html - 如何使用 AngularJS orderBy

Question

我认为我的语法不正确？我可以在 Angular 中执行此操作吗？前两个过滤器有效但不是 order bys

<div class ="col-md-8 pull-left">
      <span ng-click="myFilter = {green: true}">Clean</span>  |
      <span ng-click="myFilter = {green: false}">Dirty</span> |
      <span ng-click="myFilter = orderBy: 'governance' : true">Goverance</span> |
      <span ng-click="myFilter = orderBy: 'environmental' : true ">Environmental</span> |
      <span ng-click="myFilter = orderBy: 'community' :true">Community</span> |
      <span ng-click="myFilter = null">All</span>
</div>

<div class="list-group-item col-md-8 pull-left" ng-repeat="site in list.links | filter:myFilter">
{{site.governance}}
{{site.environmental}}
{{site.community}}
</div>

一个示例对象是

{
      name: 'Facebook',
      url: 'www.facebook.com',
      green: false,
      governance: 45,
      environment: 69,
      community: 72,
      rank: 6
    }

Answer 1

你的语法有误，你不能那样设置，filter 和 orderBy 是两个不同的过滤器，采用 2 个不同的表达式。而是在点击时设置一个顺序变量。

<div class ="col-md-8 pull-left">
     ...
      <span ng-click=" order='governance' ">Goverance</span> |
      <span ng-click=" order='environmental' ">Environmental</span> |
      <span ng-click=" order='community' ">Community</span> |
     ...
</div>

并使用变量:-

ng-repeat="site in list.links | filter:myFilter |orderBy:order"

可能还有一种:-

 <span ng-click=" order='governance'; sort=!sort ">Goverance</span>
....
<div .. ng-repeat="site in list.links | filter:myFilter |orderBy:order:sort"
