angularJS $routeProvider

 

O'Reilly書上的偽代碼

var someModule = angular.module('someModule',[...module dependencies]);

someModule.config(function($routeProvider){
    $routeProvider
        .when('url',{controller:aController, templateUrl:'/path/to/template'})
        .when(...)//other mappings for your app
        .otherwise(...)//what to do if nothing else matches
});

 

$route被用於URLS到controller和view(HTML模板)之間的鏈接，它會監控$location.url()並試圖對此路徑及對應的路由配置進行映射，使用時需要注入安裝ngroute模塊。

var someModule = angular.module('someModule',['ngRoute']);

舉個詳細的栗子

var app = angular.module('app', ['ngRoute']);
    app.config(function ($routeProvider){
        $routeProvider
            .when('/other', {
                controller: 'otherCtrl',
                templateUrl: 'content/views/other.html',
                publicAccess: true
            })
            .when('/', {
                controller: 'homeCtrl',
                templateUrl: 'content/views/home.html'
            })
            .when('/other/：id', {
                controller: 'otherDetailCtrl',
                templateUrl: 'content/views/otherDetail.html',
                publicAccess: true
            })
            .otherwise({
                redirectTo: '/'
            });
    }


app.controller('homeCtrl',function($scope,$http){
    console.log('i am home page');
    $scope.title = 'i am home page';
});

app.controller('otherCtrl',function($scope){
    console.log('i am other page');
    $scope.title = 'i am other page';
});

app.controller('otherDetailCtrl',function($scope, $routeParams, $location){
    var id = $routeParams.id;
    if(id == 0) {
        $location.path('/other');
    }
    console.log('i am otherDetailCtrl page');
    $scope.title = 'i am otherDetailCtrl page';
});

在$route(路由)中，提供了兩個依賴性服務：$location、$routeParams。

$location、$routeParams均可在controller中使用，如上otherDetailCtrl中，可通過$routeParams獲取路由時所傳參數，可通過$location進行路由跳轉。
