How do I switch a result value based on a condition?

[Helene Francke]

Hi!

I'm trying to change a resource collected through an ajax call based on the status for that particular resource. The data I receive is an array of JSON-objects and in each object there is a property populated with a link to an image. Although the link is always there, the image it links to isn't. So what I would like to do in my success call is something like this:

function viewModel () {

    

    this.employeeList = ko.observableArray([]);

    //ajax call......

    success: function (data) {

                    

                    var mappedEmpl = $.map(data, function (item) {

                        return {

                            Name: item.Name,

                            Position: item.Position,

                            Department: item.Department,

                            ShortNumber: item.ShortNumber,

                            Mail: item.MailAddress,

                            RoomNo: item.RoomNo,

                            EmployeeNo: item.EmployeeNo,

                            image: item.ImageUrl

                           if (image.status === 404) {

                                    //set src-attribute to a default image

                          }

                        }

                    });

                    this.employeeList(mappedEmpl);

                },

}

ko.applyBindings(new EmployeeDataModel());

Is there an easy way of doing this, or am I going to have to split them up into seperate ajax calls? I already tried to use onerror, but that apparently targeted ALL the images regardless if it existed or not.

Thanks!
