angularjs:在模板

在加载'/'时,我得到'内容'和'侧边栏'使用'myService'并解决路由提供程序中的选项,我可以将'内容'呈现给模板($ scope.contents = content;)。

  

但$ scope.sideBar = sideBar;不管用。这是因为sideBar在模板之外?

     

如何在加载'/'时呈现侧边栏项?是否可以将此数据(侧边栏)传递给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'    
    }    
});

的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();
});

首次初始化indexCtrl时,这将从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;
});

并在index.html内部:

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

当服务中的数据更新时,字符串将更新。
