Question

I have a C# .NET web app and would like to implement an UNDO feature in each of the Views. The below url is what I am doing to trap the “CTL->Z” key combination. MVC3 jQuery keyup event Any ideas how to restore the values of each of the fields on the View after a “CTL->Z” combo is used?

Answer 1

Store the previous values in in a custom attribute.

$(control).attr("data-undo", $(control).val());

If you need it, just write it back to the input.

$(control).val($(control).attr("data-undo"));
