url형식에 자동링크 가능한가요?

<script>
function autolink(id) {
        var container = document.getElementById(id);
        var doc = container.innerHTML;
        var regURL = new RegExp("(http|https|ftp|telnet|news|irc)://([-/.a-zA-Z0-9_~#%$?&=:200-377()]+)","gi");
        var regEmail = new RegExp("([xA1-xFEa-z0-9_-]+@[xA1-xFEa-z0-9-]+\.[a-z0-9-]+)","gi");
        container.innerHTML = doc.replace(regURL,"<a href='$1://$2' target='_blank'>$1://$2</a>").replace(regEmail,"<a href='mailto:$1'>$1</a>");
}
</script>
