javascript - 如何使用 ng-switch 作为我的页面的路由器 ngRoute 和 ngView？

Question

这是我的 Angular SPA 的高级框架。我的申请是关于大学学位类(class)的。在该工程页面中有一个单独的左侧导航，当前构建在 ng-switch 上，我想将其转换为路线。我如何仅使用 Angular 的 native 路由 Angular-route.js 来做到这一点？

**app.js**
(function(){
   var app=angular.module("myCollege",['ngRoute']);

   app.config(['$routeProvider','$locationProvider',  
          function($routeProvider,$locationProvider) {

            $routeProvider 

                 .when('/', {
                       templateUrl:"app/views/home.html",
                       controller:"homeController",
                       }

                    .when('/engg', {
                       templateUrl:"app/views/engineering.html",
                       controller:"engineeringController",
                       })
                    .when('/med', {
                       templateUrl:"app/views/medical.html",
                       controller:"medicalController",
                       })

                  }]);

I have left nav in engineering.html using ng-switch which i want to convert as sub-route of the application.This left nav of engineering page is not inside of ngView. How do i acheive this using angular's native ngRoute/angular-route?

**engineering.html**

<div nav ng-switch on="pagename()">
        <div ng-switch-when="Civil Engineering">
               <div civil-directive> </div>
         </div>
         <div ng-switch-when="Computer Engineering">
               <div computer-directive> </div>
         </div>
         <div ng-switch-when="Nano Engineering">
               <div nano-directive> </div>
         </div>
         <div ng-switch-when="Electrical Engineering">
               <div electrical-directive> </div>
         </div>
     </div>

EngineeringController.js

(function() {
var app =angular.module("collegeApp");
var engineeringController= functino($scope,$rootscope,$location)

 {

   $scope.pagename = function() {
      return $location.path();
   };
app.controller("engineeringController",['$scope','$rootScope','$location',engineeringController])
}());

以上逻辑对我来说不起作用。有人可以告诉我哪里做错了吗？

这不是一个好的做法，但如果你想使用 ng-switch，这就是你想要做的:

在您的html中，例如您所写的:

<!-- don't forget to reference your app and your controller -->
<button ng-click="goTo('/page1')">Go to page 1</button>
<button ng-click="goTo('/page2')">Go to page 2</button>
<div nav ng-switch on="pagename()">
     <div ng-switch-when="'/page1'"></div>
     <div ng-switch-when="'/page2'"></div>
</div>
<div ng-view> </div> 

在js中

Config your routes
app.config(['$routeProvider',
    function($routeProvider) {
        $routeProvider.
            when('/page1', {
                templateUrl: 'views/page1.html'
            }).
            when('/page2', {
                templateUrl: 'views/page2.html'
            }).
            otherwise({
                redirectTo: '/'
            });
    }])

并在 Controller 中添加以下内容:

$scope.pagename = function() { return $location.path(); };

    $scope.goTo = function(page){
        $location.path(page);
    }

在上面的 html 中，ng-switch 将使用 $location.path() 变量来知道要显示哪个 View 。

正如我所说，这不是一个好的做法，因为您的 Controller 不应该处理路由。
