Javascript 角度射击，重复

我有下面的代码，显示发布到Firebase的内容

var app = angular.module("myapp", ["firebase"]);
function MyController($scope, $firebase) {
    var ref = new Firebase(".....");
    $scope.messages = $firebase(ref.endAt().limit(100));
}

<div ng-app="myapp">
        <div id="links" ng-controller="MyController">                
            <a ng-repeat="msg in messages" href="{{msg.highResUrl}}" data-gallery>
                <img src="{{msg.imgUrl}}" style="width: 140px"/>
                 <!--This repeat isn't working-->
                 <ul>
                      <li ng-repeat="tag in msg.tags">{{tag}}</li>                     
                 </ul>

            </a>
        </div>
    </div>

除内部ng repeat on标记外，所有其他数据都有效。有什么想法吗

谢谢

看看这个。它似乎适用于某些夹具数据

测试数据：

$scope.messages = [{
                   "highResUrl" : "",
                   "Source" : "",
                   "title" : "Img",
                   "tags" : [ "Tag1", "Tag2", "Tag3", "Tag4" ],
                   "imgUrl" : ""
                  },
                  {
                   "highResUrl" : "",
                   "Source" : "",
                   "title" : "Img",
                   "tags" : [ "Tag1", "Tag2", "Tag3", "Tag4" ],
                   "imgUrl" : "http://devgirl.org/wp-content/uploads/2013/03/angular-logo.jpeg"
                  },
                  {
                   "highResUrl" : "",
                   "Source" : "",
                   "title" : "Img",
                   "tags" : [ "Tag1", "Tag2", "Tag3", "Tag4" ],
                   "imgUrl" : "http://devgirl.org/wp-content/uploads/2013/03/angular-logo.jpeg"
                  },
                  {
                   "highResUrl" : "",
                   "Source" : "",
                   "title" : "Img",
                   "tags" : [ "Tag1", "Tag2", "Tag3", "Tag4" ],
                   "imgUrl" : "http://devgirl.org/wp-content/uploads/2013/03/angular-logo.jpeg"
                  }];

消息是数组吗？你能试试$index的消息跟踪中的

消息吗。。。什么不起作用？内部ng重复做什么？有什么错误吗？只要将提供的数据输入Firebase，我就可以了-
$scope.messages = [{
                   "highResUrl" : "",
                   "Source" : "",
                   "title" : "Img",
                   "tags" : [ "Tag1", "Tag2", "Tag3", "Tag4" ],
                   "imgUrl" : ""
                  },
                  {
                   "highResUrl" : "",
                   "Source" : "",
                   "title" : "Img",
                   "tags" : [ "Tag1", "Tag2", "Tag3", "Tag4" ],
                   "imgUrl" : "http://devgirl.org/wp-content/uploads/2013/03/angular-logo.jpeg"
                  },
                  {
                   "highResUrl" : "",
                   "Source" : "",
                   "title" : "Img",
                   "tags" : [ "Tag1", "Tag2", "Tag3", "Tag4" ],
                   "imgUrl" : "http://devgirl.org/wp-content/uploads/2013/03/angular-logo.jpeg"
                  },
                  {
                   "highResUrl" : "",
                   "Source" : "",
                   "title" : "Img",
                   "tags" : [ "Tag1", "Tag2", "Tag3", "Tag4" ],
                   "imgUrl" : "http://devgirl.org/wp-content/uploads/2013/03/angular-logo.jpeg"
                  }];
