Prevent multiple initialization #251
Description
Apparently, it's easy to get things wrong and call timeago() multiple times on the same element. It would be great if the init function would in this case not set a new interval without clearing the old one, e.g. if you'd replace
if ($s.refreshMillis > 0) {
this._timeagoInterval = setInterval(refresh_el, $s.refreshMillis);
}
with
if ($s.refreshMillis > 0 && this._timeagoInterval == null) {
this._timeagoInterval = setInterval(refresh_el, $s.refreshMillis);
}
