How to overwrite or remove key events, that is on a website? I’m writing a script for GreaseMonkey and I want to make event on Enter button, but when I press the ENTER button, it triggers function on website.

EDIT 1: Here is the website, that I need to do this http://lockerz.com/auth/express_signup

Answer 1

One of these two should do it for you. I used the first one, although someone on SO told me the second one will work also. I went for the hammer.

Sorry, first one wasn’t a cut and paste answer. I use using it to return up/down arrow control on a website. I changed it so that it identifies keycode 13 instead.

(function() {
    function keykiller(event) {
        if (event.keyCode == 13 )       
        {
            event.cancelBubble = true;
            event.stopPropagation();            
            return false;
        }
    }

    window.addEventListener('keypress', keykiller, true);
    window.addEventListener('keydown', keykiller, true);
})();
