NG-重复残疾选项中进行选择 [英] ng-repeat select with disabled options

问题描述

我有阵

vm.helpersIterator = [ ] //store new <select>-s

和对象这样

vm.helpersObj = {
    2014: {name: 'test', selected: true},  
    1290: {name: 'test1', selected: false},
}

HTML

<select name="helper" class="form-control"
   ng-repeat="helper in vm.helpersIterator track by $index">
     <option value="">- Select helper -</option>
     <option ng-repeat="(uid, helper) in vm.helpersObj"
             ng-value="uid"
             ng-selected="helper.selected">
             {{helper.name}}
      </option>
</select>

我就可以把许多＆LT;选择＆GT; -s在vm.helpersIterator阵列。
但我需要禁用它已经选定的选项。

I'll can push many <select>-s in vm.helpersIterator array. But I need to disable options which already been selected.

我也用 NG-变化用于设置selectedOption为选
