It has been said that too much power can be dangerous. That saying is befitting when it comes to enhancing or creating Web widgets with client-side scripts. Web widgets, as you might recall from Part 1 (http://www.opensourcetutorials.com/tutorials/Design-And-Layout/Usability/web-widgets-part-1/page1.html), are controls used in Web forms, dialogs, and wizards to elicit information from users.

Jodi Bollaert describes some common usability problems associated with client-side scripts and Web widgets, and suggest ways to avoid them. Read Using Web widgets wisely, Part 2 here.
