
	var privateVariable = 10
	function privateFunction(){
		return false
	}

	//创建对象
	var object = new CustomType()

	object.publicProperty = true;
	object.publicMethod = function(){
		privateVariable++
		return privateFunction()
	}

	return object;

    //特权/公有方法和属性
	// return {
	// 	publicProperty:true,
	// 	publicMethod:function(){
	// 		privateVariable++
	// 		return privateFunction()
	// 	}
	// }
}()

//单例接口
var application = function(){
	//私有
	var components = new Array()
	components.push(new BaseComponent())//BaseComponent()作为初始化操作

	var app = new BaseComponent()

	app.getComponentCount = function(){
		return components.length
	}

	app.registerComponent = function(component){
		if(typeof component == "object"){
			components.push(component)
		}
	}

	return app

	// return {
	// 	getComponentCount:function(){//返回已注册的组件数
	// 		return components.length
	// 	},
	// 	registerComponent:function(component){//注册新组件
	// 		if(typeof component == "object"){
	// 			components.push(component)
	// 		}
	// 	}
	// }
}
