朋友给我一组网络代码，我不会用。大家试试用得到吗？用到记得教我。星空背景第一步：把如下代码加入到<body>区域中
<script language="JavaScript">
<!--
SmallStars = 30;
LargeStars = 10;
SmallYpos = new Array();
SmallXpos = new Array();
LargeYpos = new Array();
LargeXpos = new Array();
Smallspeed= new Array();
Largespeed= new Array();
ns=(document.layers)?1:0;
if (ns){
for (i = 0; i < SmallStars; i++)
{document.write("<LAYER NAME='sn"+i+"' LEFT=0 TOP=0 BGCOLOR='#FFFFF0' CLIP='0,0,1,1'></LAYER>")}
for (i = 0; i < LargeStars; i++)
{document.write("<LAYER NAME='ln"+i+"' LEFT=0 TOP=0 BGCOLOR='#FFFFFF' CLIP='0,0,2,2'></LAYER>")}
}
else{
document.write('<div style="position:absolute;top:0px;left:0px">');
document.write('<div style="position:relative">');
for (i = 0; i < SmallStars; i++)
{document.write('<div id="si" style="position:absolute;top:0;left:0;width:1px;height:1px;background:#fffff0;font-size:1px"></div>')}
document.write('</div>');
document.write('</div>');
document.write('<div style="position:absolute;top:0px;left:0px">');
document.write('<div style="position:relative">');
for (i = 0; i < LargeStars; i++)
{document.write('<div id="li" style="position:absolute;top:0;left:0;width:2px;height:2px;background:#ffffff;font-size:2px"></div>')}
document.write('</div>');
document.write('</div>');
}
WinHeight=(document.layers)?window.innerHeight:window.document.body.clientHeight;
WinWidth=(document.layers)?window.innerWidth:window.document.body.clientWidth;
//Inital placement!
for (i=0; i < SmallStars; i++)
{
SmallYpos = Math.round(Math.random()*WinHeight);
SmallXpos = Math.round(Math.random()*WinWidth);
Smallspeed= Math.random()*5+1;
}
for (i=0; i < LargeStars; i++)
{
LargeYpos = Math.round(Math.random()*WinHeight);
LargeXpos = Math.round(Math.random()*WinWidth);
Largespeed= Math.random()*10+5;
}
function fly(){
var WinHeight=(document.layers)?window.innerHeight:window.document.body.clientHeight;
var WinWidth=(document.layers)?
window.innerWidth:window.document.body.clientWidth;
var hscrll=(document.layers)?window.pageYOffset:document.body.scrollTop;
var wscrll=(document.layers)?window.pageXOffset:document.body.scrollLeft;
for (i=0; i < LargeStars; i++)
{
LargeXpos-=Largespeed;
if (LargeXpos < -10)
{
LargeXpos=WinWidth;
LargeYpos=Math.round(Math.random()*WinHeight);
Largespeed=Math.random()*10+5;
}
if (ns){
document.layers['ln'+i].left=LargeXpos;
document.layers['ln'+i].top=LargeYpos+hscrll;
}
else{
li.style.pixelLeft=LargeXpos;
li.style.pixelTop=LargeYpos+hscrll;
}
}
for (i=0; i < SmallStars; i++)
{
SmallXpos-=Smallspeed;
if (SmallXpos < -10)
{
SmallXpos=WinWidth;
SmallYpos=Math.round(Math.random()*WinHeight);
Smallspeed=Math.random()*5+1;
}
if (ns){
document.layers['sn'+i].left=SmallXpos;
document.layers['sn'+i].top=SmallYpos+hscrll;
}
else{
si.style.pixelLeft=SmallXpos;
si.style.pixelTop=SmallYpos+hscrll;
}
}
setTimeout('fly()',10);
}
//fly();
//-->
</script>
第二步：把“”加在<body>标记里
例如：<body >

显示全部楼层
把最后一行//fly();前面的//删除掉应该就行了吧？
//fly(); 改成 ==> fly(); |
