Clearing TEXTAREA After AJAX Submit

Howdy,

This is one of those simple questions that is hard to search and find an answer for, probably because most people just 'get it'.

Well, I have what I hope is a simple one.

I have the following:

<% form_remote_for(:chat_message, :url => chat_messages_path(@chat), :update => 'message') do |f| %> <%= f.text_area :message %> <%= submit_tag "Send" %> <% end %>

Works all fine and dandy but when I submit, the data is sent but I would like the text area to be blanked out again. It contains the submitted text.

What am I doing wrong?

Thanks, H

Hunter,

Add an html id to your form_remote_for() and then in your RJS file:

page.call 'Form.reset', 'your_form'

Hope this helps.

Contradicting Zack's answer, here's a snip from my post "How to chat":

  form_remote_for( :chat,          :url=>{ :action=>:utter },         :html=>{ :id => 'chat_panel_'+panel_id.to_s,                  :style => 'display:inline' },       :update=>'panel_'+panel_id.to_s+'_new_content_script',      :loading=>load,     :complete=>comp,        :after=>"chat_utterance.value='';"     ) do |f|

Note the line :after => "chat_utterance.value='';". If you don't want to reset your entire form, you can just zilch out the one TEXTAREA. And my code zilches punitively, regardless if the submission worked.

New question: How to do that with either RJS and/or Unobtrusive JavaScript?

(Assuming raw JavaScript is, what, distasteful? :wink:
