$範圍值未更新側面菜單

我堅持的一個問題在我的離子應用具有與name和picture邊欄菜單與它的父和abstract:true。在同一控制器中，有一個更新功能，它更新scope.picture，但側面菜單圖片未更新。

controller('AppCtrl', function($scope,$window,$rootScope,$location,$http,$state,$cordovaCamera,$ionicLoading,$q,login_Service) 
{    
    $scope.user_Name=$rootScope.u_name;    
    $scope.uid=$rootScope.user_id; 
    $scope.pass=$rootScope.password; 
    $scope.user_Picture=$rootScope.pic; 
    $scope.whats=$rootScope.wh; 

    $scope.update_u=function(topic){  
     $scope.user_Picture=topic['picture']; 
     $scope.whats=topic['e_whats']; 
    }     
}); 

this is side-menu template 

<ion-side-menus> 

    <ion-side-menu-content> 
    <ion-nav-bar class="bar-light nav-title-slide-ios7"> 
     <ion-nav-back-button class="button-clear"><i class="icon ion-ios7-arrow-back"></i> Back</ion-nav-back-button> 
    </ion-nav-bar> 
    <ion-nav-view name="menuContent" animation="slide-left-right"></ion-nav-view> 
    </ion-side-menu-content> 
    <ion-side-menu side="left"> 

    <!-- Sidebar Content --> 
    <ion-content class="gem-sidebar dark"> 
     <!-- Profile Box - Extends ionic's .row --> 
     <div class="row gem-sidebar-profile-box"> 
     <!-- Profile Thumb --> 
     <div class="col col-25"> 
      <img src="img/gemionic/no-photo.jpg" ng-if="!user_Picture" class="gem-profile-image" alt=""> 
      <img src="http://www.cssolutionshub.com/php/images/user_img/{{user_Picture}}" ng-if="user_Picture" class="gem-profile-image"> 
     </div> 
     <!-- End Profile Thumb --> 

     <!-- Profile Name --> 
     <div class="col col-50"> 



      <h6> <a menu-close href="#" ng-click="edit_prof()">Edit Profile</a></h6> 
      <h5 ng-if="user_Name !== undefined">{{user_Name}}</h5> 
      <h4>{{whats}}</h4> 
     </div> 
     <!-- End Profile Name <a --> 

     <!-- Account Settings Icon --> 
     <div class="col col-25 gem-text-center"> 
      <i class="gem-profile-settings-icon ion-volume-high"></i> 
     </div> 
     <!-- End Account Settings Icon --> 

     </div> 
     <!-- End Profile Box --> 
     <!--<ion-list>   
     <ion-item class="item-ng-click" nav-clear menu-close ng-click="login()">Login</ion-item> 
     <ion-item nav-clear menu-close href="#/app/feed">Feed</ion-item> 
     <ion-item nav-clear menu-close href="#/app/start">Starter View</ion-item> 


     </ion-list> --> 
    </ion-content> 
    <!-- End sidemenu content --> 
    </ion-side-menu> 
</ion-side-menus>

，這是我的編輯模板，其中點擊更新功能

<!-- Title for header bar (refer to www/index.html) --> 
<ion-view title="Edit Profile"> 
    <!-- ======================

    <!-- ======================

    <!-- Standard Ionic List -->

什麼位代碼調用'$ scope.update_u（）'？ –

用於更新同一控制器內的用戶圖片 – sak

我看到它應該做什麼。你已經將它變成了這個'$ scope'的函數/方法，那麼你的代碼會調用它/觸發它來執行？這將幫助人們找出問題 –

嘗試以下操作：

$scope.update_u=function(topic){ 
    $scope.whats = topic.whats; 
    $scope.user_Picture=topic['picture']; 
}

感謝您的快速評論，我用它應用它did'nt工作，那麼如何使側面菜單圖片應該更新PLZ幫助 – sak

你能分享你的HTML或控制器的一部分你稱這個更新功能？ –

剛剛共享 – sak

你可以試試這個（中AppCtrl內）。 $ ionicView.beforeEnter函數中的代碼將在每次調用視圖時執行：

$scope.$on('$ionicView.beforeEnter', function() { 
     // Code you want executed every time view is opened 
     $scope.update_u=function(topic){  
      $scope.user_Picture=topic['picture']; 
      $scope.whats=topic['e_whats']; 
     } 
}

這也可能是由於控制器的高速緩存。您可以使用cache: false,行在route.js中停止它。 See this for a similar solution:
