這篇文章主要為大家詳細(xì)介紹了javascript實(shí)現(xiàn)循環(huán)廣告條效果，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了javascript實(shí)現(xiàn)循環(huán)廣告條的具體代碼，供大家參考，具體內(nèi)容如下

html代碼:

<!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代碼：

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代碼：

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);//設(shè)置時(shí)間,本每隔多長(zhǎng)時(shí)間改變廣告條中的GIF
}

在循環(huán)廣告條中添加鏈接：修改js的代碼

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);//設(shè)置時(shí)間,本每隔多長(zhǎng)時(shí)間改變廣告條中的GIF
}
