每次刷新页面，都会显示不同的图片

在<body>与</body>之间插入以下代码
<SCRIPT language="JavaScript"><!--
today=new Date();
jran=today.getTime();
function rnd() {
ia=9301;
ic=49297;
im=233280;
jran = (jran*ia+ic) % im;
return jran/(im*1.0);
};
function rand(number) {
return Math.ceil(rnd()*number);
};
document.write("<left>");
for(i=1;i<=1;i++) {
myNum=(rand(5));
if(myNum == 1) document.write("<img src='http://eanling.net/share/bg/128.jpg'>");
if(myNum == 2) document.write("<img src='http://eanling.net/share/bg/133.jpg'>");
if(myNum == 3) document.write("<img src='http://eanling.net/share/bg/131.jpg'>");
if(myNum == 4) document.write("<img src='http://eanling.net/share/bg/129.jpg'>");
if(myNum == 5) document.write("<img src='http://eanling.net/share/bg/123.jpg'>");
else {
document.write();
}
};
document.write("</center>");
//-->
</SCRIPT>
说明：document.write("<left>");，这里的left为图片位置；myNum=(rand(5));5为图片数量；
if(myNum == 1) document.write("<img src='http://eanling.net/share/bg/128.jpg'>");
if(myNum == 2) document.write("<img src='http://eanling.net/share/bg/133.jpg'>");
if(myNum == 3) document.write("<img src='http://eanling.net/share/bg/131.jpg'>");
if(myNum == 4) document.write("<img src='http://eanling.net/share/bg/129.jpg'>");
if(myNum == 5) document.write("<img src='http://eanling.net/share/bg/123.jpg'>");
这里修改图片地址。 |
