Working with Angular's forEach method and handling null values

I'm encountering an issue where the array of selected devices is not getting the values when attempting to add multiple devices to a group. Can someone identify the problem or suggest an alternative method? I referred to http://www.dotnetawesome.com/2015/12/multiselect-dropdown-with-checkbox-in-angularjs.html as a reference for the service I developed.

Below is the Angular code snippet:


// Angular module and controller initialization
var MyApp = angular.module('MyApp', ['ui.bootstrap', 'angularjs-dropdown-multiselect']);
MyApp.controller('GroupsController', ['GroupsService', '$scope', '$log', '$uibModal',
function (GroupsService, $scope, $log, $uibModal) {
    // Controller logic goes here...
}]

Here's the view code snippet:


// HTML view code
@model List<NetworkCafe.Models.DeviceGroup>

<style>
// CSS styling goes here...
</style>
<link rel="stylesheet" href="../Content/font-awesome.min.css">
<div class="container" style="width:90%" ng-app="MyApp" ng-controller="GroupsController">
// HTML structure continues...
</div>

@section scripts{
// JavaScript scripts imports go here...
}

Answer №1

Your forEach loop is not quite right.

angular.forEach($scope.SelectedDevices = function (value) {
            $scope.deviceIDs.push({ dname: value.HostName, dguid: groupguid } );
        });

The correct syntax should be :

angular.forEach($scope.SelectedDevices, function (value) {
            $scope.deviceIDs.push({ dname: value.HostName, dguid: value.groupguid } );
        });
