currently, jsMsg only takes HTML as String for the message content.

I suggest the following change:

< messageDiv.innerHTML = message;

if (typeof message == 'string') {

		messageDiv.innerHTML = message;

}
else if (typeof message == 'object') {

		while (messageDiv.hasChildNodes()) // Remove old content
			messageDiv.removeChild(messageDiv.firstChild);
		messageDiv.appendChild (message); // Append new content

}
