脚本说明:
第一步：把如下代码加入<body><center><script language=javascript src="../js/shang.js"></script>
区域中
<STYLE TYPE="text/css">
<!--

BODY{
overflow:scroll;
overflow-x:hidden;
}

.s1
{
  position  : absolute;
  font-size : 12pt;
  color     : blue;
  visibility: hidden;
}

.s2
{
  position  : absolute;
  font-size : 20pt;
  color     : red;

  position  : absolute;
  font-size : 16pt;
  color     : gold;

}

.s4
{
  position  : absolute;
  font-size : 14pt;
  color     : lime;
	visibility : hidden;
}

</STYLE>

第二步：把如下代码加入<body><center><script language=javascript src="../js/shang.js"></script>
区域中
<DIV ID="div1" CLASS="s1">*</DIV>
<DIV ID="div2" CLASS="s2">*</DIV>
<DIV ID="div3" CLASS="s3">*</DIV>
<DIV ID="div4" CLASS="s4">*</DIV>

var nav = (document.layers);
var tmr = null;
var spd = 50;
var x = 0;
var x_offset = 5;
var y = 0;
var y_offset = 15;

if(nav) document.captureEvents(Event.MOUSEMOVE);
document.onmousemove = get_mouse;

function get_mouse(e)
{    
  x = (nav) ? e.pageX : event.clientX+document.body.scrollLeft;
  y = (nav) ? e.pageY : event.clientY+document.body.scrollTop;
  x += x_offset;
  y += y_offset;
  beam(1);     
}

function fade(n)
{
  if(n>0) 
  {
    if(nav)eval("document.div"+n+".visibility='hidden'");
    else eval("div"+n+".style.visibility='hidden'"); 
    n--;
    tmr=setTimeout("fade("+n+")",spd);
  }
  else clearTimeout(tmr);
}
