<section class="popup-bg" ng-if="IsActive">
 <div class="popup-box phone-detail">
  <div class="popup-  popup-detail- ">通讯录
   <i class="iconfont popup-close-font rights " ng-click="HideMail()"></i>

     <input type="checkbox" ng-model="active" class="checkboxs" value="User.Name"
       ng-click="itemSelected($event,User.Id,active)">
    </div>
   </div>
  </div>
 </div>
</section>

$scope.itemIds = [];
$scope.active = false;
$scope.itemSelected = function ($event, pid, active) {
 var checkbox = $event.target;
 if (checkbox.checked) {
  $scope.itemIds.push(pid);
 } else {
  $scope.itemIds = Tools.arrRemove($scope.itemIds, pid);
 }
 console.log(active);
 console.log($scope.itemIds);
};
