ASP.NET MVC Html.textbox - How to validate numbers only?

Question

With the HTML helper, how would you enforce number only without submitting? I know it was done with regular expression if you had a textbox in classic ASP.NET

<%=Html.TextBox("txtYearOfWork",String.Empty, new { maxlength = 4, size="5", autocomplete = "off" }) %>

Answer 1

If the data type on the model is numeric (int, etc) you can just use an attribute, and turn on client validation. More details here.

Answer 2

Another option would be to use the jquery Validation Plugin.

This would allow you to just add the class "required digits" and it would do the validation magic for you.
