How to use filter with in ng-repeat using Angular js?

问题

All I want to filter some values with in ng-repeat, I have tried but haven't got a solution...

My Plunker.
I am looking for three kinds of solution,

(i) In my plunker first, i am looking to filter ng-module="request_role" value of parent in the list. so I had tried like | filter: request_role.[parent'].

(ii) In my plunker second list, i am looking to filter ng-module="request_role" value of Change Agent. so I had tried like | filter: request_role.['Change Agentent'].

(i) In my plunker third list, i am looking to filter ng-module="request_role" value of parent,Change Agent. so I had tried like | filter: request_role.['parent,Change Agent'].

I think I have done a mistake in filter, so please check and update my plunker as well to know exact solution, thanks...

My Html:-

<p style="background: black;color:white">1.Filter request_role  value of `parent` data's in below list</p>
        <div  ng-repeat="question in users | filter: request_role.['parent']">
            <small>
              <table border="0">
                <tbody>
                  <th>{{question.displayName}}</th>
                <th style="background: yellow;">,{{question.roles[0]}}</th>
                <th style="background: light;">,{{question.request_role[0]}}</th>

                </tbody>
                      </table>


              </small>
        </div>

        <p style="background: black;color:white">2. Filter request_role  value of `Change Agent ` data's in below list</p>
        <div  ng-repeat="question in users | filter: request_role.['Change Agent']">
            <small>
              <table border="0">
                <tbody>
                  <th>{{question.displayName}}</th>
                <th style="background: yellow;">,{{question.roles[0]}}</th>
                <th style="background: light;">,{{question.request_role[0]}}</th>

                </tbody>
                      </table>


              </small>
        </div>

         <p style="background: black;color:white">3.Filter request_role  Both value of ["parent","Change Agent"] data's in below list</p>
        <div  ng-repeat="question in users | filter: request_role.['parent,Change Agent']">
            <small>
              <table border="0">
                <tbody>
                  <th>{{question.displayName}}</th>
                <th style="background: yellow;">,{{question.roles[0]}}</th>
                <th style="background: light;">,{{question.request_role[0]}}</th>

                </tbody>
                      </table>


              </small>
        </div>

My filter:-

  1. | filter: request_role.['parent']

    2.  | filter: request_role.['Change Agent']

3. | filter: request_role.['parent,Change Agent']

You can solve this using a custom filter or directly by applying a filter on ng-repeat as shown below

<div ng-repeat="question in users | filter: {'request_role':'parent'}">
<div ng-repeat="question in users | filter: {'request_role':'Change Agent'}">
<div ng-repeat="question in users | filter: {'request_role':'Change Agent','request_role':'parent'}">
