In this video I have shown how you can validate a simple HTML form using javascript with the help of PHP front end.
The form is with email and mobile validation also.
The PHP page is run with the help of XAMPP Server. Please go to my videos to get how to install XAMPP server in Windows PC.


<script type="text/javascript">
function validate() {
 var name = document.forms["myform"]["name"].value;
 alert("Please enter the name");
 return false;
 var email = document.forms["myform"]["email"].value;
 alert("Please enter the email");
 return false;
 var re = /^(?:[a-z0-9!#$%&amp;'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&amp;'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])$/;
 var x=re.test(email);
