我想使用 ngroute 模块在同一页面中使用不同主题路由我的应用程序，使用此示例:

<html>
   
   <head>
      <title>Angular JS Views</title>
      <script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
      <script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular-route.min.js"></script>
   </head>
   
   <body>
      <h2>AngularJS Sample Application</h2>
      <div ng-app = "mainApp">
         <p><a href = "#addStudent">Add Student</a></p>
         <p><a href = "#viewStudents">View Students</a></p>
         <div ng-view></div>
         
         <script type = "text/ng-template" id = "addStudent.htm">
            <h2> Add Student </h2>
            {{message}}
         </script>
         
         <script type = "text/ng-template" id = "viewStudents.htm">
            <h2> View Students </h2>
            {{message}}
         </script>
      </div>
      
      <script>
         var mainApp = angular.module("mainApp", ['ngRoute']);
         mainApp.config(['$routeProvider', function($routeProvider) {
            $routeProvider.
            
            when('/addStudent', {
               templateUrl: 'addStudent.htm',
               controller: 'AddStudentController'
            }).
            
            when('/viewStudents', {
               templateUrl: 'viewStudents.htm',
               controller: 'ViewStudentsController'
            }).
            
            otherwise({
               redirectTo: '/addStudent'
            });
         }]);
         
         mainApp.controller('AddStudentController', function($scope) {
             console.log("adssadsd");
            $scope.message = "This page will be used to display add student form";
         });
         
         mainApp.controller('ViewStudentsController', function($scope) {
            $scope.message = "This page will be used to display all the students";
         });
			
      </script>
      
   </body>
</html>

在此示例中，在同一页面中路由不同的主题: enter image description here

这样。在我的应用程序中尝试:html文件:

app.config(['$routeProvider', function($routeProvider) {
            $routeProvider.
            
            when('/sessionexpired', {
               templateUrl: 'addStudent.htm',
               controller: 'AddStudentController'
            }).
            
            when('/viewStudents', {
               templateUrl: 'viewStudents.htm',
               controller: 'ViewStudentsController'
            }).
            
            otherwise({
               redirectTo: '/addStudent'
            });
         }]);

app.controller('AddStudentController', function($scope) {
        console.log("ciao");
            $scope.message = "This page will be used to display add student form";
         });
         
         app.controller('ViewStudentsController', function($scope) {
               console.log("ciao");
            $scope.message = "This page will be used to display all the students";
         });

在 js 文件中，我放置了我的 Controller 和我的配置:

app.config(['$routeProvider', function($routeProvider) {
            $routeProvider.
            
            when('/sessionexpired', {
               templateUrl: 'addStudent.htm',
               controller: 'AddStudentController'
            }).
            
            when('/viewStudents', {
               templateUrl: 'viewStudents.htm',
               controller: 'ViewStudentsController'
            }).
            
            otherwise({
               redirectTo: '/addStudent'
            });
         }]);

app.controller('AddStudentController', function($scope) {
        console.log("ciao");
            $scope.message = "This page will be used to display add student form";
         });
         
         app.controller('ViewStudentsController', function($scope) {
               console.log("ciao");
            $scope.message = "This page will be used to display all the students";
         });

我也尝试过 console.log("ciao"); ，但是当我尝试这个 url 时:file:///C:/Users/Giacomo%20B/Desktop/progetto%20mainetti/prove%20angular/fddWebapp/login.html#/viewStudents 什么也没有出现，console.log 也没有: enter image description here

问题在哪里？为什么我的 Controller 不起作用？

最佳答案

我看到几个问题:

  1. 你没有 <div ng-view></div>在您的 html 页面中标记
  2. 您已重定向到 '/addStudent' ，但您没有配置此路由(我想 '/sessionexpired' 应该重命名为它)
  3. 您已声明 ng-controller="LoginController"两次，我想最后一次就够了。

关于javascript - Angular ngroute : controllers doesnt's work，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41193836/
