upload_progress_update_bar_js(percent=nil)

public

Javascript helper that will create a script that will change the width of the background progress bar container. Include this in the script portion of your view rendered by your upload_status action to automatically find and update the progress bar.

Example (in controller):

  def upload_status
    render :inline => "<script><%= update_upload_progress_bar_js %></script>", :layout => false
  end

# File actionpack/lib/action_view/helpers/upload_progress_helper.rb, line 378
      def upload_progress_update_bar_js(percent=nil)
        progress = upload_progress
        percent ||= case 
          when progress.nil? || !progress.started? then 0
          when progress.finished? then 100
          else progress.completed_percent
        end.to_i

        # TODO do animation instead of jumping
        "if($('#{progress_bar_id}')){$('#{progress_bar_id}').firstChild.firstChild.style.width='#{percent}%'}"
      end
