Knockout MVC also supports simple computed properties. These properties have a JavaScript representation and can be calculated on the client without additional requests to the server. For example, let's define a computed property DisplayText for our BookModel. This property will be calculated on the basis of Author and Title.
The Model will be as follows:
public class BookModel
{
public string Title { get; set; }
public string Author { get; set; }
[Computed]
[ScriptIgnore]
[JsonIgnore]
public string DisplayText
{
get { return Author + ": " + Title; }
}
}
public class LibraryModel
{
public List<BookModel> Books { get; set; }
}The Controller will be as follows:
public class LibraryController : KnockoutController
{
public ActionResult Index()
{
var model = new LibraryModel
{
Books = new List<BookModel>
{
new BookModel { Title = "Oliver Twist", Author = "Charles Dickens" },
new BookModel { Title...
