jQuery Combo Boxes (User Selection) / Text Validation

Question

Is there a way to have a text validation tool for jQuery such that:

Box 1: Hi Box 2: Automatically fills with Hi if Hi is entered in Box 1

In another case if,

Box 1: Bye Box 2: If the user enters Bye in Box 2 it says that they entered an invalid response

Also is it possible to have it such that if Choice A is selected in a a combo box it auto fills some of the text boxes and prevents the user from editing them?

Thanks,

You'll want to take a look at jQuery event handlers at jQuery Events/Bind.
