Angularjs中UI Router全攻略

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

<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:

<div ui-view="header"></div>
<div ui-view="body"></div>

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');


.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:

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
.....login.html

app.js

index.html

login.html

<form name="form" ng-submit="login(user, password, form.$valid)">
<div class="panel panel-primary" style="width:360px; margin: auto;">
<div class="panel-heading">
<h3 class="panel-title">Indentification</h3>
</div>
<div class="panel-body">
<input name="user" type="text" class="form-control" ng-model="user" placeholder="User ..." required>
<span ng-show="form.user.$error.required && form.user.$dirty" class="label label-danger">Enter the user</span>
<hr>
<input name="password" type="password" class="form-control" ng-model="password" placeholder="Password ..." required>
<span ng-show="form.password.$error.required && form.password.$dirty" class="label label-danger">Enter the password</span> 
</div>
<div class="panel-footer">
<button class="btn btn-default" type="submit">Login</button>
<button class="btn btn-default" type="reset">Reset</button>
<span class="label label-danger">{{message}}</span> 
</div> 
</div>
</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:

</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){

<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.accessLog.push({
user: $rootScope.user,
from: fromState.name,

});
});
$rootScope.$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>
</div>
