 請教-網頁輪顯圖片怎麼做的？
大家看看http://hgxn.vicp.net/index.asp
她上方的圖片美刷新一次換一個，怎麼做的？
謝謝 |
隨機顯示？
[html]
<script language="javascript">
var how_many_ads = 4;
var now = new Date()
var sec = now.getSeconds()
var ad = sec % how_many_ads;
ad +=1;
if (ad==1) {
url="http://www.lemongtree.net/bbs/";
alt="www.lemongtree.net";
banner="http://www.lemongtree.net/logo.gif";
}
if (ad==2) {
url="http://showtop.net";
alt="ShowTop.Net";
banner="http://deepsky.y365.com/images/banner.gif";
}
if (ad==3) {
url="http://www.gamvan.com/";
alt="http://www.gamvan.com/link/imgs/gv.gif";
banner="http://www.gamvan.com/link/imgs/gv.gif";
}
if (ad==4) {
url="http://www.blueidea.com/";
alt="http://www.blueidea.com/";
banner="http://www.blueidea.com/img/common/logo.gif";
}
if (ad==5) {
url="";
alt="";
banner="";
}
document.write('<a href=\"' + url + '\" target=\"_blank\">');
document.write('<img src=\"' + banner + '\" width=88 height=31 ')
document.write('alt=\"' + alt + '\" border=0></a>');
</script>
[/html]
可以另存為JS文件調用,具體調用方法見這裡:

請教一下，我用隨機數做得為什麼不對？
[html]
<script language="javascript">
function change()
{
i=Math.floor(Math.random()*16)
oImg.src="icon/icon"+i+".gif"
}
onload=change()
}
</script>
<img src=icon/icon0.gif id="oImg">
[/html] |
從別人的網站扣出來的
上次是誰問看到這個網站的效果
要代碼
我就給摳出來了
