  </head>
  <body ng-controller="MainCtrl">
    <p>Hello {{name}}!</p>
    <select chosen class="red" ng-model="bar">
      <option>Hi</option>
      <option>This is fun</option>
      <option>I like Chosen so much</option>
      <option>I also like bunny rabbits</option>
      <option value=""></option>
    </select>
  </body>
</html>

JS 

var app = angular.module('plunker', ['localytics.directives']);
app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';
});

您可以看到，我尝试将类red添加到由angular-chosen创建的div中，并与其他类chosen-container chosen-container-single一起添加。我不想手动更改这些类。

确保添加额外类的正确方法是什么?

谢谢

看起来chosen.jquery.js的第153行有一个默认为false的inherit_select_classes选项。

chosen.js中指令的第39行查看options的chosen属性:

options = scope.$eval(attr.chosen) || {};

让你的select标记:

<select chosen="{inherit_select_classes:true}" class="red" ng-model="bar">

导致生成以下内容:

<div class="chosen-container chosen-container-single red ng-pristine ng-valid localytics-chosen" >

(省略与此问题无关的额外属性)
