javascript - 仅在<选择多个>中选中

Question

我试图仅获取名称列表中已检查的名称。这是我的代码模型:

<select ng-model="selectTopic" ng-change="changedTopic(selectTopic)" ng-options="option as option for option in topics">>
    <option value="" disabled>Select a Subject</option>
</select>

<select ng-model="selectDept" ng-change="changedDepartment(selectDept)" ng-options="option as option for option in department">
    <option value="" disabled>Select a Department</option>
</select> 
				  
<select ng-model="selectUser" ng-options="option as option for option in users" multiple="multiple">
	<option value="" disabled>Select a User</option>  
</select>

我想获取选定的主题、部门和用户。我目前正在使用: console.log($scope.topics + $scope.departments + $scope.users) 但它返回所有内容。我只想退回所选项目。

谁能帮帮我吗？

您必须打印 ng-models ，而不是数组:

console.log($scope.selectTopic);
console.log($scope.selectDept);
console.log($scope.selectUser);

希望有帮助 =)
