本文实例为大家分享了javascript实现循环广告条的具体代码，供大家参考，具体内容如下
html代码:
<!doctype html> <html> <head> <title>rotating banner</title> <script src="script07.js"></script> <link rel="stylesheet" href="script01.css" rel="external nofollow" > </head> <body> <div class="centered"> <img src="images/reading1.gif" id="adbanner" alt="ad banner"> </div> </body> </html>
css代码：
body {
background-color: white;
color: black;
font-size: 20px;
font-family: "lucida grande", verdana,arial, helvetica, sans-serif;
}
h1, th {
font-family: georgia, "times new roman",times, serif;
}
h1 {
font-size: 28px;
}
table {
border-collapse: collapse;
}
th, td {
padding: 10px;
border: 2px #666 solid;
text-align: center;
width: 20%;
}
#free, .pickedbg {
background-color: #f66;
}
.winningbg {
background-image:url(images/redflash.gif);
}
js代码：
window.onload = rotate;
var thisad = 0;
function rotate() {
var adimages = new array("images/ reading1.gif","images/reading2. gif","images/reading3.gif");
thisad++;
if (thisad == adimages.length) {
thisad = 0;
}
document.getelementbyid("adbanner").src = adimages[thisad];
settimeout(rotate, 3 * 1000);//设置时间,本每隔多长时间改变广告条中的gif
}
在循环广告条中添加链接：修改js的代码
window.onload = initbannerlink;
var thisad = 0;
function initbannerlink() {
if (document.getelementbyid("adbanner").parentnode.tagname == "a") {
document.getelementbyid("adbanner").parentnode.onclick = newlocation;
}
rotate();
}
function newlocation() {
var adurl = new array("negrino.com","sun.com","microsoft.com");
document.location.href = "http://www." + adurl[thisad];
return false;
}
function rotate() {
var adimages = new array("images/ reading1.gif","images/reading2. gif","images/reading3.gif");
thisad++;
if (thisad == adimages.length) {
thisad = 0;
}
document.getelementbyid("adbanner").src = adimages[thisad];
settimeout(rotate, 3 * 1000);//设置时间,本每隔多长时间改变广告条中的gif
}
