[jQuery] Help getting a variable

[Dave Maharaj :: WidePixels.com]

I am trying to get 2 variables....but not sure how I can get them from the
form
 
i have hard coded 
$(this).ajaxSubmit({
    type:    'post',
    url:      '/joesmith/update/profile',
    data:     queryString,
                target:   '#profile',
    success:     function() {alert(queryString);} 
            });
 
but where joesmith and profle are coded into the url: those are 2 variables
i need to pass to the script
joe smith is in the browser url but profle is from a link.
 
Not sure how I can get those variables passed into the script.
The form ID is not editable, cant add _joesmith or anything
 
Ideas?
