[Javascript] Dynamically generate link from text being typed in textbox?

[David Yee]

Hi all.  I'm wondering is it possible to dynamically generate a link as text
is being typed into a particular text box.  Basically I want the link to
contain a GET variable name and value without submitting the form (the form
actually posts to another page).  And since I don't think you can have a
form within a form I'm hoping I can do it using Javascript.  Thanks!
