我是Ionic和AngularJS的新手。我试图创建一个应用程序,但似乎app.js的内容是错误的。

这是我的代码:

app.js

angular.module('starter', ['ionic', 'starter.controllers'])
.config(function($stateProvider, $urlRouterProvider) {
  $stateProvider.state('app', {
    url: "/ListeUsers",
    views: {
          templateUrl: "templates/ListeUsers.html",
          controller: 'UsersCtrl'
    }
});
  // if none of the above states are matched, use this as the fallback
$urlRouterProvider.otherwise('/app/ListeUsers');
});

的index.html

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
    <title></title>

    <link href="lib/ionic/css/ionic.css" rel="stylesheet">
    <link href="css/style.css" rel="stylesheet">

    <!-- IF using Sass (run gulp sass first), then uncomment below and remove the CSS includes above
    <link href="css/ionic.app.css" rel="stylesheet">
    -->

    <!-- ionic/angularjs js -->
    <script src="lib/ionic/js/ionic.bundle.js"></script>
	<script src="lib/ionic/js/angular/angular-resource.min.js"></script>

    <!-- cordova script (this will be a 404 during development) -->
    <script src="cordova.js"></script>

    <!-- your app's js -->
    <script src="js/app.js"></script>
    <script src="js/UserControllerIonic.js"></script>
	<script src="js/UsersServiceIonic.js"></script>
  </head>

  <body ng-app="starter">
    <ion-nav-view></ion-nav-view>
	
  </body>
</html>

userControllerIonic.js

angular.module('starter.controllers', ['starter.services'])



.controller('UsersCtrl', function($scope,userService) {
	
	
	$scope.Users=userService.getUsers();
	
});

UsersServiceIonic.js

angular.module('starter.services', ['ngResource'])


.factory('userService',function () {

		var Users =[];
        
        return{
			
			getUsers:function(){
				return $http.get("http://localhost:26309/api/User/getAll/").then(function (response) {
							users=response;
                            return users;
                        });
			},
			
			getUser : function(UserName) {
				return $http.get("http://localhost:26309/api/User/getUserByNom/" + UserName).then(function (serviceResp) {
					return serviceResp.data;
				});
			}
		}
		
})

ListeUsers.html

    <ion-list>
      <ion-item ng-repeat="user in Users"
               >{{user.nom}}</ion-item>
    </ion-list>
  

我找不到问题

答案 0 :(得分:1)

您需要在此处修复2个问题才能使您的应用正常运行:

  1. 您需要将默认回退网址从/app/ListeUsers更正为/ListeUsers,因为/app/ListeUsers路径在状态为app的子状态时有效。在此处查看更多详细信息:https://github.com/angular-ui/ui-router/wiki/Nested-States-and-Nested-Views

  2. 您的服务方法正在返回承诺。 您无法为$ scope变量分配承诺,并希望该应用正常运行。更改控制器代码以使用返回的promise的.then方法回调中的参数,如下所示:

    角    .module('starter.controllers',['starter.services'])    .controller('UsersCtrl',function($ scope,userService){
          userService.getUsers()         .then(function(response){           $ scope.Users = response;         });     });
