是新的火力點和離子和我創建聊天應用程序，將 讓我的應用程序用戶能夠直接與聊天另一個，我有 成功地能夠註冊用戶;獲取用戶，也已經 能消息中的每個用戶，但我的地方混亂的是我應該如何去 顯示消息

這裏是我的火力地堡結構

Firebase Structure

這裏是我的看法代碼

<ion-view view-title="Home Page"> 

<ion-content delegate-handle="show-page" > 

    <!-- Loading Indicator --> 
    <div class="loading" 
     ng-if="data.loading" > 
     <ion-spinner icon="ripple" ></ion-spinner > 
     <p >Loading messages...</p > 
    </div > 

    <!-- Empty room message --> 
    <div class="loading" 
     ng-show="!data.loading && data.message.length == 0" > 
     <p >This room is empty, be the first to post!</p > 
    </div > 

    <!-- Discussion list --> 
    <div class="chat-messages"> 
     <ul> 
      <li ng-repeat="data in chatMessages"> 
       {{data.message}} 
      </li> 
     </ul> 
    </div> 

</ion-content> 

<ion-footer-bar keyboard-attach 
       class="bar-assertive item-input-inset" > 
    <label class="item-input-wrapper" > 
     <input type="text" 
       placeholder="Type your message" 
       ng-enter="sendMessage()" 
       ng-model="data.message" /> 
    </label > 
    <button class="button button-clear" 
      ng-click="sendMessage()" > 
     Send 
    </button > 
</ion-footer-bar > 

，這裏是我的控制器

app.controller('chatCtrl', function ($scope, $state, $stateParams, $localStorage) { 
    $scope.data = { 
      messages: [], 
      message: '', 
      loading: true, 
      showInfo: false 
    }; 
    var to      = $stateParams.UserName; 
    $localStorage.from   = $stateParams.MyName; 



    var roomName = 'chat_'+(to<$localStorage.from ? to+'_'+$localStorage.from : $localStorage.from+'_'+to); 

    console.log(to+', '+$localStorage.from+' => '+ roomName); 


    var messagesRef = new Firebase("https://bigzill.firebaseio.com/chatMessages/"+roomName); 
    $scope.loadMessages = function() { 
     $scope.data.messages =$firebaseArray(messagesRef); 
     $scope.data.messages.$loaded().then(function(data){ 
      console.log("Angular fire $loaded"); 
      $scope.data.loading =false; 
      $ionicScrollDelegate.$getByHandle('show-page').scrollBottom(true); 
     }); 
    }; 
    $scope.sendMessage = function(){ 
      var to    = $stateParams.UserName; 
      $localStorage.from = $stateParams.MyName; 
      var from    = $stateParams.MyName; 
      var dataToDb   = {from: from, to: to, message: $scope.data.message,timestamp: new Date().getTime()}; 
      var roomName = 'chat_'+(to<from ? to+'_'+from : from+'_'+to); 
      var InsertChatRef = new Firebase('https://bigzill.firebaseio.com'); 
      var insertObj =InsertChatRef.child('chatMessages').child(roomName); 
      insertObj.push(dataToDb); 

      $scope.data.message = ''; 

    }; 
});

哇...編碼涉及看到一個尖銳敏感的眼睛。我能夠 找出問題。

該消息正在顯示。

，我所做的就是我的loadMessage（）函數有 $ scope.data.messages在我看來，我是NG-重複從一個非常 錯誤$範圍，所以我將其更改爲NG-重複=「數據data.messages」和 它的工作
