图片横向滚动渐动渐停带左右控制JS，滚完一轮后在IE下会有少许错位

Question

网上下载的代码，自己对JS懂的不多，下面这段代码还请大佬们指点迷津gundong.jsvar sina = {

        if (document.getElementById) {
            return eval('document.getElementById("' + objName + '")')

问题是：加载网页图片横向每次按设定的宽度自动渐动渐停滚动，在IE下当滚动大概一轮（一圈）后，会有一次滚动的宽度多出设定的值，然后继续按设定的宽度滚动，接着发生同样的事会再一次滚动超出设定的宽度。但如果鼠标点击左右控制按钮，又能拉回到正轨上在FF下运行正常望技术大佬帮我看看

Answer 3

把这个样式注释掉
/*
.product_list ul {
    display: inline;
}
*/

Answer 4

偶的问题解决了，不知道LZ的问题解决没,我的解决方法加一句：<meta http-equiv="X-UA-Compatible" content="IE=7" />,网上找的产品滚动的解决办法，希望对LZ有所帮助: scrollpic.js各种浏览器兼容问题集锦:作为一个网页生产者，自然就避免不了与各种网页代码打交道，特别是那些制造各种特效的javascript脚本，有时遇到一个特别酷的效果，就有一种特别想扒下来研究的冲动。但对于一个非专业程序员而言，并不是每一个JS特效都能顺利参透，比如scrollpic.js这个有名的图片可控滚动插件，它比较常见的问题就有：IE6的编码兼容问题、IE8的滚动空白问题、FIREFOX/CHROME的styleFloat兼容问题等。最近因为忙于打造一个专题网页， 很自然的就用到了scrollpic.js插件，与许多人一样，在这个众多浏览器争霸天下的年代，我也遇到了不少有关兼容性的问题，所以下面就想简单分析一下以上问题的解决方法。    首页来讲一下IE6的编码兼容问题，虽然连微软自己都痛恨IE6的继续存在，但它在我国仍有半壁江山的占有率是目前不争的事实，为了考虑那些不知网页浏览器为何物的人们的感受，IE6的兼容问题还是得解决一下，如果你的网页运用了scrollpic.js，而且确信应用没有致命错误，但在IE6中就是不滚动，那么不用怀疑，一定是scrollpic.js的编码问题，用Dreamweaver之类的软件将其字符编码转换到与网页一致即可，例如调用网页的编码是UTF-8，那么scrollpic.js的字符编码也必须是UTF-8。    然后是IE8的问题，如果你没有在网页代码HEAD区声明“<meta http-equiv="X-UA-Compatible" content="IE=7" />”，那么就很可能遇到滚动一段时间后出现空白的问题，虽然在IE6中有时也会遇到类似的空白问题，但那多半都是容器或样式问题，并不需要像IE8这样作头部声明。    关于滚动出现空白的问题，在网上搜了一下，也有人建议找到scrollpic.js里面的“this.listDiv01.style.cssFloat=”left”;this.listDiv02.style.cssFloat=”left”;”语句，将其中两个cssFloat改为styleFloat，可以肯定的是，这样做非常奏效，但标准的写法却就是cssFloat，一旦改为styleFloat，那么像FIREFOX/CHROME等离所谓的WEB标准近一些的浏览器，就会无法识别，所以当你无法忽视FIREFOX/CHROME的存在时，建议不要做这样的尝试。    客观的讲，scrollpic.js的确是一个很好用的图文滚动插件，它不但可以左右控制无缝连续滚动，还可以兼容如此多的浏览器，真的是难能可贵。对于没有太多JS专业功底的网页生产者，这个插件用起来也不是很难，所以当你需要时就不妨大胆的用吧。早洩http://zaoxie.sg120.cn

scrollpic.js这个的代码和LZ的gongdong.js的内容是一样的
