Ajax form

An Auto Complete form - Ajax Magic in Drupal 7

An Autocomplete form: We all know we are lazy by nature and we want everything on their hand without any efforts or hard-work. This lead to thinking peoples to search for new technologies. So an auto-complete thing works the same in which people just put some data in a textfield and all the things will be done automatically (depends on input data). It's an Ajax thing which is used to exchange data from the server at the client site.
