AngularJS bind class attribute to model


AngularJS bind class attribute to model

I hope this helps . Since selectedRoles is an array of role ids you could just use array.indexOf to find if it in the selected list:-
code :
<div ng-class="{ big: selectedRoles.indexOf(role.id)+1 }">
$scope.hasRole = function(id){
  return $scope.selectedRoles.indexOf(id) > -1;
}
<div ng-class="{ big: hasRole(role.id) }">

Does that help Here's a fork of your jsFiddle with three variations so that you can see different methods.
I used the simpler syntax for binding. I think you'll find your code easier to read with the {{braces}}.
code :
John is {{friends[0].name}} and has id {{friends[0].id}}
Joy is {{friends[joy].name}} and has id {{friends[joy].id}}

$scope.joy = 1;    // in the javascript
Peter is {{getFriend(9).name}} and has id {{getFriend(9).id}}

$scope.getFriend = function(fid) {

    angular.forEach($scope.friends, function(friend, key) {
        if (friend.id == fid) {
            found = friend;
        }
    });
    return found;
};

With these it helps If you want to dynamically add Angular directives like ng-model, ng-bind etc. you must create your own directive and use $compile.
You can use angular ng-show or ng-switch to switch showing DOM elements without bindings and elements with ng-model and other attributes that you need.

Any of those help The reason is that = is used to bind to variable in parent scope contained within the attribute value
Your color values are not scope variables in the parent scope(controller), they are only strings in your use case. There is no $scope.green or $scope.blue in controller to bind to.
code :
function mainController($scope) {
    $scope.message = 'alsjkf';
    $scope.blue ='#0B0EFF';
}

This might help you After page load, the model and radio button display correctly. , Ah, simply change your repeater to
code :
ng-repeat="item in list track by $index"

I think the issue was by ths following , There are ways of doing this with nicer UI (this might get you started: Passing the collection of selected values from a Select2-Multi DropDownList to a Controller)
But to answer your exact question: Use a string property in your ViewModel to "wrap" the List property.
code :
public class MyViewModel
{
    public List<string> MyList { get; set; }
    public string MyListAsString
    {
        get
        {
            return string.Join(",", MyList);
        }
        set
        {
            MyList = value.Split(new char[] { ',' }).Select(x => x.Trim()).ToList();
        }
    }
}
@Html.TextAreaFor(model => model.MyListAsString,
                  htmlAttributes: new { @class = "control-label col-md-2" })
