Angular Bootstrap DropDown按钮不加载数据

Question

我试图将数据加载到DropDown控件中，但它没有加载请找到下面的代码

Java脚本文件中的代码

 var employeeEntries = Employee.query(function () {    
            $scope.Employeedata = JSON.stringify(employeeEntries);            
            $scope.Employeedata = employeeEntries;
            console.log($scope.Employeedata)
            console.log($scope.Employeedata[0].employee_firstname)
        });

  $scope.setAction = function (action) {
            $scope.selectedAction = action;
        };

我的HTML文件中的代码

   <div class="btn-group" dropdown>
    <button type="button" class="btn btn-default" ng-click="submit()">{{Employeedata.employee_firstname}}</button>
    <button type="button" class="btn btn-default dropdown-toggle">
      <span class="caret"></span>
      <span class="sr-only">Split button!</span>
    </button>
    <ul class="dropdown-menu" role="menu">
      <li ng-repeat="emp in Employeedata  track by $index">
        <a href="#" ng-click="setAction(action)">{{emp.employee_firstname}}    </a>
      </li>
    </ul>
  </div>
