開發抽象化的函式庫介面
我們可以利用稍早所學，開發出抽象化的函式庫介面，好讓這些程式能被其他的模組、
控制器被重複利用。除了原先的
load()
函式之外，我們也可以加入一些新的函式，像
proxy()
和
include()
：
(function($, exports){
var mod = function(includes){
if (includes) this.include(includes);
};
mod.fn = mod.prototype;
mod.fn.proxy = function(func){
return $.proxy(func, this);
};
mod.fn.load = function(func){
$(this.proxy(func));
};
mod.fn.include = function(ob){
$.extend(this, ob);
};
exports.Controller = mod;
})(jQuery, window);
proxy()
是用來確保函式的執行環境，會被限制在一塊封閉的區域環境裡，這種做法對
於事件的回叫函式而言非常方便。
include()
函式只是個快捷函式，用來幫控制器新增
屬性，並讓你可少打些字。
最後，我們會把函式庫加進
exports
物件裡，將它匯出成全域變數
Controller
。如此，
就可以在其他模組裡面，利用
Controller
的建構函式建立它的物件實體。接下來這段簡
