[jQuery] JQuery for retrieving form fields?

[jQuery] JQuery for retrieving form fields?

Sorry if this seems totally inane, but is anybody using JQuery for
retrieving the values of form fields?
For the life of me I can't figure out how to get the value of a form
field via a JQuery lookup, see the testcase below.
Is this a bug, or does the problem lie between the headset?
