Answer 2

效果图：http://yuhai1958.w20.enkj.com  中间的产品展示
问题描述：在IE6/遨游/FireFox3.5中，均可正常实现图片一直轮换播放，但是在IE8 中只播放2次，请高人指点

Answer 3

感谢 foren_whb(丰云)，出现红叉，肯定是因为图片没显示

Answer 4

up
还有，http://yuhai1958.w20.enkj.com ,LZ我在IE6上看了,那个产品展示没有轮换滚动额

Answer 5

我之前也遇到过这问题，我直接把每张图片上面的alt加个参数，然后再ie8中可以正常跳了

没有人回答，看来大家都不喜欢看很长的代码，最终问题是解决了，谢谢各位的关注。通过在网页 head 中添加代码 <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />，能够一直循环播放了，不过我也没发现代码有什么问题， js 浏览器兼容性 问题，是个很头疼的问题，希望js 高手们，能够给予指点，不吝赐教。

Answer 9

为什么我添加了<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />
还是不能正常滚动呢？

Answer 10

我对比过ie和ff的就是因为this.listDiv01.scrollWidth的取值不同。ie是取32766的而ff是取实际多少图片的大小的。就算修改为实际的大小时，还有一个问题：如有九张图的。滚到第七张时，右边出现空白的。直至滚完第九张才会正常出现第一张图片。

Answer 11

问题解决：添加this.listDiv01.style.display="inline";this.listDiv02.style.display="inline";在js中就行了。

Answer 12

兼容性问题，我也查了一天啊，加上meta解决
