Prevent users from submitting a form by hitting Enter

Question

I have a survey on a website, and there seems to be some issues with the users hitting enter (I don\'t know why) and accidentally submitting the survey (form) without clicki

This has worked for me in all browsers after much frustration with other solutions. The name_space outer function is just to stay away from declaring globals, something I also recommend.

$(function() {window.name_space = new name_space();}); //jquery doc ready
function name_space() {
    this.is_ie = (navigator.userAgent.indexOf("MSIE") !== -1);

    this.stifle = function(event) {
        event.cancelBubble;
        event.returnValue = false;
        if(this.is_ie === false) {
            event.preventDefault();
        }
        return false;
    }

    this.on_enter = function(func) {
        function catch_key(e) {
            var enter = 13;
            if(!e) {
                var e = event;
            }
            keynum = GetKeyNum(e);
            if (keynum === enter) {
                if(func !== undefined && func !== null) {
                    func();
                }
                return name_space.stifle(e);
            }
            return true; // submit
        }

        if (window.Event) {
            window.captureEvents(Event.KEYDOWN);
            window.onkeydown = catch_key;
        }
        else {
            document.onkeydown = catch_key;
        }

        if(name_space.is_ie === false) {
            document.onkeypress = catch_key;    
        }
    }
}

Sample use:

$(function() {
    name_space.on_enter(
        function () {alert('hola!');}
    );
});
