Answer 2

Answer:

Store the form's contents to a database file on the server

Explanation:

• Client-side operations and triggers are run in the browser on the client machine and are implemented in JavaScript. They are executed by the browser when they are invoked from the server.
• Interaction with HTML forms is one of the important aspect of client-side JavaScript  .
• JavaScript has an obvious advantage over server-based scripts for applications like : JavaScript code is executed on the client side, so there is no need to send the form’s contents to the server. Hence, relatively simple computations can be performed.
• Another common use of client-side JavaScript with forms is for validating form data before submission. If client-side JavaScript is able to perform all necessary error checking of a user’s input, no round trip to the server is required to detect and inform the user of trivial input errors.
• The alert() method in JavaScript  displays a virtual alert box.  to give a warning message to the users.
