angularjs: 在模板外获取路由解析数据

Question

加载“/”时，我使用 'myService' 获取 'content' 和“侧边栏”，并在路由提供程序中解析选项，我可以将 'content' 渲染到模板 ($ scope.contents = 内容；）。

But $scope.sideBar = sideBar; is not working. This is because sideBar is outside the template ?

How can I render sidebar items on loading '/' ? Is it possible to pass this data (sidebar) to the indexCtrl?

app.js

var myApp = angular.module("MyApp", ['ngRoute']);

myApp.config(['$routeProvider',
  function($routeProvider) {
    $routeProvider.
      when('/', {
        templateUrl: 'contents.html',
        controller: 'Myctrl',
        resolve: {
            content: function(myService){
                return myService.getContent();
            },
            sideBar: function(myService){
                return myService.getSideBar();            
            }    
          }           
      }).
      otherwise({
        redirectTo: '/'
      });
}]);


myApp.controller('Myctrl', function (content, sideBar, $scope) {    
    $scope.contents = content;
    $scope.sideBar = sideBar;
});

myApp.controller('indexCtrl', function($scope) { 


});


myApp.service("myService", function () {     
    this.getContent = function () {
       return 'Main contents';
    }    

    this.getSideBar = function () {
       return 'side bar'    
    }    
});

index.html

<div ng-app="MyApp" ng-controller="indexCtrl">

            <div class="sidebar">
                {{sideBar}}
            </div>        

            </div>
            <div class="main">                      
                    <div ng-view></div> 
            </div> 
</div>

contents.html

<div>{{contents}}</div>

您可以将 myService 注入 indexCtrl 并像这样访问函数 getSideBar

myApp.controller('indexCtrl', function($scope, myService) { 

 $scope.sideBar = myService.getSideBar();
});

这将在您的 indexCtrl 首次初始化时从您的 getSideBar 函数中获取字符串。如果你这样做：

myApp.controller('indexCtrl', function($scope, myService) { 

 $scope.sideBar = myService.getSideBar;
});

和内部 index.html:

 <div class="sidebar">
     {{sideBar()}}
 </div>

该字符串将在您服务中的数据更新时更新。
