Combine javascript with rails form

I am using javascript to select a file and then to show the file upload progress. I would also like to be able to modify other attributes of the file.

<script type='text/javascript'>
var swfu;

window.onload = function () {
swfu = new SWFUpload({
  upload_url : '<%= new_image_path_with_session_information %>',
  flash_url : '/flash/swfupload.swf',

        // Button settings
        button_image_url: "/images/TestImageNoText_65x29.png",  
        button_width: "75",
        button_height: "29",
        button_placeholder_id: "spanButtonPlaceHolder",
        button_text: '<span class="theFont">File</span>',
        button_text_style: ".theFont { font-size: 16; }",
        button_text_left_padding: 12,
        button_text_top_padding: 3,

  file_size_limit : '10000',
  file_types : '*.jpg',
  file_types_description : 'JPG Images',
  file_upload_limit : '0',
        custom_settings : {
            progressTarget : "fsUploadProgress"
        },

  file_queue_error_handler : fileQueueError,
  file_dialog_complete_handler : fileDialogComplete,
  upload_progress_handler : uploadProgress,
  upload_error_handler : uploadError,
  upload_success_handler : uploadSuccess,
  upload_complete_handler : uploadComplete,

        post_params : {
            authenticity_token : '<%= u form_authenticity_token -%>',
        },

  custom_settings : { 
    upload_target : 'divFileProgressContainer',
  },

  debug: false

   });
   };
 </script>

     <div style="margin: 0px 10px;">
<div>

    <%= form_for(@image) do |f| %>
        <fieldset>
            <div id="divStatus">Upload an image</div>
     <div class="field">
      <p>
      <b><%= f.label :state_id %></b><br />
       <%= f.collection_select :state_id, State.all, :id, :name %>
       </p>

            </div>
<div>
                    <span id="spanButtonPlaceHolder"></span>
                </div>
        </fieldset>
    <% end %>

</div>
<div id="divFileProgressContainer" style="height: 75px;"></div>
<div id="thumbnails"></div>


     </div>

At the bottom there is the familiar rails form, how can I include that value into the POST request?
