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

coolboy347 2011-10-08 10:36:38
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.js
[code=JScript]
var sina = {
$: function(objName) {
if (document.getElementById) {
return eval('document.getElementById("' + objName + '")')
} else {
return eval('document.all.' + objName)
}
},
isIE: navigator.appVersion.indexOf("MSIE") != -1 ? true: false,
addEvent: function(l, i, I) {
if (l.attachEvent) {
l.attachEvent("on" + i, I)
} else {
l.addEventListener(i, I, false)
}
},
delEvent: function(l, i, I) {
if (l.detachEvent) {
l.detachEvent("on" + i, I)
} else {
l.removeEventListener(i, I, false)
}
},
readCookie: function(O) {
var o = "",
l = O + "=";
if (document.cookie.length > 0) {
var i = document.cookie.indexOf(l);
if (i != -1) {
i += l.length;
var I = document.cookie.indexOf(";", i);
if (I == -1) I = document.cookie.length;
o = unescape(document.cookie.substring(i, I))
}
};
return o
},
writeCookie: function(i, l, o, c) {
var O = "",
I = "";
if (o != null) {
O = new Date((new Date).getTime() + o * 3600000);
O = "; expires=" + O.toGMTString()
};
if (c != null) {
I = ";domain=" + c
};
document.cookie = i + "=" + escape(l) + O + I
},
readStyle: function(I, l) {
if (I.style[l]) {
return I.style[l]
} else if (I.currentStyle) {
return I.currentStyle[l]
} else if (document.defaultView && document.defaultView.getComputedStyle) {
var i = document.defaultView.getComputedStyle(I, null);
return i.getPropertyValue(l)

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

.product_list {

overflow: hidden;
margin-right: auto;
margin-left: auto;
padding-top: 10px;
padding-bottom: 10px;

margin-right: 5px;
margin-left: 5px;
text-align: center;
line-height: 30px;
margin-bottom: 20px;
}


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
