Ondra,

Therefore, I am afraid that if you need a consistent behaviour of
Enter, there are only two solutions:

(a) single-submit form;
(b) JavaScript.

Yes, I understand your point here....

Even the concept of multiple-submits itself isn't necessarily supported
100%, but I'm going to err in favor of my little hidden 2x2.gif and test it
across several newer browsers and then accept it as working. And as a

However, as mentioned here multiple-submit is a workaround at best. HTML provides no "built-in" support for the concept. Obviously you wouldn't want to completely rely on the hidden image button workaround, just like you wouldn't want to completely rely on multiple-submit itself.


If designed correctly your application can benefit from this workaround. If your "default" action could have undesirable effects then it should be backed by a confirmation panel anyway.

worse-case I have coded all submit actions to produce recoverable events if
a fault were to happen. And I'm using that handy tip to remove it from the
tab-order as well (thanks again guys).


Did I mention it has to work in a micro-browser on the University's PDA/Cell
Phone(s)? Sure to turn the simplest app into a four week project :)


Thanks for your input - everyone.

So if one had the need to make it appear that the "default" button

possible to create this "hidden" image button at the top of the
form and bind its action to the same action as the one you want for
your "default" action?

Chuck or someone with greater experience may correct me, but I do fear the behaviour of a multi-submit form when an Enter is pressed in some field is undefined at the HTML level, and essentially each browser may interpret the event in a different way (say, browser A would always take the very first submit of the form, whilst browser B would always take the first button after the textfield in which the Enter was pressed).

Therefore, I am afraid that if you need a consistent behaviour of
Enter, there are only two solutions:

(a) single-submit form;
