【實踐】一個簡單卻五臟俱全的JavaScript“類”例子

JavaScript的OOP，從這裏可以理解與掌握，今後的應用就得靠自己了。

定義：

// Constructor
function Kid (name) {
	// Private
	var idol = "Paris Hilton";

	// Privileged
	this.getIdol = function () {
		return idol;
	};

	// Public
	this.name = name;
}

// Public
Kid.prototype.getName = function () {
	return this.name;
};

// Static property
Kid.town = "South Park";

-------------------------------

驗證上面的類：

 // Create a new instance

var cartman = new Kid("Cartman");

// Access private property
cartman.idol; // undefined

// Access privileged method
cartman.getIdol(); // "Paris Hilton"

// Access public property
cartman.name; // "Cartman"

// Access public method
cartman.getName(); // "Cartman"

// Access static property on an instance
cartman.town; // undefined

// Access static property on the constructor object
Kid.town; // "South Park"
