列表中选中的AngularJS复选框

Question

I have a list called positions that has N positions in them. 我有一个名为positions的清单，其中有N个职位。 I also have a user user that has an attribute user.positions that has some of the positions assigned to. 我也有一个用户user ，该用户具有一个属性user.positions ，该属性已分配了一些位置。

I want to show a form with all the possible positions, and the positions that the user already has to be checked. 我想显示一个表格，其中包含所有可能的位置，以及必须检查用户的位置。

Is this something I can do inside the HTML, or do I need to loop through both in my logic and create a new variable? 这是我可以在HTML内部执行的操作，还是需要在我的逻辑中循环遍历并创建一个新变量？

Answer 1

<label ng-repeat="position in positions">
  <input type="checkbox" ng-checked="user.positions.indexOf(position) != -1" /> {{position}}
</label>
