如何实现这个功能?
在网页中插入一个image,希望在每次访问或者刷新页面的时候,这个image能够显示不同的图片?
------解决方案--------------------不知道这个对楼主有没有帮助:
《随机显示图片脚本》
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> ");
//-->
</SCRIPT>
