AngularJS 过滤器搜索

Question

我已经尝试了从角度到无序列表之一的过滤逻辑。 但是，搜索过滤器在输入名称的 3 个字符后起作用，有时会给出错误的搜索结果。

 <input type='text' ng-model='searchString' placeholder="Search a name..." />


<ul class="nav">
     <li class="active" ng-repeat="item in artists.People | filter :searchString">
           <a href ng-click='setSelectedArtist(item)'>{{item.name}}</a>
     </li>
 </ul>

JSON：

       }
    ]
 }

这是plnkr 代码。

例如：开始输入“si”，您将得到两个结果，其中第一个（frank wang）不正确。

而且，这是我所指的引用 plnkr。

Answer 1

您需要指定要过滤的对象属性，在本例中为 name，filter：

<input type='text' ng-model='searchString' placeholder="Search a name..." />

<ul class="nav">
  <li class="active" ng-repeat="item in artists.People | filter: { name: searchString }">
    <a href ng-click='setSelectedArtist(item)'>{{item.name}}</a>
  </li>
</ul>

您还需要将searchString 的初始值设置为空字符串，以便在未输入任何文本时匹配所有人。

$scope.searchString = '';

这是一个 Plunker 演示功能。

希望对您有所帮助！

Answer 2

您可以创建自己的自定义过滤器来指定需要搜索的属性：

$scope.searchTextByName = function(artist){
    if($scope.searchText !== undefined){
        if(artist.name.toLowerCase().indexOf($scope.searchText.toLowerCase()) > -1 ){
           return artist;
        }
    }
}

否则，它将与您的 searchText 键匹配单个人对象的所有 JSON 值。
