optomeb, You could set it up so that if the user has JS, then the submit action gets blocked, but you does some XMLHTTPReq stuff to get the job done.
If there is no JS, then the submit will do it's magic.

[optomeb]

Action is required according to w3

On the server side, you'll hook them into the same functions, so you won't haveot know the difference.

optomeb, then also put onSubmit="return false"
Or something like that
but i dont know exact

[Klimapol]

montanarry, no
you'd attach an event listener
Cancel the event
And then do XHR stuff instead
Of course then you have to know how to use XHR and what to do with the response

[montanarry]

What?

[Klimapol]

Nothing about it "just works"

[montanarry]

Why cant he put event listener
If the html sends the form after enter
Then block it with the <form onSubmit="return false;">
I still bet 20 that it has to be this way

[Koplaf]

montanarry, That's an easy bet for you to make, being as none of us is on hand to collect.

montanarry,Using unobtrusive javascript also means not using html attributes to attach event handlers
