在线客服的函数，在谷歌浏览器里出不来，而在360和IE里都能出来，为什么？很迷茫。。。
我在body里面调用了在线客服的函数，可是在谷歌浏览器里出不来，而在360和IE里都能出来，为什么？
代码是：<script event="onload" for="window" language="javascript">
init_Ad_Right();//载入页面后，调用函数init_Ad_Right()
</script>
<script language="javascript">
<!--
function init_Ad_Right()
{
document.all.AdRightLayer.style.posTop = -300; //设置onLoad事件激发以后，广告层相对于固定后的y方向位置
document.all.AdRightLayer.style.visibility = 'visible'; //设置层为可见
MoveRightLayer('AdRightLayer'); //调用函数MoveRightLayer()
}
function MoveRightLayer(layerName)
{
var x = 20; //浮动广告层固定于浏览器的x方向位置
var y = 50;//浮动广告层固定于浏览器的y方向位置
var diff = (document.documentElement.scrollTop + y - document.all.AdRightLayer.style.posTop)*.90;
var y = document.documentElement.scrollTop + y - diff;
eval("document.all." + layerName + ".style.posTop = y");
eval("document.all." + layerName + ".style.posright = x");//移动广告层
setTimeout("MoveRightLayer('AdRightLayer');", 0);//设置20毫秒后再调用函数MoveRightLayer()
}
//-->
</script>
<div id="AdRightLayer" style='position: absolute; width: 119px; height: 200px; z-index: 20; visibility: hidden; right: 12px; top: 600px'>

谷歌浏览器报错是：

Uncaught TypeError: Cannot call method 'getElementsByTagName' of null
[解决办法]
错误应该是这个:
Uncaught TypeError: Cannot call method 'getElementsByTagName' of null
------解决方案--------------------
在Chrome中打开Developer tool(按F12). 应该能看到错误。
[解决办法]
可能性有多种。
HTML是从上到下加载的，如果你的js执行在HTML加载之前是获取不到页面元素的，所以尽量将你的js和引用的js在最后面加载
Cannot call method 'getElementsByTagName' of null 看上去应该是getElementsByTagName在chrome里不能用，不妨用jquery获取试试。是不存在兼容性的。
还有，看下你的html body head这些标签是否闭合
