AngularJS中ui-router全攻略
首先是angular-ui-router的基本用法。
■ 如何引用依赖angular-ui-router
angular.module('app',["ui.router"]).config(function($stateProvider){$stateProvider.state(stateName, stateCofig);})■ $stateProvider.state(stateName, stateConfig)
stateName是string类型
stateConfig是object类型
//statConfig可以为空对象
$stateProvider.state("home",{});
//state可以有子父级
$stateProvider.state("home",{});
$stateProvider.state("home.child",{})
//state可以是链式的
$stateProvider.state("home",{}).state("about",{}).state("photos",{});
stateConfig包含的字段：template, templateUrl, templateProvider, controller, controllerProvider, resolve, url, params, views, abstract, onEnter, onExit, reloadOnSearch, data
■ $urlRouteProvider
$urlRouteProvider.when(whenPath, toPath)
$urlRouterProvider.otherwise(path)
$urlRouteProvider.rule(handler)
■ $state.go
$state.go(to, [,toParams],[,options])
形参to是string类型，必须，使用"^"或"."表示相对路径；
形参toParams可空，类型是对象；
形参options可空，类型是对象，字段包括：location为bool类型默认true,inherit为bool类型默认true, relative为对象默认$state.$current,notify为bool类型默认为true, reload为bool类型默认为false
$state.go('photos.detail')
$state.go('^')到上一级,比如从photo.detail到photo
$state.go('^.list')到相邻state,比如从photo.detail到photo.list
$state.go('^.detail.comment')到孙子级state，比如从photo.detail到photo.detial.comment
■ ui-sref
ui-sref='stateName'
ui-sref='stateName({param:value, param:value})'
■ ui-view
==没有名称的ui-view
<div ui-view></div>
$stateProvider.state("home",{template: "<h1>hi</h1>"
})或者这样配置：
$stateProvider.state("home"{views: {"": {template: "<h1>hi</h1>"}}
})==有名称的ui-view
<div ui-view="main"></div>
$stateProvider.state("home",{views: {"main" : {template: "<h1>hi</h1>"}}
})==多个ui-view
<div ui-view></div>
<div ui-view="data"></div>
$stateProvider.state("home",{views: {"":{template: "<h1>hi</h1>"},"data": {template: "<div>data</div>"}}
})■ 项目文件结构
node_modules/
partials/
.....about.html
.....home.html
.....photos.html
app.js
index.html
■ 创建state和view
app.js
var photoGallery = angular.module('photoGallery',["ui.router"]);photoGallery.config(function($stateProvider, $urlRouterProvider){$urlRouterProvider.otherwise('/home');$stateProvider.state('home',{url: '/home',templateUrl: 'partials/home.html'}).state('photos',{url: '/photos',templateUrl: 'partials/photos.html'}).state('about',{url: '/about',templateUrl: 'partials/about.html'})
})index.html
<!DOCTYPE html> <html lang="en" ng-app="photoGallery"> <head><meta charset="UTF-8"><title></title><link rel="stylesheet" href="node_modules/bootstrap/dist/css/bootstrap.css"/> </head> <body><h1>Welcome</h1><div ui-view></div><script src="node_modules/jquery/dist/jquery.js"></script><script src="node_modules/angular/angular.js"></script> <script src="node_modules/angular-ui-router/release/angular-ui-router.js"></script> <script src="node_modules/angular-animate/angular-animate.js"></script><script src="node_modules/bootstrap/dist/js/bootstrap.js"></script> <script src="node_modules/angular-bootstrap/ui-bootstrap-tpls.js"></script><script src="app.js"></script> </body> </html>
■ state之间的跳转
index.html
<nav class="navbar navbar-inverse"> <div class="container-fluid"><div class="navbar-header"><button class="navbar-toggle collapsed" type="button" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span></button><a ui-sref="home" class="navbar-brand">Home</a></div><div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"><ul class="nav navbar-nav"><li><a ui-sref="photos">Photos</a></li><li><a ui-sref="about">About</a></li></ul></div> </div> </nav><div ui-view></div>
以上通过ui-sref属性完成state之间的跳转。
■ 多个view以及state嵌套
有时候，一个页面上可能有多个ui-view，比如：
<div ui-view="header"></div>
<div ui-view="body"></div>
假设，以上页面属于一个名称为parent的state中。
我们知道在ui-router中，一个state大致是这样设置的：
.state('content.photos',{url: 'photos',views:{"body@content":{templateUrl: 'partials/photos.html'}}
})所有state下views下的所有键值对(类似 "body@content":{templateUrl: 'partials/photos.html'})都被放到一个键值集合中。而ui-view的工作原理就是根据自己的属性值，到这个键值集合中去找匹配的键，找到就把对应的页面显示出来。
点击header对应的页面链接，可能会跳转到另外的子页面出现在<div ui-view="body"></div>这个位置。这时候页面出现了子父关系，而每个页面都属于某个state,这样state间就出现了子父关系。这些跳转的子页面，在路由设置中，可能被称为parent.son1, parent.son2...这就是state的嵌套。
在现有的文件结构上增加content.html, header.html,文件结构变为：
node_modules/
partials/
.....about.html
.....home.html
.....photos.html
.....content.html
.....header.html
app.js
index.html
content.html 包含了多各ui-view, 一个ui-view和页头相关，保持不变；令一个ui-view和会根据页头上的点击呈现不同的内容
<div ui-view="header"></div>
<div ui-view="body"></div>
header.html 把原先indext.html中nav部分放到这里来
<nav class="navbar navbar-inverse"><div class="container-fluid"><div class="navbar-header"><button class="navbar-toggle collapsed" type="button" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span></button><a ui-sref="content.home" class="navbar-brand">Home</a></div><div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"><ul class="nav navbar-nav"><li><a ui-sref="content.photos">Photos</a></li><li><a ui-sref="content.about">About</a></li></ul></div></div> </nav>
index.html 这时变成了这样
<div ui-view></div>
app.js 路由现在这样设置
var photoGallery = angular.module('photoGallery',["ui.router"]);photoGallery.config(function($stateProvider, $urlRouterProvider){$urlRouterProvider.otherwise('home');$stateProvider.state('content',{url: '/',views:{"":{templateUrl: 'partials/content.html'},"header@content":{templateUrl: 'partials/header.html'},}}).state('content.home',{url: 'home',views:{"body@content":{templateUrl: 'partials/home.html'}}}).state('content.photos',{url: 'photos',views:{"body@content":{templateUrl: 'partials/photos.html'}}}).state('content.about',{url:'about',views:{"body@content":{templateUrl: 'partials/about.html'}}})
})这时候，页面是这样呈现出来的：
→ 来到home这个路由
.state('content.home',{url: 'home',views:{"body@content":{templateUrl: 'partials/home.html'}}
})以上，告诉我们partials/home.html将会被加载到与"body@content"匹配的ui-view中。暂时对应的ui-view还没有出现，于是等待。
→ 路由看到index.html上的<div ui-view></div>
.state('content',{url: '/',views:{"":{templateUrl: 'partials/content.html'},"header@content":{templateUrl: 'partials/header.html'},}
})于是，就找到了content这个state下views下的 "":{templateUrl: 'partials/content.html'}这个键值对，把partials/content.html显示出来。
→ 分别加载partials/content.html页面上的各个部分
看到<div ui-view="header"></div>，就加载如下：
"header@content":{templateUrl: 'partials/header.html'},
看到<div ui-view="body"></div>，先加载 "body@content":{templateUrl: 'partials/home.html'}
→ 点击header上的链接
点击<a ui-sref="content.photos">Photos</a>，来到：
.state('content.photos',{url: 'photos',views:{"body@content":{templateUrl: 'partials/photos.html'}}
})把partials/photos.html显示到<div ui-view="body"></div>中去。
点击<div ui-view="body"></div>，来到：
.state('content.about',{url:'about',views:{"body@content":{templateUrl: 'partials/about.html'}}
})把partials/about.html显示到<div ui-view="body"></div>中去。
■ state多级嵌套
以上，在路由设置中，state名称有content, content.photos有了这样的一层嵌套。接下来，要实现state的多级嵌套。
在photos.html页面准备加载一个子页面，叫做photos-list.html；
与photo-list.html页面相邻的还有一个页面，叫做photo-detail.html；
在photo-detail.html页面上加载一个子页面，叫做photos-detail-comment.html;
这样，页面有了嵌套关系，state也相应的会有嵌套关系。
现在，文件结构变成：
node_modules/
partials/
.....about.html
.....home.html
.....photos.html
.....content.html
.....header.html
.....photos-list.html
.....photo-detail.html
.....photos-detail-comment.html
app.js
index.html
photos.html 加一个容纳子页面的ui-view
photos
<div ui-view></div>
如何到达这个子页面呢？修改header中的相关部分如下：
<nav class="navbar navbar-inverse"><div class="container-fluid"><div class="navbar-header"><button class="navbar-toggle collapsed" type="button" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span></button><a ui-sref="content.home" class="navbar-brand">Home</a></div><div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"><ul class="nav navbar-nav"><li><a ui-sref="content.photos.list">Photos</a></li><li><a ui-sref="content.about">About</a></li></ul></div></div>
以上，通过<a ui-sref="content.photos.list">Photos</a>来到photos.html的子页面photos-list.html.
photos-list.html 通过2种途径到相邻页photo-detail.html
<h1>photos-list</h1> <ul><li><a ui-sref="^.detail">我通过相对路径到相邻的state</a></li><li><a ui-sref="content.photos.detail">我通过绝对路径到相邻的state</a></li> </ul>
photo-detail.html 又提供了来到其子页面photos-detail-comment.html的ui-view
<h1>photo-details</h1> <a class="btn btn-default" ui-sref=".comment">通过相对路径去子state</a> <div ui-view></div>
photos-detail-comment.html 则很简单：
<h1>photos-detail-comment</h1>
app.js state多级嵌套的设置为
var photoGallery = angular.module('photoGallery',["ui.router"]);photoGallery.config(function($stateProvider, $urlRouterProvider){$urlRouterProvider.otherwise('home');$stateProvider.state('content',{url: '/',views:{"":{templateUrl: 'partials/content.html'},"header@content":{templateUrl: 'partials/header.html'},}}).state('content.home',{url: 'home',views:{"body@content":{templateUrl: 'partials/home.html'}}}).state('content.photos',{url: 'photos',views:{"body@content":{templateUrl: 'partials/photos.html'}}}).state('content.photos.list',{url: '/list',templateUrl: 'partials/photos-list.html'}).state('content.photos.detail',{url: '/detail',templateUrl: 'partials/photos-detail.html'}).state('content.photos.detail.comment',{url: '/comment',templateUrl: 'partials/photos-detail-comment.html'}).state('content.about',{url:'about',views:{"body@content":{templateUrl: 'partials/about.html'}}})
})■ 抽象state
如果一个state,没有通过链接找到它，那就可以把这个state设置为abstract:true,我们把以上的content和content.photos这2个state设置为抽象。
.state('content',{url: '/',abstract: true,views:{"":{templateUrl: 'partials/content.html'},"header@content":{templateUrl: 'partials/header.html'},}
})
....state('content.photos',{url: 'photos',abstract: true,views:{"body@content":{templateUrl: 'partials/photos.html'}}
})那么，当一个state设置为抽象，如果通过ui-sref或路由导航到该state会出现什么结果呢？
--会导航到默认路由上
$urlRouterProvider.otherwise('home');
即
.state('content.home',{url: 'home',views:{"body@content":{templateUrl: 'partials/home.html'}}
})最终把partials/home.html显示出来。
■ 使用控制器
在实际项目中，数据大多从controller中来。
首先在路由中设置state所用到的控制器以及控制器别名。
var photoGallery = angular.module('photoGallery',["ui.router"]);photoGallery.config(function($stateProvider, $urlRouterProvider){$urlRouterProvider.otherwise('home');$stateProvider.state('content',{url: '/',abstract: true,views:{"":{templateUrl: 'partials/content.html'},"header@content":{templateUrl: 'partials/header.html'},}}).state('content.home',{url: 'home',views:{"body@content":{templateUrl: 'partials/home.html',controller: 'HomeController',controllerAs: 'ctrHome'}}}).state('content.photos',{url: 'photos',abstract: true,views:{"body@content":{templateUrl: 'partials/photos.html',controller: 'PhotoController',controllerAs: 'ctrPhoto'}}}).state('content.photos.list',{url: '/list',templateUrl: 'partials/photos-list.html',controller: "PhotoListController",controllerAs: 'ctrPhotoList'}).state('content.photos.detail',{url: '/detail',templateUrl: 'partials/photos-detail.html',controller: 'PhotoDetailController',controllerAs: 'ctrPhotoDetail'}).state('content.photos.detail.comment',{url: '/comment',templateUrl: 'partials/photos-detail-comment.html'}).state('content.about',{url:'about',views:{"body@content":{templateUrl: 'partials/about.html'}}})
})添加controller.js,该文件用来定义所用到的controller.现在的文件结构为：
asserts/
.....css/
.....images/
..........image1.jpg
..........image2.jpg
..........image3.jpg
..........image4.jpg
node_modules/
partials/
.....about.html
.....home.html
.....photos.html
.....content.html
.....header.html
.....photos-list.html
.....photo-detail.html
.....photos-detail-comment.html
app.js
index.html
controllers.js
photoGallery.controller('HomeController',['$scope', '$state', function($scope, $state){this.message = 'Welcome to the Photo Gallery';
}]);//别名：ctrPhoto
photoGallery.controller('PhotoController',['$scope','$state', function($scope, $state){this.photos = [{ id: 0, title: 'Photo 1', description: 'description for photo 1', imageName: 'image1.jpg', comments:[{name: 'user1', comment: 'Nice'},{ name:'User2', comment:'Very good'}]},{ id: 1, title: 'Photo 2', description: 'description for photo 2', imageName: 'image2.jpg', comments:[{ name: 'user2', comment: 'Nice'},{ name:'User1', comment:'Very good'}]},{ id: 2, title: 'Photo 3', description: 'description for photo 3', imageName: 'image3.jpg', comments:[{name: 'user1', comment: 'Nice'}]},{ id: 3, title: 'Photo 4', description: 'description for photo 4', imageName: 'image4.jpg', comments:[{name: 'user1', comment: 'Nice'},{ name:'User2', comment:'Very good'},{ name:'User3', comment:'So so'}]}];//给子state下controller中的photos赋值this.pullData = function(){$scope.$$childTail.ctrPhotoList.photos = this.photos;}
}]);//别名：ctrPhotoList
photoGallery.controller('PhotoListController',['$scope','$state', function($scope, $state){this.reading = false;this.photos = new Array();this.init = function(){this.reading = true;setTimeout(function(){$scope.$apply(function(){$scope.ctrPhotoList.getData();});}, 1500);}this.getData = function(){//调用父state中controller中的方法
$scope.$parent.ctrPhoto.pullData();/*this.photos = $scope.$parent.ctrPhoto.photos;*/this.reading = false;}
}]);//别名：ctrPhotoDetail
photoGallery.controller('PhotoDetailController',['$scope', '$state', function($scope,$state){}]);以上，通过$scope.$$childTail.ctrPhotoList在父state中的controller中拿到子state中的controller；通过$scope.$parent.ctrPhoto在子state中的controller中拿到父state中的controller。
photos-list.html
<h1>photos-list</h1>
<div ng-init="ctrPhotoList.init()"><div style="margin:auto; width: 40px;" ng-if="ctrPhotoList.reading"><i class="fa fa-spinner fa-5x fa-pulse"></i></div><div class="well well-sm" ng-repeat="photo in ctrPhotoList.photos"><div class="media"><div class="media-left" style="width:15%;"><a ui-sref="content.photos.detail"><img class="img-responsive img-rounded" src="../asserts/images/{{photo.imageName}}" alt=""></a></div><div class="media-body"><h4 class="media-heading">{{photo.title}}</h4>{{photo.description}}</div></div></div>
</div>■ state间如何传路由参数
在content.photos.detail这个state设置接收一个路由参数。
.state('content.photos.detail',{url: '/detail/:id',templateUrl: 'partials/photos-detail.html',controller: 'PhotoDetailController',controllerAs: 'ctrPhotoDetail'
})photos-list.html 送出一个路由参数
<h1>photos-list</h1>
<div ng-init="ctrPhotoList.init()"><div style="margin:auto; width: 40px;" ng-if="ctrPhotoList.reading"><i class="fa fa-spinner fa-5x fa-pulse"></i></div><div class="well well-sm" ng-repeat="photo in ctrPhotoList.photos"><div class="media"><div class="media-left" style="width:15%;"><a ui-sref="content.photos.detail({id:photo.id})"><img class="img-responsive img-rounded" src="../asserts/images/{{photo.imageName}}" alt=""></a></div><div class="media-body"><h4 class="media-heading">{{photo.title}}</h4>{{photo.description}}</div></div></div>
</div>以上，通过<a ui-sref="content.photos.detail({id:photo.id})">把路由参数送出。
controller.js PhotoDetailController控制器通过$stateParams获取路由参数
...
//别名：ctrPhotoDetail
photosGallery.controller('PhotoDetailController', ['$scope', '$state', '$stateParams',function($scope, $state, $stateParams){var id = null;this.photo = null;this.init = function(){id = parseInt($stateParams.id);this.photo = $scope.ctrPhoto.photos[id];}}
]);photos-detail.html 从以上的PhotoDetailController中获取数据。
<h1>photo-details</h1>
<a class="btn btn-default" ui-sref=".comment">通过相对路径去子state</a>
<a ui-sref="content.photos.list" style="margin-left: 15px;"><i class="fa fa-arrow-circle-left fa-2x"></i>
</a><div ng-init="ctrPhotoDetail.init()"><img class="img-responsive img-rounded" ng-src="../assets/images/{{ctrPhotoDetail.photo.imageName}}"style="margin:auto; width: 60%;"><div class="well well-sm" style="margin:auto; width: 60%; margin-top: 15px;"><h4>{{ctrPhotoDetail.photo.title}}</h4><p>{{ctrPhotoDetail.photo.description}}</p></div><div style="margin:auto; width: 80%; margin-bottom: 15px;"><button style="margin-top: 10px; width:100%;"class="btn btn-default" ui-sref=".comment">Comments</button></div>
</div><div ui-view></div>■ state间如何传字符串参数
在路由中这样设置：
.state('content.photos.detail.comment',{url:'/comment?skip&limit',templateUrl: 'partials/photos-detail-comment.html',controller: 'PhotoCommentController',controllerAs: 'ctrPhotoComment'
})controllers.js 中修改如下
photoGallery.controller('HomeController',['$scope', '$state', function($scope, $state){this.message = 'Welcome to the Photo Gallery';
}]);//别名：ctrPhoto
photoGallery.controller('PhotoController',['$scope','$state', function($scope, $state){this.photos = [{ id: 0, title: 'Photo 1', description: 'description for photo 1', imageName: 'image1.JPG', comments:[{ name:'User1', comment: 'Nice', imageName: 'man.png'},{ name:'User2', comment:'Very good', imageName: 'man.png'},{ name:'User3', comment:'Nice', imageName: 'woman.png'},{ name:'User4', comment:'Very good', imageName: 'woman.png'},{ name:'User5', comment:'Very good', imageName: 'man.png'},{ name:'User6', comment:'Nice', imageName: 'woman.png'},{ name:'User7', comment:'So so', imageName: 'man.png'}]},{ id: 1, title: 'Photo 2', description: 'description for photo 2', imageName: 'image2.JPG', comments:[{ name:'User1', comment: 'Nice', imageName: 'man.png'},{ name:'User2', comment:'Very good', imageName: 'man.png'},{ name:'User3', comment:'Nice', imageName: 'woman.png'},{ name:'User4', comment:'Very good', imageName: 'woman.png'}]},{ id: 2, title: 'Photo 3', description: 'description for photo 3', imageName: 'image3.JPG', comments:[{ name:'User1', comment: 'Nice', imageName: 'man.png'},{ name:'User2', comment:'Very good', imageName: 'man.png'},{ name:'User3', comment:'Nice', imageName: 'woman.png'},{ name:'User4', comment:'Very good', imageName: 'woman.png'},{ name:'User5', comment:'Very good', imageName: 'man.png'},{ name:'User6', comment:'Nice', imageName: 'woman.png'},{ name:'User7', comment:'So so', imageName: 'man.png'}]},{ id: 3, title: 'Photo 4', description: 'description for photo 4', imageName: 'image4.JPG', comments:[{ name:'User6', comment:'Nice', imageName: 'woman.png'},{ name:'User7', comment:'So so', imageName: 'man.png'}]}];//给子state下controller中的photos赋值this.pullData = function(){$scope.$$childTail.ctrPhotoList.photos = this.photos;}
}]);//别名：ctrPhotoList
photoGallery.controller('PhotoListController',['$scope','$state', function($scope, $state){this.reading = false;this.photos = new Array();this.init = function(){this.reading = true;setTimeout(function(){$scope.$apply(function(){$scope.ctrPhotoList.getData();});}, 1500);}this.getData = function(){//调用父state中controller中的方法
$scope.$parent.ctrPhoto.pullData();/*this.photos = $scope.$parent.ctrPhoto.photos;*/this.reading = false;}
}]);//别名：ctrPhotoDetail
photoGallery.controller('PhotoDetailController', ['$scope', '$state', '$stateParams',function($scope, $state, $stateParams){var id = null;this.photo = null;this.init = function(){id = parseInt($stateParams.id);this.photo = $scope.ctrPhoto.photos[id];}}
]);photoGallery.controller('PhotoCommentController', ['$scope', '$state', '$stateParams',function($scope, $state, $stateParams){var id, skip, limit = null;this.comments = new Array();this.init = function(){id = parseInt($stateParams.id);var photo = $scope.ctrPhoto.photos[id];if($stateParams.skip){skip = parseInt($stateParams.skip);}else{skip = 0;}if($stateParams.limit){limit = parseInt($stateParams.limit);}else{limit = photo.comments.length;}this.comments = photo.comments.slice(skip, limit);}}
]);也就是，$stateParams不仅可以接收路由参数，还可以接收查询字符串参数。
photo-detail.html 需要把查询字符串参数传递出去
<h1>photo-details</h1>
<a class="btn btn-default" ui-sref=".comment">通过相对路径去子state</a>
<a ui-sref="content.photos.list" style="margin-left: 15px;"><i class="fa fa-arrow-circle-left fa-2x"></i>
</a><div ng-init="ctrPhotoDetail.init()"><img class="img-responsive img-rounded" ng-src="../assets/images/{{ctrPhotoDetail.photo.imageName}}"style="margin:auto; width: 60%;"><div class="well well-sm" style="margin:auto; width: 60%; margin-top: 15px;"><h4>{{ctrPhotoDetail.photo.title}}</h4><p>{{ctrPhotoDetail.photo.description}}</p></div><div style="margin:auto; width: 80%; margin-bottom: 15px;"><button style="margin-top: 10px; width:100%;"class="btn btn-default" ui-sref=".comment({skip:0, limit:2})">Comments</button></div>
</div><div ui-view></div>以上，通过ui-sref=".comment({skip:0, limit:2})把查询字符串传递出去。
photos-detail-comment.html
<h1>photos-detail-comment</h1><div ng-init="ctrPhotoComment.init()" style="margin-top:15px;"><div ng-repeat="comment in ctrPhotoComment.comments" class="well well-sm" style="margin: auto; width: 60%;"><div class="media"><div class="media-left media-middle"><a href=""><img class="img-circle" style="width:60px;" src="../assets/images/{{comment.imageName}}" alt=""></a></div><div class="media-body"><h4 class="media-heading">{{comment.name}}</h4>{{comment.comment}}</div></div></div>
</div>■ state间如何传递对象
通过data属性，把一个对象赋值给它。
.state('content',{url: '/',abstract: true,data:{user: "user",password: "1234"},views:{"":{templateUrl: 'partials/content.html'},"header@content":{templateUrl: 'partials/header.html'},}
})给header.html加上一个对应的控制器，并提供注销方法。
$stateProvider.state('content',{url: '/',abstract: true,data:{user: "user",password: "1234"},views:{"":{templateUrl: 'partials/content.html'},"header@content":{templateUrl: 'partials/header.html',controller: function($scope, $rootScope, $state){$scope.logoff = function(){$rootScope.user = null;}}}}})添加一个有关登录页的state
.state('content.login',{url:'login',data:{loginError: 'User or password incorrect.'},views:{"body@content" :{templateUrl: 'partials/login.html',controller: function($scope, $rootScope, $state){$scope.login = function(user, password, valid){if(!valid){return;}if($state.current.data.user === user && $state.current.data.password === password){$rootScope.user = {name: $state.current.data.user}// Or Inherited/*$rootScope.user = {name: $state.$current.parent.data.user};*/$state.go('content.home'); }else{$scope.message = $state.current.data.loginError;}}}}}})添加login.html文件，现在的文件结构为：

..........image4.jpg
node_modules/
partials/
.....about.html

</form>header.html 修改如下
<nav class="navbar navbar-inverse"><div class="container-fluid"><div class="navbar-header"><button class="navbar-toggle collapsed" type="button" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> <span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span></button><a class="navbar-brand" ui-sref="content.home">Home</a></div><div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"><ul class="nav navbar-nav"><li><a ui-sref="content.photos.list">Photos</a> </li><li><a ui-sref="content.about">About</a> </li> </ul><ul class="nav navbar-nav navbar-right"> <li ng-if="user.name" class="dropdown"><a class="dropdown-toggle" role="button" aria-expanded="false" href="#" data-toggle="dropdown">{{user.name}} <span class="caret"></span></a><ul class="dropdown-menu" role="menu"><li><a ui-sref="content.home" ng-click="logoff()">Sing out</a></li> </ul> </li> <li ng-if="!user.name"><a ui-sref="content.login">Sing In</a></li> </ul> </div></div></nav>■ onEnter和onExit事件
.state('content.photos.detail',{url: '/detail/:id',templateUrl: 'partials/photos-detail.html',controller: 'PhotoDetailController',controllerAs: 'ctrPhotoDetail',resolve:{viewing: function($stateParams){return{photoId: $stateParams.id}}},onEnter: function(viewing){var photo = JSON.parse(sessionStorage.getItem(viewing.photoId));if(!photo){photo = {views: 1,viewing: 1}}else{photo.views = photo.views + 1;photo.viewing = photo.viewing + 1;}sessionStorage.setItem(viewing.photoId, JSON.stringify(photo));},onExit: function(viewing){var photo = JSON.parse(sessionStorage.getItem(viewing.photoId));photo.viewing = photo.viewing - 1;sessionStorage.setItem(viewing.photoId, JSON.stringify(photo));}
})在PhotoDetailController中：
photoGallery.controller('PhotoDetailController', ['$scope', '$state', '$stateParams',function($scope, $state, $stateParams){var id = null;this.photo = null;this.viewObj = null;this.init = function(){id = parseInt($stateParams.id);this.photo = $scope.ctrPhoto.photos[id];this.viewObj = JSON.parse(sessionStorage.getItem($stateParams.id));}}
]);photos-detail.html
<h1>photo-details</h1>
<a class="btn btn-default" ui-sref=".comment">通过相对路径去子state</a>
<a ui-sref="content.photos.list" style="margin-left: 15px;"><i class="fa fa-arrow-circle-left fa-2x"></i>
</a><div ng-init="ctrPhotoDetail.init()"><img class="img-responsive img-rounded" ng-src="../assets/images/{{ctrPhotoDetail.photo.imageName}}"style="margin:auto; width: 60%;"><div class="well well-sm" style="margin:auto; width: 60%; margin-top: 15px;"><div class="well well-sm pull-right" style="width: 100px;"><i>Views <span class="badge">{{ctrPhotoDetail.viewObj.views}}</span></i></div><div class="well well-sm pull-right" style="width: 110px;"><i>Viewing <span class="badge">{{ctrPhotoDetail.viewObj.viewing}}</span></i></div><h4>{{ctrPhotoDetail.photo.title}}</h4><p>{{ctrPhotoDetail.photo.description}}</p></div><div style="margin:auto; width: 80%; margin-bottom: 15px;"><button style="margin-top: 10px; width:100%;"class="btn btn-default" ui-sref=".comment({skip:0, limit:2})">Comments</button></div>
</div><div ui-view></div>■ StateChangeStart事件
controller.js 增加如下
photoGallery.controller('RootController', ['$scope', '$state', '$rootScope',function($scope, $state, $rootScope){$rootScope.$on('$stateChangeStart',function(event, toState, toParams, fromState, fromParams){if(toState.data.required && !$rootScope.user){event.preventDefault();$state.go('content.login');}});}
]);修改content这个state:
.state('content',{url:'/',abstract: true,data:{user: "user",password: "1234"},views:{"":{templateUrl: 'partials/content.html',controller: 'RootController'},"header@content":{templateUrl: 'partials/header.html',controller: function($scope, $rootScope, $state){$scope.logoff = function(){$rootScope.user = null;}}}}})content.photos.detail这个state
.state('content.photos.detail',{url:'/detail/:id',templateUrl: 'partials/photos-detail.html',controller: 'PhotoDetailController',controllerAs: 'ctrPhotoDetail',data:{required: true},resolve:{viewing: function($stateParams){return{photoId: $stateParams.id}}},onEnter: function(viewing){var photo = JSON.parse(sessionStorage.getItem(viewing.photoId));if(!photo){photo = {views: 1,viewing: 1}}else{photo.views = photo.views + 1;photo.viewing = photo.viewing + 1;}sessionStorage.setItem(viewing.photoId, JSON.stringify(photo));},onExit: function(viewing){var photo = JSON.parse(sessionStorage.getItem(viewing.photoId));photo.viewing = photo.viewing - 1;sessionStorage.setItem(viewing.photoId, JSON.stringify(photo));}})以上，添加了
data:{
required: true
}
同理，content.photos.detail.comment这个state
.state('content.photos.detail.comment',{url:'/comment?skip&limit',templateUrl: 'partials/photos-detail-comment.html',controller: 'PhotoCommentController',controllerAs: 'ctrPhotoComment',data:{required: true}})■ StateNotFound事件
photosGallery.controller('RootController', ['$scope', '$state', '$rootScope',function($scope, $state, $rootScope){$rootScope.$on('$stateChangeStart', function(event, toState, toParams, fromState, fromParams){if(toState.data.required && !$rootScope.user){event.preventDefault();$state.go('content.login');return;} });$rootScope.$on('$stateNotFound', function(event, unfoundState, fromState, fromParams){event.preventDefault();$state.go('content.notfound');});}
]);添加一个state:
.state('content.notfound',{url:'notfound',views: {"body@content": {templateUrl: 'partials/page-not-found.html'} } })page-not-found.html
<div class="well well-sm" style="margin: 20px;"><i class="fa fa-frown-o fa-4x pull-left"></i><h3>404 - Sorry! Not found your page.</h3> </div>
■ StateChangeSuccess事件
photosGallery.controller('RootController', ['$scope', '$state', '$rootScope',function($scope, $state, $rootScope){$rootScope.accessLog = new Array();$rootScope.$on('$stateChangeStart', function(event, toState, toParams, fromState, fromParams){if(toState.data.required && !$rootScope.user){event.preventDefault();$state.go('content.login');return;} });$rootScope.$on('$stateNotFound', function(event, unfoundState, fromState, fromParams){event.preventDefault();$state.go('content.notfound');});$rootScope.$on('$stateChangeSuccess', function(event, toState, toParams, fromState, fromParams){$rootScope.accessLog.push({user: $rootScope.user,from: fromState.name,to: toState.name,date: new Date()});});}
]);添加一个state
.state('content.log',{url:'log',data:{required: true},views: {"body@content": {templateUrl: 'partials/log.html'} } })log.html
<h1><i class="fa fa-file-text-o"></i> Access Log</h1>
<div style="margin:auto; width: 380px;"><div class="well well-sm" ng-repeat="log in accessLog track by $index"><i class="fa fa-pencil fa-2x pull-left"></i>{{log.user ? log.user.name: 'anonymous'}} in {{log.date | date: 'longDate'}} at {{log.date | date: 'shortTime'}}<p>From: {{log.from}} => to: {{log.to}}</p></div>
</div>■ StateChangeError事件
photosGallery.controller('RootController', ['$scope', '$state', '$rootScope',function($scope, $state, $rootScope){$rootScope.accessLog = new Array();$rootScope.$on('$stateChangeStart', function(event, toState, toParams, fromState, fromParams){if(toState.data.required && !$rootScope.user){event.preventDefault();$state.go('content.login');return;} });$rootScope.$on('$stateNotFound', function(event, unfoundState, fromState, fromParams){event.preventDefault();$state.go('content.notfound');});$rootScope.$on('$stateChangeSuccess', function(event, toState, toParams, fromState, fromParams){$rootScope.accessLog.push({user: $rootScope.user,from: fromState.name,to: toState.name,date: new Date()});});$rootScope.$on('$stateChangeError', function(event, toState, toParams, fromState, fromParams, error){event.preventDefault();$state.go('content.error', {error: error});});}
]);添加2个state:
.state('content.profile', {url:'profile',data:{required: true},resolve:{showError: function(){throw 'Error in code.';}},views:{"body@content": {template: '<div>Error</div>'}} }).state('content.error',{url:'error/:error',views:{"body@content":{templateUrl: 'partials/error.html',controller: function($scope, $stateParams){$scope.error = {message: $stateParams.error}}}}}) error.html
<div class="well well-sm" style="margin: 20px;"><i class="fa fa-exclamation-circle fa-2x"> Sorry! But this message was displayed: {{error.message}}</i>
