本文執行個體講述了JavaScript實現的多個圖片廣告交替顯示效果代碼。分享給大家供大家參考。具體如下：
這裡示範JavaScript讓多個Banner圖片廣告交替顯示的效果，如果你的站很牛，廣告位被佔滿了，你可以考慮讓多個圖片廣告輪番交替顯示，連結也跟著變，這樣是不是為你節省了寶貴的廣告位？思路是好，但不知道廣告效果是不是也一樣好，這就需要實驗了。
運行效果截圖如下：
線上示範地址如下：

具體代碼如下：
<html><head><title>圖片廣告交替顯示</title><script language="JavaScript" type="text/JavaScript"><!--var urlArray = new Array(3); var banArray = new Array(3); var counter = 1;var url = "http://www.jb51.net/"; //initial URLurlArray[0] = "http://www.jb51.net/";urlArray[1] = "http://www.baidu.com/";urlArray[2] = "http://www.163.com/";if(document.images) { for(i = 0; i < 3; i++) { banArray[i] = new Image(200, 60); banArray[i].src = "images/wall_s" + (i+1) + ".jpg"; }}function changeBanner() { if(counter > 2) counter = 0; document.banner.src = banArray[counter].src; //sets a new banner url = urlArray[counter]; counter++; }var timer = window.setInterval("changeBanner()", 3000);//--></script></head><body><a href="#" onClick="window.open(url,'BannerWin');"><img src="images/wall_s1.jpg" width=200 height=60 border=0 name="banner"></a></body></html>
