It is default browser behavior to hunt a form for jQuery(":submit") elements and trigger the first listed on the form, when the enter key is pressed.

this will look strange on debugger, because if you have a function such as onclick="handle(event);".

You go to the text field, hit enter, and you will see an "artifical" onclick event with being passed to your primary submit action for that form.

The surest way to be in-control of what happens, I would say, is not by means of onkeypress as explained above. I found that to not work in all cases. On soame cases the form onkeypress simply does not get triggered, and you do not have then the opportunity to return flase; / event.preventDefault();. I am not 100% sure of all cases that justfied the onkeypress not getting triggered, but I suspect framework code preventing event bubbling in some instances.

Ultimately, what is really happening is your form is being submitted by your browser default behavior on ENTER withing input text field. It is not the bubling of the event to the form that submits the form. That is the flaw of trying to handle the event on the form and preventing default behavior there. That might just be too late. And this is very easy to verify. If you tune youe inpu text and onkeypress always to event.preventDefault(). (A) you kill the textbox no text gets written on the texbox (B) The event still bubles up, but the browser does not submit the form anyway. So the most important element of all is: where is the browser aiming at when it acts with the default behavior?

So what you can decide instead is that what you will take control of where the browser unleashes its default behavior. You can direct it to a dummy button.

This is the one and only one mechanism I have found to be really reliable to be in control of what happens when you hit enter on a text field withing a form is to have on that form a well known artifical button, e.g.:

You get the idea, to make sure that the submit event is being routed by the browser to a button under your control.

You have to be careful, IE in particular is quirky. If not for IE, you could simply style your button as display: none. Because of IE, the browser will route the default submit action to a visible submit button, if one exists. Therefore, your button cannot be in display none. You have to make it logically visible, but phsysically invisible. For that you supress the border and give it an appropriate background for your application.

This method is 100% reliable.
