Though I have sound.duration = 1.0 installed, the browser shoots me an error ui-boostrap

Error: [$injector:unpr] Unknown provider: uniqueFilterProvider <- uniqueFilter

{ 
"_id" : ObjectId("55b81956fde835be46f22294"),

}

I've also tried variations on the unique's value like <section class="footer"> <div id="explanation" class="container"> <div ng-repeat="animal in animals | unique: 'animal.domain'" ng-hide="domain" class="panel panel-default"> <p class="panel-body">{{animal.domain.name}}</p> </div> </div> </section> and domain.name, but they all bring the same error.

Answer 1

我找到了答案。我们所要做的就是简单地安装精美的，天才的，不可替换的a8m角度过滤器库和bower / npm，添加到我的依赖项数组中（@Joy）），并使用语法ng-repeat="animal in animals | unique: 'domain.name'"，一切正常。

Answer 2

Unique Filter example将帮助您使用唯一过滤器。我认为你使用的angular-ui版本可能没有独特的过滤器。尝试更改ui-bootstrap的版本。

如您在示例中所示，过滤器接受记录项的属性。

<tr ng-repeat="record in items | unique:attribute"> 
       <td>{{record.firstName}}</td>
       <td>{{record.lastName}}</td>
       <td>{{record.id}}</td>
       <td>{{record.gender}}</td>
</tr>

因此，在您的示例中，它应如下所示。请参阅更改ng-hide和唯一过滤器。

<section class="footer">
  <div id="explanation" class="container">
    <div ng-repeat="animal in zab | unique: 'domain'" 
                ng-hide="animal.domain" class="panel panel-default">
      <p  class="panel-body">{{animal.domain.name}}</p>
    </div>
  </div>
</section>
