A way to make html form disappear?

Use Ajax, with JQuery

http://api.jquery.com/jQuery.ajax/

Create a div for the response (#response_content), and in the callback of the function do something like

$("#form_id").hide();
$("#response_content").html(data);

Use JavaScript and set the form to display:none; (CSS)

And then add a div layer with your output.
