JQUERY :

var lastTypedTime = new Date(0); // it's 01/01/1970
var typingDelayMillis = 5000; // how long user can "think about his spelling" before we show "No one is typing -blank space." message

function refreshTypingStatus() {
    if (!textarea.is(':focus') || textarea.val() == '' || new Date().getTime() - lastTypedTime.getTime() > typingDelayMillis) {
        typingStatus.html('No one is typing -blank space.');
    } else {
        typingStatus.html('User is typing...');
    }
}
function updateLastTypedTime() {
    lastTypedTime = new Date();
}

setInterval(refreshTypingStatus, 100);
textarea.keypress(updateLastTypedTime);
textarea.blur(refreshTypingStatus);
