角度选择中的选定选项

Question

我选择了ng-repeat:

<select class="span5 ui-select2 id="goal_{{goal.id}}" multiple="multiple">
  <option ng-repeat="counterGoal in counterGoals" value="{{counterGoal.id}}">{{counterGoal.name}}</option>
</select>

在goal模型中我有counter_goal_ids像数组[1,2,3,4,5,6].如何选择包含的选项goal.counter_goal_ids？

Answer 1

请尝试以下方法:

您可以使用ng-selected属性和模型中的自定义函数来选择选项

ng-selected="isInGoalIds({{counterGoal.id}})"

在您的模型中,添加一个函数

$scope.isInGoalIds = function(id){
    angular.forEach($scope.counter_goal_ids, function(value, index){
      if(id == value){
        return true;
      }
    });
    return false;
}
