迟到处罚通告怎么写:鼠标跟随文字代码

最近想在QQ空间里．搞一个鼠标跟随文字代码．可是做出来放上去的时候却弹出，，，代码过长
<style>.spanstyle {position:absolute;visibility:visible;font-size:9pt;color:#cccc00;}</style>
<script language='javascript'>
var x,y;var step=20;var flag=0;var delay=15;var timer;var message="欢迎来到动感小猪的空间";var xpos=new Array();var ypos=new Array();message = message.split("")
;for (i=0;i<=message.length-1;i++)
{
xpos[i]=0;
} for(i=0;i<=message.length-1;i++) {
ypos[i]=0;
}function handlerMM(e)
{
x = (document.layers) ? e.pageX : document.body.scrollLeft+event.clientX;
y = (document.layers) ? e.pageY : document.body.scrollTop+event.clientY;
flag=1;
}
function makesnake()
{
if (flag==1 && document.all)
{
for (i=message.length-1; i>=1; i--)
{
xpos[i]=xpos[i-1]+step;
ypos[i]=ypos[i-1];
}
xpos[0]=x+step;
ypos[0]=y;
for (i=0; i<=message.length-1; i++)
{
var thisspan = eval("span"+(i)+".style");
thisspan.posLeft=xpos[i];
thisspan.posTop=ypos[i];

}
}
else if (flag==1 && document.layers){
for (i=message.length-1; i>=1; i--)
{xpos[i]=xpos[i-1]+step;
ypos[i]=ypos[i-1];
}
xpos[0]=x+step;
ypos[0]=y;
for (i=0; i<=message.length-1; i++)
{
var thisspan = eval("document.span"+i);
thisspan.left=xpos[i];
thisspan.top=ypos[i];
}
}
timer=setTimeout("makesnake()",delay)
;
}for (i=0;i<=message.length-1;i++)
{
document.write("<span id='span"+i+"' class='spanstyle'>");
document.write(message[i]);
document.write("</span>");

}if (document.layers)
{
document.captureEvents(Event.MOUSEMOVE);
}
document.onmousemove = handlerMM;makesnake()</script>

大家有什么办法帮下我吗
