我用了this.clientWidth就出错了 你的图片规格是随机的? 那只有用js了 var img = new image();img.src = "xxx/xxx";img.onload = function () {计算设置margin什么的让他居中}水平居中直接{ display:block;margin: 0 auto;}就好 垂直就用上面的JS计算吧 再试试<!DOCTYPE HTML><html><head><style type="text/css">html,body{width:100%;height:100%}#banner {position:relative; height:100%; overflow:hidden; }#banner ul {position:absolute;list-style-type:none;filter: Alpha(Opacity=80);opacity:0.8; z-index:1002; margin:0; padding:0; bottom:10%; left:50%;}#banner ul li { padding:0px 8px;float:left;display:block;color:#FFF;background:#6f4f67;cursor:pointer}#banner ul li.on { background:#900} #banner_list img {border:0px; width:100%;}#banner_list a{position:absolute;} </style> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script><script type="text/javascript"> var t = n = 0, count; $(document).ready(function(){ count=$("#banner_list a").length; var bw=$('body').width(),bh=$('body').height(); $('#banner_list img').load(function(){ resizeImg(this); var p=$(this).parent(); if(p.index())p.hide(); }); $('#banner_list img').each(function(i){ resizeImg(this); if(this.offsetWidth && i)$(this).parent().hide(); }); function resizeImg(img){ if(!img.offsetWidth ) return; var img=$(img),w=img.width(),h=img.height(); if(bh<h){ w=parseInt(bh/h*w); h=bh; }else if(bw<w){ h=parseInt(bw/w*h); w=bw; }else{ if(w>h){ h=parseInt(bw/w*h); w=bw; }else{ w=parseInt(bh/h*w); h=bh; } } img.css({ width:w, height:h }); img.parent().css({ left: (bw-w)>>1, top: (bh-h)>>1 }); } $("#banner li").click(function() { var i = $(this).text()-1; n = i; if (i >= count) return; $("#banner_list a").filter(":visible").fadeOut(500).parent().children().eq(i).fadeIn(1000); //document.getElementById("banner").style.background=""; $(this).toggleClass("on"); $(this).siblings().removeAttr("class"); }); //t = setInterval("showAuto()", 3000); // $("#banner").hover(function(){clearInterval(t)}, function(){t = setInterval("showAuto()", 4000);}); }) // function showAuto()// {// n = n >=(count - 1) ?

感谢wbb123yu的提示,我在img加了个
min-height: expression(document.documentElement.clientHeight + "px");现在的效果是不管网页多大多宽,图片都是等比例放大或者缩小的全屏
剩下最后一步了,如何让图片永远水平居中和垂直居中fzfei2 你的代码还是不行哦,没有切换效果,图片也没有居中
我测试ie8, the world,都不行,不知道哪里问题
你的图片规格是随机的? 那只有用js了 var img = new image();
img.src = "xxx/xxx";
img.onload = function () {计算设置margin什么的让他居中}水平居中直接{ display:block;margin: 0 auto;}就好 垂直就用上面的JS计算吧

感谢fzfei2的调试,还是不可以,我重新贴一遍我改过的代码,全屏图片切换已经可以实现了,就是怎么设置图片高度宽度永远居中问题!<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 4.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
