javascript for automating the response email function

Is there a javascript for livecycle designer form that will automate the function of a return email with form attached?
I want the people filling out this form from our website to just click the submit button
and go. The 'email submit button' provided by livecycle designer only gives the end user the
address, subject and body content of the email. The end user still has to open their email and compose the message themselves. As well as attaching the form to be returned.
Is there any way to automate this function with a javascript? Any help with this would be greatly appreciated.
