settimeout - Set and hold a variable in javascript -

i have 3 javascript functions:

function updatetest() {     if (totalmin == "0") {         coolvar = "start";     } else {         coolvar = "stop";     } } setinterval(updatetest, 1000)  var audvar = setinterval(function () {     cooltrigger() }, 60000);  function cooltrigger() {     updateaudio(coolvar); } 

i need design function checks state of coolvar same interval, updates html code once upon coolvar=start. should hold , not update variable 60 seconds , returns previous state.

function updateaudio(coolvar) {      var a_str;      if (coolvar == "start") {          a_str = '<audio autoplay source src="audio/coolsound.mp3" type="audio/mpeg"></audio>';      }      if (coolvar == "stop") {          a_str = '<!--coolsound go off @ 0:00 timer -->';      }      document.getelementbyid('audio_span').innerhtml = a_str;  }  //settimeout(updateaudio, 6000);  

at moment using current code, coolvar checked once every 60 seconds update a_str. wanted check coolvar every second update a_str once upon first triggering updateaudio.

what doing wrong? there way achieve this?
