ionic create APP

The previous chapters we have learned how ionic framework into the project.

Next we will introduce how to create an ionic APP application.

ionic create APP using HTML, CSS and Javascript to build, so we can create a www directory, and create the index.html file in the directory, as follows:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>Todo</title>
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">

    <link href="lib/ionic/css/ionic.css" rel="stylesheet">

    <script src="lib/ionic/js/ionic.bundle.js"></script>

    <!-- 在使用 Cordova/PhoneGap 创建的 APP 中包含的文件,由 Cordova/PhoneGap 提供,(开发过程中显示 404) -->
    <script src="cordova.js"></script>
  </head>
  <body>
  </body>
</html>

The above code, we introduced the Ionic CSS file, Ionic JS file extension and Ionic AngularJS ionic.bundle.js (ionic.bundle.js).

ionic.bundle.js file already contains Ionic core JS, AngularJS, Ionic extension of AngularJS, Angular if you need to introduce other modules can be called from lib / js / angular directory.

cordova.js when using Cordova / PhoneGap Create generate the application and does not require manual introduction, you can find the file in Cordova / PhoneGap project, so the display in the development process 404 is normal.


Create APP

Next we come to realize the application that contains the title, sidebar, lists, etc., the design is as follows:

Create sidebar

Sidebar created using the ion-side-menus controller.

Edit index.html file we created earlier, modify the contents of the <body>, as follows:

<body>
  <ion-side-menus>
    <ion-side-menu-content>
    </ion-side-menu-content>
    <ion-side-menu side="left">
    </ion-side-menu>
  </ion-side-menus>
</body>

Controllers interpret:

  • ion-side-menus: a container with a sidebar menu, you can click a button or slide the screen to expand the menu.
  • ion-side-menu-content: display the main content of the container, you can expand the menu by sliding the screen.
  • ion-side-menu: receptacle sidebar.

Initialization APP

Next, we create a new AngularJS module, and initialize code is www / js / app.js in:

angular.module('todo', ['ionic'])

After you add ng-app property in our body tag:

<body ng-app="todo">

In the index.html file <script src = "cordova.js"> </ script> The above is introduced app.js file:

<script src="js/app.js"></script>

Modify the contents of the index.html file body tag, the code is as follows:

<body ng-app="todo">
  <ion-side-menus>

    <!-- 中心内容 -->
    <ion-side-menu-content>
      <ion-header-bar class="bar-dark">
        <h1 class="title">Todo</h1>
      </ion-header-bar>
      <ion-content>
      </ion-content>
    </ion-side-menu-content>

    <!-- 左侧菜单 -->
    <ion-side-menu side="left">
      <ion-header-bar class="bar-dark">
        <h1 class="title">Projects</h1>
      </ion-header-bar>
    </ion-side-menu>

  </ion-side-menus>
</body>

try it"

We have completed the above steps ionic basic APP applications.


Create a list

First, create a controllerTodoCtrl:

<body ng-app="todo" ng-controller="TodoCtrl">

In app.js file, use the controller to define a list of data:

angular.module('todo', ['ionic'])

.controller('TodoCtrl', function($scope) {
  $scope.tasks = [
    { title: '本教程' },
    { title: 'www.w3big.com' },
    { title: '本教程' },
    { title: 'www.w3big.com' }
  ];
});

Data index.html page in the list we use to iterate Angular ng-repeat data:

<!-- 中心内容 -->
<ion-side-menu-content>
  <ion-header-bar class="bar-dark">
    <h1 class="title">Todo</h1>
  </ion-header-bar>
  <ion-content>
    <!-- 列表 -->
    <ion-list>
      <ion-item ng-repeat="task in tasks">
        {{task.title}}
      </ion-item>
    </ion-list>
  </ion-content>
</ion-side-menu-content>

After modifying index.html body tag within the code is as follows:

 <body ng-app="todo" ng-controller="TodoCtrl">
    <ion-side-menus>

    <!-- 中心内容 -->
    <ion-side-menu-content>
      <ion-header-bar class="bar-dark">
        <h1 class="title">Todo</h1>
      </ion-header-bar>
      <ion-content>
        <!-- 列表 -->
        <ion-list>
          <ion-item ng-repeat="task in tasks">
            {{task.title}}
          </ion-item>
        </ion-list>
      </ion-content>
    </ion-side-menu-content>

    <!-- 左侧菜单 -->
    <ion-side-menu side="left">
      <ion-header-bar class="bar-dark">
        <h1 class="title">Projects</h1>
      </ion-header-bar>
    </ion-side-menu>

    </ion-side-menus>
    <script src="http://www.w3big.com/static/ionic/js/app.js"></script>
    <script src="cordova.js"></script>
</body>

try it"


Create add pages

Modify index.html in</ ion-side-menus> After you add the following code:

<script id="new-task.html" type="text/ng-template">

  <div class="modal">

    <!-- Modal header bar -->
    <ion-header-bar class="bar-secondary">
      <h1 class="title">New Task</h1>
      <button class="button button-clear button-positive" ng-click="closeNewTask()">Cancel</button>
    </ion-header-bar>

    <!-- Modal content area -->
    <ion-content>

      <form ng-submit="createTask(task)">
        <div class="list">
          <label class="item item-input">
            <input type="text" placeholder="What do you need to do?" ng-model="task.title">
          </label>
        </div>
        <div class="padding">
          <button type="submit" class="button button-block button-positive">Create Task</button>
        </div>
      </form>

    </ion-content>

  </div>

</script>

Through the above code<script id = "new-task.html " type = "text / ng-template"> defines a new template page.

createTask (task) function is triggered when the form is submitted.

ng-model = input data "task.title" form will be assigned to the task object title attribute.

Content<ion-side-menu-content > within the code is as follows:

<!-- 中心内容 -->
<ion-side-menu-content>
<ion-header-bar class="bar-dark">
  <h1 class="title">Todo</h1>
  <!-- 新增按钮-->
  <button class="button button-icon" ng-click="newTask()">
    <i class="icon ion-compose"></i>
  </button>
</ion-header-bar>
<ion-content>
  <!-- 列表 -->
  <ion-list>
    <ion-item ng-repeat="task in tasks">
      {{task.title}}
    </ion-item>
  </ion-list>
</ion-content>
</ion-side-menu-content>

app.js file, the controller code as follows:

angular.module('todo', ['ionic'])

.controller('TodoCtrl', function($scope, $ionicModal) {
  $scope.tasks = [
    { title: '本教程' },
    { title: 'www.w3big.com' },
    { title: '本教程' },
    { title: 'www.w3big.com' }
  ];

  // 创建并载入模型
  $ionicModal.fromTemplateUrl('new-task.html', function(modal) {
    $scope.taskModal = modal;
  }, {
    scope: $scope,
    animation: 'slide-in-up'
  });

  // 表单提交时调用
  $scope.createTask = function(task) {
    $scope.tasks.push({
      title: task.title
    });
    $scope.taskModal.hide();
    task.title = "";
  };

  // 打开新增的模型
  $scope.newTask = function() {
    $scope.taskModal.show();
  };

  // 关闭新增的模型
  $scope.closeNewTask = function() {
    $scope.taskModal.hide();
  };
});

Create sidebar

Through the above steps we have implemented new features, now we add functionality to sidebar app.

Content<ion-side-menu-content > within the code is as follows:

<!-- 中心内容 -->
<ion-side-menu-content>
  <ion-header-bar class="bar-dark">
    <button class="button button-icon" ng-click="toggleProjects()">
      <i class="icon ion-navicon"></i>
    </button>
    <h1 class="title">{{activeProject.title}}</h1>
    <!-- 新增按钮 -->
    <button class="button button-icon" ng-click="newTask()">
      <i class="icon ion-compose"></i>
    </button>
  </ion-header-bar>
  <ion-content scroll="false">
    <ion-list>
      <ion-item ng-repeat="task in activeProject.tasks">
        {{task.title}}
      </ion-item>
    </ion-list>
  </ion-content>
</ion-side-menu-content>

Add a sidebar:

<!-- 左边栏 -->
<ion-side-menu side="left">
<ion-header-bar class="bar-dark">
  <h1 class="title">Projects</h1>
  <button class="button button-icon ion-plus" ng-click="newProject()">
  </button>
</ion-header-bar>
<ion-content scroll="false">
  <ion-list>
    <ion-item ng-repeat="project in projects" ng-click="selectProject(project, $index)" ng-class="{active: activeProject == project}">
      {{project.title}}
    </ion-item>
  </ion-list>
</ion-content>
</ion-side-menu>

<Ion-item> ng-class instruction in the setup menu active style.

Here we create a new js file app2.js (not to be confused with the preceding), as follows:

angular.module('todo', ['ionic'])
/**
 * The Projects factory handles saving and loading projects
 * from local storage, and also lets us save and load the
 * last active project index.
 */
.factory('Projects', function() {
  return {
    all: function() {
      var projectString = window.localStorage['projects'];
      if(projectString) {
        return angular.fromJson(projectString);
      }
      return [];
    },
    save: function(projects) {
      window.localStorage['projects'] = angular.toJson(projects);
    },
    newProject: function(projectTitle) {
      // Add a new project
      return {
        title: projectTitle,
        tasks: []
      };
    },
    getLastActiveIndex: function() {
      return parseInt(window.localStorage['lastActiveProject']) || 0;
    },
    setLastActiveIndex: function(index) {
      window.localStorage['lastActiveProject'] = index;
    }
  }
})

.controller('TodoCtrl', function($scope, $timeout, $ionicModal, Projects, $ionicSideMenuDelegate) {

  // A utility function for creating a new project
  // with the given projectTitle
  var createProject = function(projectTitle) {
    var newProject = Projects.newProject(projectTitle);
    $scope.projects.push(newProject);
    Projects.save($scope.projects);
    $scope.selectProject(newProject, $scope.projects.length-1);
  }


  // Load or initialize projects
  $scope.projects = Projects.all();

  // Grab the last active, or the first project
  $scope.activeProject = $scope.projects[Projects.getLastActiveIndex()];

  // Called to create a new project
  $scope.newProject = function() {
    var projectTitle = prompt('Project name');
    if(projectTitle) {
      createProject(projectTitle);
    }
  };

  // Called to select the given project
  $scope.selectProject = function(project, index) {
    $scope.activeProject = project;
    Projects.setLastActiveIndex(index);
    $ionicSideMenuDelegate.toggleLeft(false);
  };

  // Create our modal
  $ionicModal.fromTemplateUrl('new-task.html', function(modal) {
    $scope.taskModal = modal;
  }, {
    scope: $scope
  });

  $scope.createTask = function(task) {
    if(!$scope.activeProject || !task) {
      return;
    }
    $scope.activeProject.tasks.push({
      title: task.title
    });
    $scope.taskModal.hide();

    // Inefficient, but save all the projects
    Projects.save($scope.projects);

    task.title = "";
  };

  $scope.newTask = function() {
    $scope.taskModal.show();
  };

  $scope.closeNewTask = function() {
    $scope.taskModal.hide();
  }

  $scope.toggleProjects = function() {
    $ionicSideMenuDelegate.toggleLeft();
  };


  // Try to create the first project, make sure to defer
  // this by using $timeout so everything is initialized
  // properly
  $timeout(function() {
    if($scope.projects.length == 0) {
      while(true) {
        var projectTitle = prompt('Your first project title:');
        if(projectTitle) {
          createProject(projectTitle);
          break;
        }
      }
    }
  });

});

body in ion-side-menus code is as follows ::

<ion-side-menus>

<!-- 中心内容 -->
<ion-side-menu-content>
  <ion-header-bar class="bar-dark">
    <button class="button button-icon" ng-click="toggleProjects()">
      <i class="icon ion-navicon"></i>
