I use the following code to submit a form and get a response using AJAX.
When the form has been submitted, a response in placed in placeholder div: "Successfully Saved"
Now you only ever see on response: "Successfully Saved"
I want the response to be APPENDED to the contents of the placeholder div, not to replace the contents.
So if a user submits the form 10 times they should see 10 messages: "Successfully Saved" -- each one under the one before it.
