Clientside validation of a textbox

Question

I have an asp.net control textbox, clicking on which a jquery timepicker appears and user can select any time.But I want to validate the selected time so that it is one hour greater than the current time in the client side. I mean when textbox value will be changed it should be validated. Can anyone help me how to do this?

Answer 1

The input that the client's selection goes into will have an id. Do

$('#that_id').change(function() {
Validation Code/////
})
