For the sake of demonstration, we have taken five countries only. function form Validation() function userid_validation(uid,mx,my) function passid_validation(passid,mx,my) function all Letter(uname) function alphanumeric(uadd) function countryselect(ucountry) function allnumeric(uzip) function Validate Email(uemail) function validsex(umsex,ufsex) Flowchart : Download the Validation code from here.
Shows you how to write a script that ensures your form is filled in correctly before it's sent to your server.
Understanding Java Script's request Animation Frame() method for smooth animations is a Java Script method for creating smoother, less resource intensive Java Script animations.

This tutorial will show you how to create a Java Script-enabled form that checks whether a user has filled in the form correctly before it's sent to the server. First we'll explain why form validation is a useful thing, and then build up a simple example form, explaining things as we go along.
The tutorial explores Java Script validation on submit with detail explanation.
Following pictorial shows in which field, what validation we want to impose.
At the end, there's a little exercise to keep you busy too!
