Week 5
- Browser incompatibilities--Different browsers support different versions of JavaScript, different object models, and different event-handling approaches. Failure to take these differences into account is a major source of scripting errors.
Browser bugs--Both beta and final releases of browser software contain bugs that can cause scripts to malfunction.
Bad input--Scripts must stand up to bad inputs from users, CGI programs, and other sources.
Bad design and coding--Scripts may be designed incorrectly or may contain undetected coding errors.
Unexpected events--External events, such as the closing of a window or the opening of a frame in a window of its own, may cause scripts to malfunction.
Unavailable resources--The unavailability of resources such as multimedia files, CGI programs, or database services may lead to errors.
Loss of state--Other errors result when different parts of Web applications get out of sync.
