<script type="text/ng-template"> <div> <!-- Modal header bar --> <ion-header-bar> <h1>New Task</h1> <button ng-click="closeNewTask()">Cancel</button> </ion-header-bar> <!-- Modal content area --> <ion-content> <form ng-submit="createTask(task)"> <div> <label> <input type="text" placeholder="What do you need to do?" ng-model="task.title"> </label> </div> <div> <button type="submit">Create Task</button> </div> </form> </ion-content> </div> </script>
以上代码中我们通过 <script id=”new-task.html” type=”text/ng-template”> 定义了新的模板页面。
表单提交时触发 createTask(task) 函数。
ng-model=”task.title” 会将表单的输入数据赋值给 task 对象的 title 属性。
修改 <ion-side-menu-content> 内的内容，代码如下：
<!-- 中心内容 --> <ion-side-menu-content> <ion-header-bar> <h1>Todo</h1> <!-- 新增按钮--> <button ng-click="newTask()"> <i></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 文件中，控制器代码如下： angular.module('todo', ['ionic']) .controller('TodoCtrl', function($scope, $ionicModal) { $scope.tasks = [ { title: '菜鸟教程' }, { title: 'www.runoob.com' }, { title: '菜鸟教程' }, { title: 'www.runoob.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(); }; });
创建侧边栏
通过以上步骤我们已经实现了新增功能，现在我们为 app 添加侧边栏功能。
修改 <ion-side-menu-content> 内的内容，代码如下：
<!-- 中心内容 --> <ion-side-menu-content> <ion-header-bar> <button ng-click="toggleProjects()"> <i></i> </button> <h1>{{activeProject.title}}</h1> <!-- 新增按钮 --> <button ng-click="newTask()"> <i></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> 添加侧边栏： <!-- 左边栏 --> <ion-side-menu side="left"> <ion-header-bar> <h1>Projects</h1> <button ng-click="newProject()"> </button> </ion-header-bar> <ion-content scroll="false"> <ion-list> <ion-item ng-repeat="project in projects" ng-click="selectProject(project, $index)" ng-class="{active: activeProject == project}"> {{project.title}} </ion-item> </ion-list> </ion-content> </ion-side-menu>
<ion-item> 中的 ng-class 指令设置菜单激活样式。
这里我们创建一个新的js 文件 app2.js(为了不与前面的混淆)，代码如下：
angular.module('todo', ['ionic']) /** * The Projects factory handles saving and loading projects * from local storage, and also lets us save and load the * last active project index. */ .factory('Projects', function() { return { all: function() { var projectString = window.localStorage['projects']; if(projectString) { return angular.fromJson(projectString); } return []; }, save: function(projects) { window.localStorage['projects'] = angular.toJson(projects); }, newProject: function(projectTitle) { // Add a new project return { title: projectTitle, tasks: [] }; }, getLastActiveIndex: function() { return parseInt(window.localStorage['lastActiveProject']) || 0; }, setLastActiveIndex: function(index) { window.localStorage['lastActiveProject'] = index; } } }) .controller('TodoCtrl', function($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 中 ion-side-menus 代码如下：： <ion-side-menus> <!-- 中心内容 --> <ion-side-menu-content> <ion-header-bar> <button ng-click="toggleProjects()"> <i></i> </button> <h1>{{activeProject.title}}</h1> <!-- 新增按钮 --> <button ng-click="newTask()"> <i></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> <!-- 左边栏 --> <ion-side-menu side="left"> <ion-header-bar> <h1>Projects</h1> <button 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-side-menus>
