傳遞散列鍵向控制器

Question

我有這樣的代碼中的Rails 2.X：

<div class="label-field-pair"> 
    <label><%= t('select_a_course_batch') %></label> 
    <div class="text-input-bg"> <%= select :fees_submission, :batch_id, @batches.map { |c| [c.full_name, c.id] }, 
     {:prompt => "#{t('select_a_batch')}"}, 
     {:onChange => "#{remote_function(:url => {:action => "update_fees_collection_dates_voucher"}, :with => "'batch_id='+value")}"}%> </div> 

爲的onChange動作。我想通過散列密鑰（c.fullname）到遠程控制器update_fees_collection_dates_voucher代替散列值（c.id）..用''batch_id ='+ key「替換''batch_id ='+ value」似乎不起作用。有任何想法嗎？謝謝！

這不是工作？

{:onChange => "#{remote_function(:url => {:action => "update_fees_collection_dates_voucher"}, :with => "'batch_id='+ $(this).html()}"}%>
