• This form uses the larryband Transport to communicate with the server without refreshing the page.
• With the larryband Transport (AJAX) your form automatically performs both client side and server side validation.
• Here are the Client/Server rules:
  • Note: This example will only work on the larryband web server. It will not work in your local copy.
  • The fields are all required and the client side code enforces the data entry.
  • After the client side test is passed, the server performs the following checks.
  1. Checks that the login name is available. In this example, the following names are not available: "Joe", "Jane", "George", "Judy". All other should pass the test.
  2. Checks that the two passwords are identical. This could, of course, be done as a client side check, but we're demonstrating the handling of multiple server side validation errors.
• On success, the form calls a developer-defined function. In this form, an alert box displays success .
• On failure, the form displays an error message.
