To submit a form with AJAX (without reloading the page), you can use the ajaxForm/ajaxSubmit functions from Ajax Form Plugin or the jQuery serialize function.
AjaxForm:
$("#theForm").ajaxForm({url: 'server.php', type: 'post'})
or alternatively:-
$("#theForm").ajaxSubmit({url: 'server.php', type: 'post'})
ajaxForm will send when the submit button is pressed. ajaxSubmit sends immediately.
Serialize Method:
$.get('server.php?' + $('#theForm').serialize())
$.post('server.php', $('#theForm').serialize())
