AngularJS – Directive & Filter 介紹篇
為了方便文章閱讀，本篇將filter翻譯成過濾器、directive翻譯成指示指令
在看過前幾篇的AngularJS的教學後，我們對AngularJS的開發應該有了基本的認識，針對HTML文件中我們的操作有：
針對頁面引入應用程式模組
<html ng-app="store">
針對頁面引入控制器
<body ng-controller="StoreController as store">
針對頁面去顯示或隱藏元素
<h1 ng-show="name">Hello, {{ name }} !</h1>
針對大量的資料設定重複的區域
<li ng-repeat="product in store.products">{{ product.name }}</li>
接下來針對過濾器來介紹，依下圖所示產品價格的部分，有的是有小數點有的沒有，會造成頁面在資料呈現上的參差不齊。
若我們在該表達式（expression）加上一條直線（pipe），在直線後面可以加入一些過濾器，本範例加入的是貨幣格式的過濾器，當加入後價格在頁面上顯示的格式，就會自動加上了$符號和兩位數的小數點。
我們也可以在過濾器後面利用冒號再加上一些選項，讓呈現的資料更不同，例如下圖中date格式中是以「月/日/年 @ 時:分AM」這樣的方式顯示，而除了貨幣currency、日期date的過濾器之外，還包含有大小寫轉換的uppercase、lowercase、字數也可以當成資料呈現筆數的limitTo、另外還有可以針對重複性的資料進行排序的orderBy，大概的使用方式可以參考下圖，或是在JS Bin看看馬老師製作的案例。
另外關於指示指令部分，在這次的案例上我們加上產品的圖片，圖片的部分有兩種，一個是大圖；另一個是產品的縮圖，也因為有兩種不同的資料，要注意他被加在數列裡面的方式。
在頁面上顯示圖片的方式要注意不是用src的屬性去呈現，而是需要用ng-src這個屬性，加上圖片欄位的表達式即可，在JS Bin上面觀賞本案例程式碼。
※以上截圖部分為AngularJS官方教學視訊，另有filter指令介紹的專頁和所有filter清單。

Hello this is kinda of off topic but I was wondering if blogs use WYSIWYG editors or if you have to manually code with HTML. I’m starting a blog soon but have no coding knowledge so I wanted to get advice from someone with experience. Any help would be enormously appreciated!
