Display eForm before send

Is there a way to display an eForm before sending it? I know you can show the results on the page using the report chunk and specifying in the snippet. On this stage is it possible to e-mail gathered data?
What I'm looking for is:
1) fill in the form
2) press "next" which validates the form
3) display the results in a page - possibility to go back if needed
4) press "send" wchich e-mails gathered data or "save as pdf" using tcpdf.

Is it possible to do this using an eForm and not complicating it too much?

I used Javascript to do this, hiding the form section and showing the values that had been entered into the fields. A set of buttons allowed a return to the form view (hiding the review section) and the submit button.

You could also have the initial form (no mail) submit to a thank-you page containing another eForm snippet that pre-populates the fields from the POST. You can allow the fields to be edited there, or disable them and have a button returning to the original form for editing.

Hi Susan, thank you for your reply. It's a really good idea to do it with with Javascript/jquery, I haven't thought about this. As for the second solution I'm not sure if I understand well what you mean. Could you give an example?
