// Use function validate such that the form elements are checked if they are filled or not.. Required field are given id value of 
// form element this way =>  <input type=text name=username id=Username_required>
// here first part of id before underscore ie, Username is used to display on alert and _required part is to know if the element is required or not....
// if an element is optional then just ignore this convention...
// id is used, because this way you just have to change your working code by changing id, not the name attribute of field...
