Here is the link to custom.js

And for validation file login.php link is

The data argument is a response from your login.php script as json object. For example, if you put this in your login.php script:
[php]echo ‘{“response”:“Success”,“status”:“Logged in”}’;[/php]
then you can do this in your javascript:
$.post("login.php", {username:user.val(), password:pass.val()}, function(data){
if(data){
alert(data.status);
}
});
authenticate login using jquery
For this you have to create two file first file will be simple html file having login form(login.html) and second file is a php file having login authentication logic(logincheck.php)
First file login.html
[php]
// save code as login.html
Username:
Password:
[/php]
second file logincheck.php
[php]
// save code as logincheck.php
$is_ajax = $_REQUEST[‘is_ajax’];
if(isset($is_ajax) && $is_ajax)
{
// you can put here your logic for checking user name and password which is stored in
// your database
// here i have set static values for testing
$username = $_REQUEST['username'];
$password = $_REQUEST['password'];
if($username == 'sanjay' && $password == 'sanjay')
{
echo "success";
}
}
[/php]
by default i have set valid user detail as
user name : sanjay
password : sanjay
I hope this will helpful for you
Thanx
