JavaScript is a compact, object-based scripting language for developing client and

that users enter valid information into a form. Without any network transmission, an HTML
page with embedded JavaScript can interpret the entered text and alert the user with a
message dialog if the input is invalid. Or you can use JavaScript to perform an action
(such as play an audio file, execute an applet, or communicate with a plug-in) in response
to the user opening or exiting a page. .....
