<meta charset="utf-8">
<body>
<script language = javascript>
todatDate = new Date();
date = todayDate.getDate();
month = todayDate.getMonth()+1;
year = todayDate.getYear();
sentence = ""+year+"年"+month+"月"+date+"日";
Balises = "";
Taille = 40;
Midx = 100;
Decal =0.5;
charNum=sentence.length;
for(i=0;i<charNum;i++)
{
Balises=Balises+'<div id="L"'+i+'style="width:3;font-weight:bold;position:absolute;top:320;left:400;z-index:0">'+sentence.charAt(i)+'</div>';
}
document.write(Balises);
Time=window.setInterval("Alors()",10);
Alpha=5;
I_Alpha=0.05;
function Alors(){
Alpha=Alpha-I_Alpha;
for(j=0;j<charNum;j++)
{
Alpha=Alpha+Decal*j;
cosine=Math.cos(Alpha1);
Ob=document.all("L"+j);
Ob.style.posLeft=Midx+100*Math.sin(Alpha1)+400;
Ob.style.zIndex=20*Cosine;
Ob.style.fontSize=Taille+25*Cosine;
Ob.style.color="rgb("+(12+Cosine*60+50)+","+(127+Cosine*60+50)+",0)";
}
}
</script>
</body>
</html>
这段代码输出不出来，还请各位大佬帮我看看提点提点！！在此拜谢！！！！
