text_are_tag without submit_tag

Hi all,

It must be simple stuff. I am trying to put an input text area

- that submits when a user presses Enter without a submit button and - resets itself for a new input after Enter.

<% form_remote_tag (:url => {:action => 'my_action'}, :update => "area") do %> <%= text_area_tag 'my_input', " ", :rows =>2, :columns => 12,        :onclick => "$(my_input).reset()" %> <% end %>

What am I doing wrong? Thanks.

Sy
