An applet is a program designed to be executed from within another application. Unlike an application, applets cannot be executed directly from the operating system.

Scripts refers to the contents of a computer programming language.

Guidelines for overcoming access barriers

  1. Provide equivalent information on an alternative accessible page if content cannot be accessed because scripts, applets or other programming objects are turned off or not supported. APPLETS EXAMPLE 1
  2. If an alternative text version exists, ensure that you update both versions when changes are made.
  3. Ensure programming elements such as scripts and applets are directly accessible or compatible with assistive technologies. SEE MULTIMEDIA EXAMPLE 3
  4. Ensure that event handlers are input device-independent for applets and scripts. APPLETS EXAMPLE 3
  5. When linking to a popup using Javascript, make sure that you have catered for users who have Javascript disabled. APPLETS EXAMPLE 4
