You can't forbid anything using client-side scripting.

You should not use client-side scripting for this purpose.  Any method
you use in the client to screen out bad input can be circumvented but a
malicious user.  A check in the client can be helpful to the user,
because it can give very rapid feedback out malformed data, but it can't
be relied on to ensure only valid input is sent to the server.

You have to ensure that this is harmless.  The server code must be
designed so that it is unaffected by multiple submissions or reloads.

In short, this is not really a comp.lang.javascript question.

Once you clicked the submit, the request is on its way to the server.
Your browser waits for the response.
What the user does in the meantime (and how the browser handles it) 
won't stop the posted request to the server.

You can catch the mouse and keyboard events in the document if you want.
Just attach an eventlistener for all mouse events and keyboard events 
you want to catch, and make sure they don't propagate.
for example: keypress keydown events for keyboard
mousedown click etc for mouse.
Also look up: e.stopPropogation and e.preventDefault

I don't think you can avoid that.
I also fail to see why you WANT to forbid that.

None.
There isn't a magic regular expression that filters "all bad stuff" out, 
because "bad" depends on the usage.
You have to think about SQL-injection, cross site scripting, etc, etc.
What is OK in one situation, is not in the next.
So do it right, and handle all situations appropriately.

Why are you afraid of that?
Why care?
