在 Angularjs 中显示独特的下拉选项 [英] Showing unique dropdown options in Angularjs

问题描述

我有一个工作正常的以下下拉菜单

I have a following drop down which is working fine

                     <select class="form-control" ng-model="cc.id">
                       <option value="">Chose Id</option>
                       <option ng-repeat="account in accounts |unique:'id'" value="{{account.id}}">{{name.id}}</option>
                       </select>

它在下拉列表中为我提供了以下选项

It gives me following options in the dropdown

          101
          101
          119
          120
          121
          121

虽然它应该只在选项中显示唯一 id 为...

While it should be only showing the unique id in options as...

       101
       119
       120
       121

Accounts 由 Account 的 jason 数组组成，它具有act_id(主键)ID名称名称位置

Accounts consists of jason array of Account which has act_id (primary key) id fname lname location

你能告诉我如何修复 id 上的唯一过滤器，以便它只显示唯一值谢谢

Can you please tell me how to fix the unique filter on id so that it displays only unique values Thanks
