AngularJS过滤器搜索

Question

我已经尝试了从角度到无序列表的过滤逻辑。但是，在键入3个字符的名称后，搜索过滤器就会工作，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"，你会得到两个结果，其中第一个(王(不正确。

这就是我所指的参考plnkr。

Answer 1

您需要指定哪个对象属性，在本例中是name，以便filter进行过滤：

<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，以便在没有输入文本的情况下与所有人匹配。

$scope.searchString = '';

这是一个演示功能的Plunker。

希望这能有所帮助！

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，它将使用您的searchText键匹配单个人员对象的所有JSON值。
