Howto get javascript value in HTML form

I've got jquery using the sortable plug in.

I'm using the following function to get the values.

    $(function() {
            $( "#sortable" ).sortable(开发者_Go百科{
                placeholder: "ui-state-highlight"
            });

        });

    function overzicht(){
            var regel = '';
            $('ul#sortable li').each(function(index) {
            regel += $(this).attr('id').replace(/ /g, "") + ',';
          });
        }

<ul id="sortable">
        <xsl:for-each select="//regels/item">
        <li style="list-style:none; vertical-align:middle; min-height:50px" id="{veld[3]}" class="ui-state-default">
</li>
        </xsl:for-each>
        </ul>

How do I get the "regel" value in a HTML form like this?

<form name="cartForm" method="post" action="edit_bestellijst.asp">
  <input type="hidden" name="act" value="update" />
  <input type="hidden" name="artNr" value="***regel values***)" />
</form>

I'm using a bit XSL. Can someone please help me?

after the each loop you should write :

$("input[name='artNr']").val(regel);
