Ajax Registration Program
In this Ajax Registration
program you will learn how to validate the user registration through ajax
call and then display the alert massage if no values are provided in the
username and password fields.
When a user input user Id and password and press Register
button , method 'call_Register()' will make ajax call. If the value
returned from the server is "yes" the alert box will show 'Welcome for
Register' otherwise it will show ' the Invalid Id/password please enter the
Id/password!'.

function postRequest(strURL){
var xmlHttp;
if(window.XMLHttpRequest){ // For Mozilla, Safari, ...

xmlHttp.open('POST', strURL, true);
xmlHttp.setRequestHeader('Content-Type',
'application/x-www-form-urlencoded');
xmlHttp.onreadystatechange = function(){
if (xmlHttp.readyState == 4){
updatepage(xmlHttp.responseText);
}
