首先给大家介绍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


$stateProvider.state("home",{
template: "hi"
})

或者这样配置：

$stateProvider.state("home"{
views: {
"": {
template: "hi"
}
}
})

==有名称的ui-view


$stateProvider.state("home",{
views: {
"main" : {
template: "hi"
}
}
})

==多个ui-view



$stateProvider.state("home",{
views: {
"":{template: "hi"},
"data": {template: "data"}
}
})

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



Welcome

state之间的跳转

index.html




Home




Photos


About

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：

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：

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

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

header.html 把原先indext.html中nav部分放到这里来




Home




Photos


About

index.html 这时变成了这样

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

.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

，就加载如下：

"header@content":{templateUrl: 'partials/header.html'},

看到

，先加载 "body@content":{templateUrl: 'partials/home.html'}

→ 点击header上的链接

点击Photos，来到：

.state('content.photos',{
url: 'photos',
views:{
"body@content":{templateUrl: 'partials/photos.html'}
}
})

把partials/photos.html显示到

中去。

点击

，来到：

.state('content.about',{
url:'about',
views:{
"body@content":{templateUrl: 'partials/about.html'}
}
})

把partials/about.html显示到

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

如何到达这个子页面呢？修改header中的相关部分如下：




Home




Photos


About

以上，通过Photos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

photos-list

photo-detail.html 又提供了来到其子页面photos-detail-comment.html的ui-view

photo-details
通过相对路径去子state

photos-detail-comment.html 则很简单：

photos-detail-comment

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

photos-list











{{photo.title}}
{{photo.description}}

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

photos-list











{{photo.title}}
{{photo.description}}

以上，通过把路由参数送出。

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。

photo-details
通过相对路径去子state





{{ctrPhotoDetail.photo.title}}
{{ctrPhotoDetail.photo.description}}

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

photo-details
通过相对路径去子state





{{ctrPhotoDetail.photo.title}}
{{ctrPhotoDetail.photo.description}}

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

photos-detail-comment








{{comment.name}}
{{comment.comment}}

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：

app.js

index.html

header.html 修改如下




Home




Photos 


About 
 



{{user.name}} 

Sing out 

 

Sing In

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

photo-details
通过相对路径去子state






Views {{ctrPhotoDetail.viewObj.views}}


Viewing {{ctrPhotoDetail.viewObj.viewing}}

{{ctrPhotoDetail.photo.title}}
{{ctrPhotoDetail.photo.description}}

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


404 - Sorry! Not found your page.

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


 Access Log



{{log.user ? log.user.name: 'anonymous'}} in {{log.date | date: 'longDate'}} at {{log.date | date: 'shortTime'}}
From: {{log.from}} => to: {{log.to}}

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: 'Error'}
} 
})
.state('content.error',{
url:'error/:error',
views:{
"body@content":{
templateUrl: 'partials/error.html',
controller: function($scope, $stateParams){
$scope.error = {
message: $stateParams.error
}
}
}
}
})

error.html
