#box{ height:450px; margin:0 auto; border:red solid 2px; overflow:hidden; position:relative;}
#box img{ position:absolute; left:0; display:block; border-left:#CCCCCC solid 1px;}
JS
window.onload=function(){
var box=document.getElementById('box');
var imgs=box.getElementsByTagName('img');
var imgwidth=imgs[0].offsetwidth;
var exposewidth=160;
var boxwidth=imgwidth+(imgs.length-1)*exposewidth;
box.style.width=boxwidth+'px';
for(var i=1,len=imgs.length;i<len;i++){
imgs[i].style.left=imgwidth+exposewidth*(i-1)+'px';
}
};
总宽度没变化 图片也没法全出来
很小的错误
var imgwidth = imgs[0].offsetWidth;
offsetWidth你写错了而已。
图片没有刷出来 只能说明路径错误。html文件 是在所有文件的外部吗？
