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 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 文件中，控制器代码如下：
angular.module('todo', ['ionic'])
.controller('TodoCtrl', function($scope, $ionicModal) {
$scope.tasks = [
{ title: 'W3Cschool在线教程' },
{ title: '' },
{ title: 'W3Cschool在线教程' },
{ title: '' }
];
// 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 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>添加侧边栏：
<!-- 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, $index)" ng-class="{active: activeProject == project}">
{{project.title}}
</ion-item>
</ion-list>
</ion-content>
</ion-side-menu><ion-item> 中的 ng-class 指令设置菜单激活样式。
这里我们创建一个新的js 文件 app2.js(为了不与前面的混淆)，代码如下：
angular.module('todo', ['ionic'])
/**
* The Projects factory handles saving and loading projects
* from local storage, and also lets us save and load the
* last active project index.
*/
.factory('Projects', function() {
return {
all: function() {
var projectString = window.localStorage['projects'];
if(projectString) {
return angular.fromJson(projectString);
}
return [];
},
save: function(projects) {
window.localStorage['projects'] = angular.toJson(projects);
},
newProject: function(projectTitle) {
// Add a new project
return {
title: projectTitle,
tasks: []
};
},
getLastActiveIndex: function() {
return parseInt(window.localStorage['lastActiveProject']) || 0;
},
setLastActiveIndex: function(index) {
window.localStorage['lastActiveProject'] = index;
}
}
})
.controller('TodoCtrl', function($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 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>
<!-- 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-side-menus>尝试一下 ?
