AngularJS ng-repeat using $index in a filter

Question

I'm using ng-repeat and trying to use the $index in a filter like this

<div data-ng-repeat="i in [1,2,3,4,5,6,7,8,9]">            
  <div ng-repeat="student in students | filter:{Surname:'Smith', Group: {{$index}}">
    <span ng-click="updateStudent(student.StudentID)">{{student.FullName}}</span>
  </div>
</div>

I'm getting a syntax error in the Chrome dev tools console. Is it possible to use $index like this?

I have also tried Group: $index without the braces

Answer 1

你不需要双括号，因为你正在使用ng-repeat ，但你也错过了最后的}

ng-repeat="student in students | filter:{Surname:'Smith', Group: $index}"
