Question

I want to update the value from a input/textfield with a calculated value from the cookie.It’s like a mini local cookie cart.
Saving and retrieving the json from the cookie is a piece of cake.
In my behavior I fail to make the following work:

I added a class for every node in the input field, it’s constructed like the example below.

Myid = 'webform_cart_nid_10';
formElement = $('.' + Myid);
console.log(formElement);

The html is quite nested and can be seen http://it2servu.be/broodjes/bestellen (if I may link?) .
the field whose value I want to update looks like this:

<input class="webform_cart_nid_10 webform_cart_nid form-text" type="text" id="edit-submitted-cart-item-cart-elements-10" name="submitted[cart_item][cart_elements][10]" value="0" size="3" maxlength="128">

Is contained in drupal output with severe div-itis.

    <div class="page clearfix" id="page">
     <div id="section-content" class="section section-content">
      <div id="zone-content-wrapper" class="zone-wrapper zone-content-wrapper clearfix">  
       <div id="zone-content" class="zone zone-content clearfix container-12">    
        <div class="grid-12 region region-content" id="region-content">
         <div class="region-inner region-content-inner">
          <div class="block-inner clearfix">
           <div class="content clearfix">
            <div class="node node-webform node-promoted view-mode-full clearfix ">
             <div class="field field-name-title field-type-ds field-label-hidden">
               <form class="webform-client-form" enctype="multipart/form-data" action="/broodjes/bestellen" method="post" id="webform-client-form-5" accept-charset="UTF-8">
                <div>
                 <fieldset class="collapsible form-wrapper collapse-processed" id="edit-submitted-cart-item-cart-elements">
                  <div class="fieldset-wrapper">
                   <div class="form-item form-type-textfield form-item-submitted-cart-item-cart-elements-10">
                    <input class="webform_cart_nid_10 webform_cart_nid form-text" type="text" id="edit-submitted-cart-item-cart-elements-10" name="submitted[cart_item][cart_elements][10]" value="0" size="3" maxlength="128">
...

probably it’s something stupid, I just can’t figure out what it is?

Your problem is with jQuery. If you pop open the console in Chrome and type jQuery, it returns the jQuery function. If you type $ it returns undefined. You have some sort of collision causing $ not to be set to jQuery.
