I have a form where the user will type in some text in a text area. When this form gets submitted, all of the info gets pushed into a MySQL table. The text area in question can have HTML and special formatting. I want to create a preview div for this. I can use observe_field to preview the formatting as they type, but I''d rather have it set so that they can click a "Preview" link and AJAX will update the DIV after formatting the info in the text area. My question is this: how do I get the information in the text_area to the AJAX action called by my preview link? - David -------------- next part -------------- An HTML attachment was scrubbed...

For example, <%= observe_field(id_of_field_to_watch, :url =>{:action => ''update_action'', :id => ''div_to_update''}, :with => ''content'' ) %> will make the content of the field being observed available in the ''update_action'' action in the controller via params[:content] hth, Bill
