script language="javascript"
function color(e)
{
switch(e.srcElement.id){ //获得标记的id
  case "first":
   document.getElementById("first").className="red"; //修改文字的样式
   break;
  case "second":
   document.getElementById("second").className="blue";
   break;
}
}
function clearText(e)
{
switch(e.srcElement.id){
  case "first":
   document.getElementById("first").className="black";
   break;
  case "second":
   document.getElementById("second").className="black";
   break;
}
}
/script
