Javascript 动态下拉菜单角度和引导

尝试为按钮创建动态下拉菜单。从服务器将菜单预加载为json，这部分工作正常，但出于某些原因，bootstrap不会显示菜单项，除了数组中的最后一项

<div class="btn-group">
    <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown"> 
        <span class="glyphicon glyphicon-camera"></span> Select images to view <b class="caret"></b>
    </button>
    <ul ng-repeat="tag in tags" class="dropdown-menu">
        <li><a href="#" ng-click="view.setTag(tag)">{{tag}}</a></li>
    </ul>
</div>

（不过这很好）

经过一些实验后发现了问题。将ng重复移动到li元素，如下所示

    <div class="btn-group">
        <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown"> 
            <span class="glyphicon glyphicon-camera"></span> Select images to view <b class="caret"></b>
        </button>
        <ulclass="dropdown-menu">
            <li  ng-repeat="tag in tags"><a href="#" ng-click="view.setTag(tag)">{{tag}}</a></li>
                 ^^^^^^^^^^^^^^^^^^^^^^^
        </ul>
    </div>

选择要查看的图像

^^^^^^^^^^^^^^^^^^^^^^^

    this.loadTags = function () {
        $http.get('http://localhost:5566/api/tags').
        success(function (data, status, headers, config) {
            $scope.tags = data.tags;
        }).
        error();
    }

    <div class="btn-group">
        <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown"> 
            <span class="glyphicon glyphicon-camera"></span> Select images to view <b class="caret"></b>
        </button>
        <ulclass="dropdown-menu">
            <li  ng-repeat="tag in tags"><a href="#" ng-click="view.setTag(tag)">{{tag}}</a></li>
                 ^^^^^^^^^^^^^^^^^^^^^^^
        </ul>
    </div>
