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="/UploadFiles/2021-04-02/script07.js">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 }以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
