Enlazar formulario login ajax con php scripts

Publicado por rafael cardona pagman6@hotmail.com (1 intervención) el 15/07/2011 18:36:21
Hola a todos amigos del foro.

En enstos momentos estoy realizando un proyecto y tengo problemas al enlazar el formulario de login que obtuve del template [url="http://www.fileden.com/files/2007/6/13/1173901//constellation.zip"]constellation admin skin[/url] que usa una interfaz ajax para hacer el proceso de logueo.

La cuestion es que no entiendo como funciona del todo (tengo poca experiencia con el AJAX y el Javascript), no se donde debo poner la pagina a donde debe realizarse el logueo (control.php?action=login) ni donde poner la pagina de redireccion (panel-control.php)

aca les dejo el codigo en html que poseo en el archivo login.html:
