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

问题描述

我有以下下拉这是工作的罚款

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>

这让我在下面的下拉选项

It gives me following options in the dropdown

          101
          101
          119
          120
          121
          121

尽管应该只显示为...

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

       101
       119
       120
       121

帐户由贾森阵列帐户其中有
act_id（主键）
ID
FNAME
LNAME
位置

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

你能告诉我如何解决对ID唯一的过滤器，以便只显示唯一值感谢

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

推荐答案

AngularUI 有什么你需要时，'unique'过滤器。

AngularUI has exactly what you need, the ´unique´ filter.

例如：

ng-options="color in colors | unique:'name'"
