There are many ways to do this. At http://www.socmedia.com.my/lowyat/angie_oet/angie_oet.phps I am using jQuery library to bind 'onBlur' event at the text input and fire xmlhttprequest to the server and refresh the page. This example might not what you want. Just to show you one of thing that we can do. The easiest or straightforward way is just submit the form everytime onlur event occurred at the text input.
