I am using the code posted in this answer to "clone" my form:

http://stackoverflow.com/questions/4400592/jquery-clone-form-and-increment

However, what I really want to do is to take two values from the current form, add it in another div, hide the current form, then show the empty cloned form.

We allow people to register other people for courses. I want to allow them to enroll multiple participants at one time. The UI should have one and only one form but when they enter a person's information and click a button to add another person, they should be able to see a list of people that they have previously registered and have the capability to remove them from the list.

Here is a URL to the basic beginnings with comments on what needs to be done: http://www.scic.com/files/formclone/index.html

I think you can keep the template of that form in a string with a placeholder to append a common counter.

x++; // to avoid having the same name
$("<input />").attr({ "name":"field1name"+x, "value":value1 }).appendTo("#Another_div_div");
$("<input />").attr({ "name":"field2name"+x, "value":value2 }).appendTo("#Another_div_div");

$("form").hide();

$("form").clone().show().appendTo("body");

var value1 = $("#field1_ID").val(); // input or select or textarea
var value2 = $("#field2_ID").val(); // input or select or textarea

Open in new window

How do I account for the change in names, based on which form it is?

ID is unique in a document.
If your form have a name or an ID (or why not a class) you can try to get the right field by ID (if you've more than one field with the same ID) by providing the "context"
the context is your form

for example :

var value1 = $("#field1_ID", "#form_to_clone").val(); // input or select or textarea
var value2 = $("#field2_ID", "#form_to_clone").val(); // input or select or textarea

it not necesaarily a form, it could be any other containter (context)

// 1. Clone the participant div 
          var clone_participant_div = $(".participant", "#content").clone();
          clone_participant_div.insertAfter("#voucher_form");
          // 2. Add the entered firstname + lastname to the 
          //    participants_name span 
          $(".participants_name", clone_participant_div).html( $("#lastname").val() + " " + $("#firstname").val() );
          $(".remove_participant", clone_participant_div).html( "remove" );
          // 3. Bind a click handler for the remove button (span)
          //    to be able to remove the entry from the participants_list 
          //    and remove the form fields for the participant to be removed
          $(".remove_participant", clone_participant_div).click(function() {
              $(this).parent(".participant").remove();
          })

          // 
          $("#voucher_form").hide();

You're getting close. The last att div needs to be hidden, not the form.
I also changed to show it before the voucher form, as shown in the HTML.

Never used that jsFiddle before but it looks great. Got everything working, just a few more little gotchas that I think I can handle on my own.

Thanks a million.
