There are a few. The $.ajax methods will end up doing 90% of your
work. I'll show you a pretty quick process demonstrating checking if
an email address is registered.
First, the PHP servlet page, check-email.php:
<?php
echo json_encode(
array('success' => mysql_num_rows( mysql_query( 'SELECT * FROM
`user_emails` WHERE `email` = "'. $_REQUEST['email'] .'" LIMIT 1' ) )
== 0 ? true : false)
);
?>
Now the HTML:
<label>Enter your desired eMail account name to check availability</
label>
<input id="user-email" type="text" size="15"/>
<span id="status" style="display:none"></span>
<button id="submit" value="Check Now">Check Now</button>
And finally the jQuery
$(function(){
$('#submit').click(function(){
$.get('check-email.php', {email: $('#user-email').val()},
function(data){
var status = $('#status');
if (data.success) status.text('eMail is Available!').css
('color', 'green');
else status.text('eMail is NOT Available!').css('color',
'red');
}, 'json');
});
});
I hope that gave you kinda an idea of how you can use jQuery for RPCs.
