#有些時候page.call paramter work 不是很正常
page.call "get_details", "info-id", "message","{phone:5487895, mobile:9888565875}"
page.call("buildYUITreeView", "project_tree", @current_project.get_directory_contents(@current_project.local_path, 0))
#可以用這樣的方式去取代
page << "get_details('info-id','message','{phone:5487895, mobile:9888565875}')"
page << "buildUYITreeView('project_tree', #{@current_project.get_directory_contents(@current_project.local_path, 0))})"


      respond_to do |format|
        format.js {render(:update) { |page| page << 'alert("Wrong Nick");'}}
      end


  update_page do |page|
    page.insert_html :bottom, 'list', "
#{@item.name}

    page.visual_effect :highlight, 'list'
    page.hide 'status-indicator', 'cancel-link'
