Submitting form with "Enter" instead of button click on ie8 or ie7 triggers live submit event twice.

Run the following using ie8 and you will see the event triggered twice. Run it in any other browser and it is triggered only once.

IE 6 is also affected

[boushley]

I can confirm that this is not the case for a normal submit handler and that it also persists in the GIT 0 version of jQuery.

Not a regression.

[iliakan]

That's because of a tricky IE behavior.

When a user submits by pressing enter and the form has more than one text/password input field *and* there is a visible image/submit then IE generates onclick on the submit.

Hence, the special.submit catches both click and keypress.

The patch skips keydown if it knows that IE will throw click. Fixes the issue in IE 6,7,8.

related to #6667?

[iliakan]

Don't think it is related. Also, #6667 appears to be fixed in 1.4.4, while #7444 is not fixed.

P.S. And yeah I know that's crazy.

I have experienced the same problems. This happens because the browser (not only IE, i have tested IE 6-8, Firefox 3.6.8, Opera 11.01, Chrome 10, Safari 5.0.4), when user press key "Enter" in text/password input field, then the browser after keydown/keypress/keyup events send "click" event to the first submit/image button. That's why handler is called twice.

If there are any alternatives for bypassing this problem?

[paulrpayne]

Is this ever going to be fixed on new releases, or are you waiting for ie to die? My workaround no longer works with the latest jQuery.

[rrafal@…]

I run into the same bug. I'm using the latest version of jQuery (1.6.4) and testing with IE7 and IE8. iliakan's description of the problem is what I see too.

Please help!
