Mobile Angular UI - Cordova

Cordova 是一个使用 HTML、CSS 和 JS 构建移动应用程序的平台。我们可以将 Cordova 视为将我们的 Web 应用程序与原生移动功能连接起来的容器。默认情况下，Web 应用程序无法使用原生移动功能。这就是 Cordova 发挥作用的地方。它为 Web 应用程序和移动设备之间的连接提供了桥梁。通过使用 Cordova，我们可以制作能够使用相机、地理位置、文件系统和其他原生移动功能的混合移动应用程序。

创建一个文件夹 myfirstapp 并使用下面给出的命令安装 cordova。它将全局安装 cordova。

npm install -g cordova

接下来使用 cordova − 创建一个 testapp，如下所示

D:\myfirstapp>cordova create testapp com.example.testapp HelloWorld

以下命令将创建您的应用程序 −

testapp

使用 cd testapp 进入文件夹。

添加您想要在其上提供应用程序的平台。可用的选项是 ios 和 android。现在，我们将使用以下命令添加 android 平台 −

cordova platform add android

现在安装我们项目中所需的软件包。

npm install --save-dev angular angular-route mobile-angular-ui

现在 testapp 将安装一个基本应用程序。文件夹结构如下 −

Cordova 创建一个 www/ 文件夹，用于存储项目的详细信息。index.html 是起点。您需要将 css 和 js 文件保存在 css/ 和 js/ 文件夹中。

现在让我们按照上面显示的结构安排Mobile Angular UI 应用程序。我们将所有 js 文件和 css 文件添加到 js 和 css 文件夹中，如上所示。

Javascript 文件

index.js 文件由 cordova 创建。index.js 的详细信息如下 −

var app={
   // Application Constructor
   initialize: function() {
      document.addEventListener('deviceready', this.onDeviceReady.bind(this), false);
   },

   // deviceready Event Handler
   //
   // Bind any cordova events here. Common events are:
   // 'pause', 'resume', etc.
   onDeviceReady: function() {
      this.receivedEvent('deviceready');
   },

   // Update DOM on a Received Event
   receivedEvent: function(id) {
      var parentElement=document.getElementById(id);
      var listeningElement=parentElement.querySelector('.listening');
      var receivedElement=parentElement.querySelector('.received');
      listeningElement.setAttribute('style', 'display:none;');
      receivedElement.setAttribute('style', 'display:block;');
      console.log('Received Event: ' + id);
   }
};
app.initialize();

Css 文件

cordova 添加的 index.html 如下 −

<!DOCTYPE html>
<html>
   <head>
      <meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: 
      https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *; img-src 'self' data: content:;">
      <meta name="format-detection" content="telephone=no">
      <meta name="msapplication-tap-highlight" content="no">
      <meta name="viewport" content="initial-scale=1, width=device-width, viewport-fit=cover">
      <link rel="stylesheet" type="text/css" href="css/index.css">
      <title>Hello World</title>
   </head>
   <body>
      <div class="app">
         <h1>Apache Cordova</h1>
         <div id="deviceready" class="blink">
            <p class="event listening">Connecting to Device</p>
            <p class="event received">Device is Ready</p>
         </div>
      </div>
      <script type="text/javascript" src="cordova.js"></script>
      <script type="text/javascript" src="js/index.js"></script>
   </body>
</html>

现在让我们用给定的包含我们创建的 Mobile Angular UI 应用的 index.html 来更新 index.html。

<!DOCTYPE html>
<html>
   <head>
      <meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval';

</html>

cordova 相关代码已留在 index.html 末尾。

创建 home/folder 并添加 home.html，内容如下 −

<div class="list-group text-center">
   <div class="list-group-item list-group-item-home">
      <h1>{{msg}}</h1>
   </div>
</div>

The js/app.js file is as follows −

/* eslint no-alert: 0 */

'use strict';

//
// Here is how to define your module
// has dependent on mobile-angular-ui
//
var app=angular.module('myFirstApp', [
   'ngRoute',
   'mobile-angular-ui',
   'mobile-angular-ui.gestures'
]);
app.config(function($routeProvider, $locationProvider) {
   $routeProvider
      .when("/", {
      templateUrl : "home/home.html"
   });
   $locationProvider.html5Mode({enabled:true, requireBase:false});
});
app.directive('dragItem', ['$drag', function($drag) {
   return {
      controller: function($scope, $element) {
         $drag.bind($element,
            {
               transform: $drag.TRANSLATE_BOTH,
               end: function(drag) {
                  drag.reset();
               }
            },
            {
               sensitiveArea: $element.parent()
            }
         );
      }
   };
}]);
app.controller('MainController', function($rootScope, $scope, $routeParams) {
   $scope.msg="Welcome to Tutorialspoint!";
});

我们将使用 phonegap 在浏览器中提供该应用程序。
