Ng-Repeat:按唯一性过滤 [英] Ng-Repeat: Filter By Uniqueness

问题描述

虽然我安装了 ui-boostrap，但浏览器向我发送了一个错误 Error: [$injector:unpr] Unknown provider: uniqueFilterProvider <- uniqueFilter

json 对象

<代码>{"_id" : ObjectId("55b81956fde835be46f22294"),生活":真实，域":{隐藏":真实，名称":Eukarya"}，王国":{隐藏":真实，名称":动物界"}，"phylum" : { "hidden" : true, "name" : "Chordata" },"klass" : { "hidden" : true, "name" : "Mammalia" },"order" : { "hidden" : true, "name" : "carnivoria" },家庭":{隐藏":真实，名称":疱疹科"}，"genus" : { "hidden" : true, "name" : "galerelaa" },物种":{隐藏":真实，名称":猫鼬"}，照片":{隐藏":真实，网址":http://room909.com/wp-content/gallery/drawings-by-jared-flynn/snake-v-mongoose-web.jpg"}，__v":0}{"_id" : ObjectId("55b81956fde835be46f22295"),生活":真实，域":{隐藏":真实，名称":Eukarya"}，王国":{隐藏":真实，名称":动物界"}，"klass" : {"name": "Bivalvia", "hidden": true},"order" : { "hidden" : true, "name" : "Ostreoida" },"family" : {"name": "Ostreidae", "hidden": true},"genus" : { "hidden" : true, "name" : "" },物种":{隐藏":真实，名称":"}，照片":{隐藏":真实，网址":http://a-z-animals.com/media/animals/images/470x370/oyster5.jpg"}，__v":0}

html

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

</节>

我还尝试了对唯一值的变化，例如 domain.name 和 domain，但它们都带来了相同的错误.

解决方案

我找到了答案.我们所要做的就是简单地安装美妙的、天才的、不可替代的 a8m angular-filter 库与 bower/npm，添加到我的依赖项数组 (@Joy)，并使用语法 ng-repeat="animal in animal | unique: 'domain.name'" 一切正常.

Though I have ui-boostrap installed, the browser shoots me an error Error: [$injector:unpr] Unknown provider: uniqueFilterProvider <- uniqueFilter

html

<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>

I've also tried variations on the unique's value like domain.name and domain, but they all bring the same error.

解决方案

I found an answer. All we have to do is, instead, simply installed the wonderful, genius, un-replaceable a8m angular-filter library with bower/npm, added to my array of dependencies (@Joy), and used the syntax ng-repeat="animal in animals | unique: 'domain.name'" and everything works fine.
