javascript - angularjs ng-repeat 循环不同的样式

Question

我想实现 跳转按钮是红色，删除按钮是蓝色，添加是白色，但是目前这样循环的话，全是“btn-warning”这个样式，也就是红色！

angular.module('demoAPP').controller('demoCtrl', function($scope) {
  var demoData = [
    {
      "Name" : "操作",
      "action" : "跳转"
    },
    {
      "Name" : "操作",
      "action" : "删除"
    }
    {
      "Name" : "操作",
      "action" : "添加"
    }
  ]
  $scope.demo = demoData;
    });

<table>
    <tr ng-repeat="item  in demo">
      <td>{{item.Name}}</td>
      <td><button type="button" class="btn btn-warning">{{item.action}}</button></td>
    </tr>  
</table>

Answer 1

ng-class should do the trick.

Answer 2

ng-class="{'Style':item.action=='Jump'}"
ng-class="{'Style':item.action=='Add'}"
ng-class="{ 'Style':item.action=='Modify'}"
Execute style when ng-class is true

Answer 3

Multiple styles in ng-class are separated by commas, and write all three judgments in the repetition.
