移动 Angular UI - 应用程序开发

在本章中，我们将讨论使用 AngularJS 和 Ionic 进行应用程序开发。

Ionic 是一个用于开发移动应用程序的开源框架。它提供了用于构建具有本机外观和感觉的移动 UI 的工具和服务。Ionic 框架需要本机包装器才能在移动设备上运行。

在本章中，我们将仅学习如何利用 ionic 和移动 Angular UI 来开发应用程序的基础知识。

有关离子的详细信息，请参阅 - https://www.tutorialspoint.com/ionic/index.htm。

要开始使用 ionic 和 angularjs，我们需要首先安装 cordova。命令如下 -

npm install -g cordova

使用 Cordova 创建项目设置

创建一个文件夹 ionic_mobileui/ 并在其中使用以下命令创建项目设置 -

cordova create ionic-mobileui-angularjs

这里 ionic-mobileui-angularjs 是我们应用程序的名称。

现在让我们安装项目中所需的软件包。列表如下：

npm install --save-dev angular angular-route mobile-angular-ui @ionic/core

文件已安装，文件夹结构如下所示 -

文件结构

所有 Angular 和 ionic 文件都位于 node_modules 内。我们将使用www/文件夹。因此，将 Angular 和 ionic js 和 css 文件移动到www/css/和www/js/文件夹中。

让我们使用移动角度 UI 组件修改 index.html，并在js/文件夹中添加app.js。

索引.html

      Some notes:

         * https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly 
         * Disables use of inline scripts in order to mitigate risk of XSS vulnerabilities. To change this: 
            * Enable inline JS: add 'unsafe-inline' to default-src

所有js和css文件都添加在head部分。模块和控制器是在 app.js 中创建的，如下所示 -

/* 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' 
]); 
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!"; 
});

在 www/ 文件夹中创建 home/home.html 文件。以下是 home.html 中的详细信息。

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

要使用 cordova 运行应用程序，请执行以下命令 -

cordova platform add browser

接下来，执行以下命令在浏览器中测试应用程序 -

cordova run
科尔多瓦跑

在浏览器中点击 url：http://localhost:8000来测试应用程序。

点击网址

将 Ionic 组件添加到移动 Angular UI 应用程序

打开 home/home.html，添加以下离子卡模板 -

主页/home.html

<ion-card> 
   <ion-card-header> 
      <ion-card-subtitle>Ionic Card</ion-card-subtitle> 
      <ion-card-title>Mobile Angular UI + Ionic</ion-card-title>
   </ion-card-header>

   <ion-card-content> 
      Welcome To TutorialsPoint! 
   </ion-card-content> 
</ion-card>

完成后停止 cordova 运行并再次运行。您应该看到离子卡详细信息，如下所示 -

因此，现在您可以使用 AngularJs、Mobile Angular UI 和 Ionic 创建您选择的应用程序。
