-The `ng-` attributes above tell [AngularJS](http://angularjs.org/) to use the `500lines` module’s `Spreadsheet` _controller_ function, which provides a _model_— a set of names available to _bindings_ on the document _view_.

(The `ng-cloak` attribute hides the document from display until the bindings are in place.)
 
 As a concrete example, when the user clicks the `<button>` defined in the next line, its `ng-click` attribute will trigger and call `reset()` and `calc()`, two named functions provided by the JS model:

-上述的 `ng-` 特性指示 [AngularJS](http://angularjs.org/) 運行 `500lines` 模組中的 `Spreadsheet` 控制器（controller）函式來建立模型（model），也就是一組可以在文件顯示層（view）中進行繫結（binding）的名稱。`ng-cloak` 特性會先隱藏文件顯示，直到繫結已經就位為止。

 舉個具體的例子，當使用者點擊下一行中所定義的 `<button>` ，其 `ng-click` 特性會觸發並執行 `reset()` 和 `calc()` 這兩個由 JS 模型提供的函式：
