Ⅰ JS如何實現圖片滑動
<script language="javascript" type="兄凱text/javascript">
//圖片滾動展示 Start
var counts = 4;
//大圖//
img1 = new Image();
img1.src = 'images/1.jpg';
img2 = new Image();
img2.src = 'images/2.jpg';
img3 = new Image();
img3.src = 'images/3.jpg';
img4 = new Image();
img4.src = 'images/4.jpg';
var smallImg = new Array();
//小圖
smallImg[0] = 'images/index_adb1.gif';
smallImg[1] = 'images/index_adb2.gif';
smallImg[2] = 'images/index_adb3.gif';
smallImg[3] = 'images/index_adb4.gif';
//鏈接地址
url1 = new Image();
url1.src = ' http://www..com';
url2 = new Image();
url2.src = ' http://www.qzxtg.com';
url3 = new Image();
url3.src = ' http://www.soso.com';
url4=new Image();
url4.src=' http://www.sina.com.cn'
//派老alt值
alt1 = new Image();
alt1.alt = '';
alt2 = new Image();
alt2.alt = '';
alt3 = new Image();
alt3.alt = ' ';
alt4 = new Image();
alt4.alt='';
