Referencing an unnamed form

Referencing an unnamed form

Hi,
 
I am using the following system to create my forms :
 
<% using (Html.BeginForm()) { %>
 
Now I want to refer to the form in JQuery, but all the examples I can find refer to the form by it's name.  How do I refer to my form if it doesn't have a name?
 
 
Thanks,
 
Mike
