var statusTimerId; var status = "OK"; //checks status every minute as long as it is "OK" function checkStatus () {   if(status == "OK"){     alert("Status OK");     statusTimerId = setInterval(checkStatus, 60000);   } else {     alert("Status Failed");   } } statusTimerId = setInterval(checkStatus, 60000);
