60、页面背景花瓣效果

脚本说明:

把如下代码加入<body>区域中

<script Language="javascript">

function a(x,y,color)

{document.write("<img border='0' style='position: absolute; left: "+(x+300)+"; top: "+(y+200)+";background-color: "+color+"' src='px.gif' width=1 height=1>")}

</script>

<script>

 

for(t=1;t<=360;t++){

lo=200 * Math.sin(2 * (Math.PI / 180) * t);

x = lo * Math.cos((Math.PI / 180) * t);

y = lo * Math.sin((Math.PI / 180) * t);

a(x,y,"#000000");

lo=200 * Math.cos(2 * (Math.PI / 180) * t);

x = lo * Math.cos((Math.PI / 180) * t);

y = lo * Math.sin((Math.PI / 180) * t);

a(x,y,"#ff0000");

}

</script>
