The closest you're going to get to a ping in JS is using AJAX, and retrieving the readystates, status, and headers. Something like this:

url = ""
ping = new XMLHttpRequest();    
ping.onreadystatechange = function(){

    document.body.innerHTML += "
" + ping.readyState;

    if(ping.readyState == 4){
        if(ping.status == 200){
            result = ping.getAllResponseHeaders();
            document.body.innerHTML += "
" + result + "
";
        }
    }

}
ping.open("GET", url, true);    
ping.send();

Of course you can also put conditions in for different http statuses, and make the output display however you want with descriptions etc, to make it look nicer. More of an http url status checker than a ping, but same idea really. You can always loop it a few times to make it feel more like a ping for you too :)
