'ng-repeat'如何获得`unique'值

本文介绍了'ng-repeat'如何获得`unique'值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

使用数组，我试图过滤并在列表中显示unique信息.为此，我使用angular inbuild filter方法.

Using an array, I am trying to filter and show the unique information in the list. For that I use the angular inbuild filter method.

但是我遇到了错误.

这是我的尝试(我正在按SubProjectName进行过滤)

Here is my try (I am filtering by SubProjectName)

<ul>
    <li ng-repeat="project in projectNames | unique: 'SubProjectName' ">
        {project.SubProjectName}}
    </li>
</ul>

AngularJS默认不包含unique过滤器.您可以使用 angular-filter 中的一个.只需包含JavaScript

AngularJS doesn't include a unique filter by default. You can use the one from angular-filter. Just include the JavaScript

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-filter/0.5.8/angular-filter.min.js"></script>

并在您的应用中添加依赖项:

and include the dependeny in your app:

var app = angular.module('myApp', ['angular.filter']);

您的代码应立即生效！我编辑了您的 Plunker ，这样就可以了.

Your code should work right away! I edited your Plunker so it works.
