问题 In my razor view that using knockout and supposedly knockout validation I add the following line (to actually start using ko validation): <script src="@Url.Content("~/Scripts/knockout.validation.debug.js")" type="text/javascript"></script> When I run this view in Chrome validation is working perfectly.

问题 What is the best way to get the selected item value from a dropdown list box when the user does one of the following; hits the tab key on the item, presses the enter key or mouse clicks the item.
