随机显示图片脚本

下面为效果显示区!

脚本说明:

把如下代码加入<body>区域中

<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("<CENTER>");

for(i=1;i<=1;i++) {

myNum=(rand(10)); //改成你要随机显示的图片数；

if(myNum == 1) document.write("<img src='back.jpg'>");

if(myNum == 2) document.write("<img src='j2.gif'>"); //图片路径，可用http://

if(myNum == 3) document.write("<img src='email.gif'>");

if(myNum == 4) document.write("<img src='arrow.gif'>");

if(myNum == 5) document.write("<img src='j2.gif'>");

if(myNum == 6) document.write("<img src='email.gif'>");

if(myNum == 7) document.write("<img src='arrow.gif'>");

if(myNum == 8) document.write("<img src='j2.gif'>");

if(myNum == 9) document.write("<img src='back.jpg'>");

if(myNum == 10) document.write("<img src='email.gif'>");

else {

document.write();

}

};

document.write("</CENTER>");
