本系列探寻AngularJS的路由机制，在WebStorm下开发。主要包括：
● 路由的Big Picture
● $routeProvider配置路由
● 使用template属性
● 使用templateUrl属性
● redirectTo属性，接受字符串
● redirectTo属性，接受函数
● 使用caseInsensitiveMatch属性，禁止大小写敏感
● 使用otherwise属性

获取ngRoute模块
bower install angular-route#1.4.0
或
npm install [email protected]
或
http://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular-route.js
或
https://code/angularjs.org/1.4.0/angular-route.js
如何使用呢？
在项目中引用angular-route.js,设置对ngRoute这个module的依赖(var app = angular.module(‘app‘,[‘ngRoute‘]))，在视图中添加ng-view这个directive(<div ng-view></div>)。
Big Picture
在了解路由之前，有必要知道路由在整个AnuglarJS中所扮演的角色，如下：
$routeProvider配置路由
大致按如下配置：
(function(){
var app = angular.module(‘app‘,[‘ngRoute‘]);
app.config([‘$routeProvider‘, function($routeProvider){
$routeProvider
.when(‘/‘,{
controller: ‘HomeController‘,
contrllerAs: ‘home‘,
templateUrl: ‘app/templates/home.html‘
});
}])
}());
■ index.html

toastr.min.css

<body ng-app="app">

<a href="#/schools">Schools</a>
<a href="#/classrooms">Classrooms</a>
<a href="#/activities">Activities</a>
<div ng-view></div>
</body>
app.js，第一次添加路由，使用template属性
(function(){
var app = angular.module(‘app‘, [‘ngRoute‘]);
app.config([‘$logProvider‘,‘$routeProvider‘, function($logProvider,$routeProvider){
$logProvider.debugEnabled(true);
$routeProvider
.when(‘/‘,{
controller: ‘HomeController‘ ,
controllerAs: ‘home‘,
template: ‘<h1>This is an inline template</h1>‘
});
}]);
}());
app.js,使用templateUrl属性
(function(){
var app = angular.module(‘app‘, [‘ngRoute‘]);
app.config([‘$logProvider‘,‘$routeProvider‘, function($logProvider,$routeProvider){
$logProvider.debugEnabled(true);
$routeProvider
.when(‘/‘,{
controller: ‘HomeController‘ ,
controllerAs: ‘home‘,
templateUrl: ‘/app/templates/home.html‘
});
}]);
}());
■ home.html
{{home.message}}
{{home.schoolCount}}
{{home.activityCount}}
■ app.js,添加更多的路由
(function(){
var app = angular.module(‘app‘, [‘ngRoute‘]);
app.config([‘$logProvider‘,‘$routeProvider‘, function($logProvider,$routeProvider){
$logProvider.debugEnabled(true);
$routeProvider
.when(‘/‘,{
controller: ‘HomeController‘ ,
controllerAs: ‘home‘,
templateUrl: ‘/app/templates/home.html‘
})
.when(‘/schools‘,{
controller: ‘AllSchoolsController‘,
controllerAs: ‘schools‘,
templateUrl: ‘/app/templates/allSchools.html‘
})
.when(‘/classrooms‘,{
controller: ‘AllClassroomsController‘,
controllerAs: ‘classrooms‘,
templateUrl: ‘/app/templates/allClassrooms.html‘
})
.when(‘/activities‘,{
controller: ‘AllActivitiesController‘,
controllerAs: ‘activities‘,
templateUrl: ‘/app/templates/allActivities.html‘
});
}]);
}());
点击导航栏上的Schools
点击导航栏上的Classrooms
点击导航栏上的Activities
app.js, 添加redirectTo属性,接受字符串
(function(){
var app = angular.module(‘app‘, [‘ngRoute‘]);
app.config([‘$logProvider‘,‘$routeProvider‘, function($logProvider,$routeProvider){
$logProvider.debugEnabled(true);
$routeProvider
.when(‘/‘,{
controller: ‘HomeController‘ ,
controllerAs: ‘home‘,
templateUrl: ‘/app/templates/home.html‘
})
.when(‘/schools‘,{
controller: ‘AllSchoolsController‘,
controllerAs: ‘schools‘,
templateUrl: ‘/app/templates/allSchools.html‘
})
.when(‘/classrooms‘,{
controller: ‘AllClassroomsController‘,
controllerAs: ‘classrooms‘,
templateUrl: ‘/app/templates/allClassrooms.html‘,
redirectTo: ‘/schools‘
})
.when(‘/activities‘,{
controller: ‘AllActivitiesController‘,
controllerAs: ‘activities‘,
templateUrl: ‘/app/templates/allActivities.html‘
});
}]);
}());
点击Classrooms导航到Schools下
app.js, 添加redirectTo,接受函数
(function(){
var app = angular.module(‘app‘, [‘ngRoute‘]);
app.config([‘$logProvider‘,‘$routeProvider‘, function($logProvider,$routeProvider){
$logProvider.debugEnabled(true);
$routeProvider
.when(‘/‘,{
controller: ‘HomeController‘ ,
controllerAs: ‘home‘,
templateUrl: ‘/app/templates/home.html‘
})
.when(‘/schools‘,{
controller: ‘AllSchoolsController‘,
controllerAs: ‘schools‘,
templateUrl: ‘/app/templates/allSchools.html‘
})
.when(‘/classrooms/:id‘,{
controller: ‘AllClassroomsController‘,
controllerAs: ‘classrooms‘,
templateUrl: ‘/app/templates/allClassrooms.html‘,
redirectTo: function(params, currPath, currSearch){
console.log(params);
console.log(currPath);
console.log(currSearch);
return ‘/‘;
}
})
.when(‘/activities‘,{
controller: ‘AllActivitiesController‘,
controllerAs: ‘activities‘,
templateUrl: ‘/app/templates/allActivities.html‘
});
}]);
}());
在浏览器输入：localhost:3000/#/classrooms/1?foo=bar
可见，路由参数1被放在了params中，是一个object对象；/classrooms/1被放在了currPath中；foo=bar查询字符串被放在了currSearch中了，是一个object对象。
app.js, 禁止大小写敏感，使用caseInsensitiveMatch属性
(function(){
var app = angular.module(‘app‘, [‘ngRoute‘]);
app.config([‘$logProvider‘,‘$routeProvider‘, function($logProvider,$routeProvider){
$logProvider.debugEnabled(true);
$routeProvider
.when(‘/‘,{
controller: ‘HomeController‘ ,
controllerAs: ‘home‘,
templateUrl: ‘/app/templates/home.html‘
})
.when(‘/schools‘,{
controller: ‘AllSchoolsController‘,
controllerAs: ‘schools‘,
templateUrl: ‘/app/templates/allSchools.html‘,
caseInsensitiveMatch: true
})
.when(‘/classrooms/:id‘,{
controller: ‘AllClassroomsController‘,
controllerAs: ‘classrooms‘,
templateUrl: ‘/app/templates/allClassrooms.html‘
})
.when(‘/activities‘,{
controller: ‘AllActivitiesController‘,
controllerAs: ‘activities‘,
templateUrl: ‘/app/templates/allActivities.html‘
});
}]);
}());
localhost:3000/#/schools和localhost:3000/#/SCHOOLS能得到相同的结果。
app.js, 当用户输入的uri无效导航到默认页,使用otherwise属性
(function(){
var app = angular.module(‘app‘, [‘ngRoute‘]);
app.config([‘$logProvider‘,‘$routeProvider‘, function($logProvider,$routeProvider){
$logProvider.debugEnabled(true);
$routeProvider
.when(‘/‘,{
controller: ‘HomeController‘ ,
controllerAs: ‘home‘,
templateUrl: ‘/app/templates/home.html‘
})
.when(‘/schools‘,{
controller: ‘AllSchoolsController‘,
controllerAs: ‘schools‘,
templateUrl: ‘/app/templates/allSchools.html‘,
caseInsensitiveMatch: true
})
.when(‘/classrooms/:id‘,{
controller: ‘AllClassroomsController‘,
controllerAs: ‘classrooms‘,
templateUrl: ‘/app/templates/allClassrooms.html‘
})
.when(‘/activities‘,{
controller: ‘AllActivitiesController‘,
controllerAs: ‘activities‘,
templateUrl: ‘/app/templates/allActivities.html‘
})
.otherwise(‘/‘);
}]);
}());
