angularjs - Angular 选择了具有默认值的多个

Question

HTML：

       <select chosen multiple class="form-control" ng-model="model.Skills"
          ng-options="skills.name.skillName for skills in skills" 
data-placeholder="Select Skills" >
          <option value=""></option>
        </select>

$scope.skills = [
  {
    "skillName": "C",
    "idx": "0"
  },
  {
    "skillName": "C++",
    "idx": "1"
  },
  {
    "skillName": "Java",
    "idx": "2"
  }
]

idx 是技能的索引。我选择的角度进行多选。我想设置我的默认值，Java and C所以我设置如下

$scope.model = {};

$scope.model.Skills = [2,1];

$scope.selected = 2;

但它不工作。https://plnkr.co/edit/cQEB5T?p=preview我使用了以下示例。

根据此代码段更改您的代码...

<select
   chosen multiple
   ng-model="model.Skills"
   ng-options="s.idx as s.skillName for s in skills ">
   <option value=""></option>
</select>
