Hi,

my scenario is as follows:

I have a registration form (non ajax) and want to add a link that checks the
availability of the username
(i.e., if it has already been taken) via ajax.

So I need a way to get the value of a form field without submitting the
form. Ideally the value of the form field
should be read (or it's model updated) when the ajax link is clicked.

Is there a convinient way to achieve this behavior.

Best regards,
Conny
