How can I get the index of one of my class? I'm reading all in
docs.jquery.com and found nothing
    $("#new-criteria").click(function(){
        $last = $('#thefilter .qz-tablefield:eq(1)')
            .clone(true);
       <b>index </b>= 1; <font color="#663300">// here, how to get
the index of "this"?</font>
        $('#qz-criteria .qz-tablefield:eq('+<b>index</b>+')').after($last);
    });
Thanks
