停止事件冒泡到 Chrome 浏览器以进行 alt-keypress

Question

(Encountered while writing this script )

Relevant code:

window.keyPressEventLambda=function(key,callback){ //just a lambda function wrapper so I can generate handlers on the fly
return function (zEvent) {
        if (zEvent.altKey  && ( zEvent.which == key.charCodeAt(0)||zEvent.which == key.toUpperCase().charCodeAt(0))) {
            callback(this.id);
            return false;
        }
        return true;
}
}

Use case:

$("textarea").live("keydown",keyPressEventLambda("C",function(id){/*blah blah blah */})

So, if I use Alt - C , the callback function runs itself.

Now, due to the return false; , bubbling is suppressed and everything is handy-dandy within the page itself.

But, Chrome (20.0.1128.0 or 19.0.1084.41 on Windows), still captures the alt key as a Chrome browser shortcut, and, since no shortcut actually exists for Alt - C , it fails and makes an annoying "ping" sound.

It works fine for Ctrl -shortcuts, but I don't want to use these since most of the Ctrl -shortcuts are taken.

Is there any way to prevent the browser from getting angry at my script?

This is a known Chrome-issue. See http://code.google.com/p/chromium/issues/detail?id=105500
