Assuming multiSelect is the select DOM object (obtained by document.getElementById for instance), then resultString will be the string you are looking for.

 var resultArray = [];
 for(var i=0; i < multiSelect.options.length; i++) {
     if (multiSelect.options[i].selected) {
         resultArray.push(multiSelect.options[i].value);
     }
  }
  var resultString = resultArray.join(",");
