JavaScriptMVC 的控制器可說是身兼數職：它們可以扮演 jQuery 外掛模組產生器的角
色、可以扮演檢視器的角色（負責建立一些類似分頁導覽小工具和表格控制項之類的網
頁元件）、也可以扮演控制器的角色（負責初始化控制器，並建立控制器和模型之間的
關聯）。大部分的情況下，善用控制器可說是管理程式架構的不二法門。
JavaScriptMVC 的控制器有不少實用的功能，像是：
• jQuery 外掛模組的產生器
• 自動化繫結
• 預設屬性值
• 自動化判定（Automatic determinism）
不過控制器最重要的功能，對於大部分人而言（除了 JavaScript 的重度使用者之外）似
