Answer 1

 function insertOption(dropDownList, itemText, itemValue)
  {
  var elSel = document.getElementById(dropDownList);
  var elOptNew = document.createElement('option');
  elOptNew.text = itemText;
  elOptNew.value = itemValue;
  elSel.add(elOptNew); // IE only
  }
    
  function clearOption(dropDownList)
  {
  document.getElementById(dropDownList).options.length = 0;加上引号
  }
</script>

Answer 2

document.getElementById(‘dropDownList’).options.length = 0;

Answer 3

dropDownlist本來就是傳過來的，不用加吧
