Form validation normally used to occur at the server, after the client had entered all the necessary data and then pressed the Submit button.When you submit a form to a CGI program that resides on the server, it is usually programmed to do its own check for errors.If it finds any it sends the page back to the reader who then has to re-enter some data, before submitting again.We have simple div below each form input field with a unique respective ids.we use these divs to print errors after validating the form.For that you have to add name for the two submit buttons.And using that name we can prevent the _inclusion, while submitting the form through clicking "Save as draft" button.On click of submit button js function Formsubmition is triggered which submits the form using Cold Fusion.Ajax.submit Form method takes the values of all of the items in the form frm , and posts them to the file 'action.cfm.If the data entered by a client was incorrect or was simply missing, the server would have to send all the data back to the client and request that the form be resubmitted with correct information.This was really a lengthy process which used to put a lot of burden on the server.
