How to get value from multiple select option in controller

Question

I want get all selected from me result,for using in my controller.

<div class="form-group" ng-repeat="att in arr track by $index"  ng-hide="check">
   <div class="col-md-3">
        <label for="phone">{{att.name}}</label>
   </div>
   <div class="col-md-9">
        <select class="form-control" ng-model="user.charactValue" multiple="true">
            <option ng-repeat="itemss in att.value track by $index" value="{{itemss}}" >{{itemss}}</option>
        </select>
        <div class="text-center"><a  data-toggle="modal" data-target="#addNewCharacteristic" ng-click="getObj(att)">Добави</a></div>
   </div>
</div>
<input type="submit" ng-click="companyBusinessAsset">

$scope.companyBusinessAsset = function() {
    console.log ($scope.charactValue);
    // this return Undefined
};

Down code is using, but each time they enter into if.

$scope.charactValue = [];

$scope.$watch ('selected', function(nowSelected) {
    $scope.selectedValues = [];
    console.log(nowSelected)
    // this return Undefined
    console.log('dddd')
    if (!nowSelected) {
        console.log("IFFFFFF");
        return;
    }
    angular.forEach ($scope.charactValue, function(val) {
        console.log(val);
        $scope.charactValue.push (val.id.toString());
    });
});

尝试将ng-multiple="true"到select 。

Answer 2

I did this in one of my projects as below, hope this helps:

 <select multiple="multiple" name="selectedRoleId" ng-model="user.selectedRole" class="form-control">
      <option ng:repeat="role in roleList" value="{{role.Name}}">{{role.Name}}</option>
 </select>

then in the submit function in the controller:

//declare $scope.user to avoid undefined/notfound error
$scope.user = {}; //above the function
//and inside the function
$scope.submitForm=function() {
    var reguser = new models.register($scope.user);
};

you will get the multiple selected values in $scope.user 's selectedRole property
