AngularJS – Controller 介紹篇

繼續AngularJS的介紹,接下來我們看看controller的應用,以商品介紹的頁面為例,來看看這些資料要如何呈現在頁面上,想要呈現的資料有產品名稱、價格以及描述。

為了方便文章閱讀,本篇將application翻譯成應用程式;controller翻譯成控制器

AngularJS Part2 Slide1

控制器負責定義函數和值來決定整個應用程式的行為,同樣我們把Javascript和HTML分開來開發,在app.js內定義應用程式名稱和控制器的名稱、函數與值,在這次的案例中也提到利用(function(){})()包裝整個javascript是一種好習慣,有關於函式的基本觀念,大家可以閱讀一下這篇文章,介紹的還蠻詳細的!包裝部分的概念可參考其中介紹的立即函示(IIFE – Immediately Invoked Function Expression)。

AngularJS Part2 Slide2

定義好之後可以開始定義該控制器內的值,其中this.product=gem的意思是指未來在輸出時可以利用product.name去取得Dodecahedron;product.price去取得2.95…等等。

AngularJS Part2 Slide3

接下來就是把這些值顯示在網頁上,首先可以在div標籤內加上ng-controller=”StoreController as store”的屬性,其中ng-controller是去指定StoreController為該div內的控制器名稱;store是別名(類似綽號)未來呼叫store時就是在呼叫StoreController這個控制器。

AngularJS Part2 Slide5

在HTML標籤內開始輸出該控制器內的值,分別是:store.product.name、store.product.price、store.product.description三個項目,而在頁面上就會看到這三個值被顯示出來了。

AngularJS Part2 Slide6

需要注意的是,如果我們把輸出值部分的程式碼放在div外側的話,會沒有辦法順利的顯示值,因為我們的控制器是指定於div標籤內,離開了div標籤就無法取得該控制器了。

AngularJS Part2 Slide7

本篇的教學就到這邊,大家也可以透過JS Bin來測試或閱讀本次案例的程式碼。

<!DOCTYPE html>
<html ng-app="store">
<head>
<meta name="description" content="controllerExample">
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js"></script>
  <meta charset="utf-8">
  <title>controllerExample</title>
</head>
<body>
  
  <div ng-controller="StoreController as store">
    <h1>{{ store.product.name }}</h1>
    <h2>{{ store.product.price }}</h2>
    <p>{{ store.product.description }}</p>
  </div>
  
</body>
</html>
(function(){
  var app = angular.module('store',[]);
  
  app.controller('StoreController',function(){
    this.product = item;
  });
  
  var item = {
    name:"馬老師雲端研究室 滑鼠墊",
    price:"350",
    description:"有些人認為滑鼠墊就只是種簡單的產品。無非是將滑鼠放於上方並將之滑來拖去。 “表面”上來說確實如此(一語雙關)。但實際上,製造能帶來卓越遊戲體驗的滑鼠墊卻需要結合眾多科學、技術和工藝。身為遊戲滑鼠技術的世界領先者,對如何使滑鼠感測器高效運作我們獨樹一幟。運用專門知識來製造適合的滑鼠墊表面,讓滑鼠感測器得以作出高效而精確的反應。",    
  };
  
})();

    German submarine U-320

    German submarine U-320 was a Type VIIC U-boat of Nazi Germany’s Kriegsmarine during World War II.

    It also contains a unified “very similar” properties menu to the one on Mac OS X, allowing you to easily transfer any change you make to this new dock.

    The N-terminal region of the presenilin 1 protein is essential for cyclophilin A cleavage in gamma-secretase activity assays.
    Presenilin 1 (PS1) is a major component of the gamma-secretase complex that cleaves the beta-amyloid precursor protein to generate the amyloid-beta peptide. PS1 has several distinct regions that appear to serve different functional roles within gamma-secretase.

    The shim functions as a user-mode hook, which means that it intercepts all Win32 API functions. A shim might run the application (for example, to collect data), complete the Win32 API function calls, or wrap the end of the Win32 API function calls with a safe function call. When a shim completes an API function call, it passes the context of the function call (for example, the input parameters and the return values of the function call) to the https://worldwidefellowship.org/wp-content/uploads/2022/06/mairag.pdf

    The clever thing about LightShow is that you can change the focus of the stage to individual lights, creating an interesting effect.

    If you want to change the speed setting and want to save it, you may use the mousewheel from that popup box to scroll down and then doubleclick the scrollbar, so that the speed setting will be set to the current mousewheel value. The speed can be altered by holding shift key and then moving the mousewheel back and forward.

    The tool is completly unintegrable in Linux, but as soon as possible I will make an deb-package for it. http://powervapes.net/zen-garden-pro-editor-v1-3-rar/
