浏览器兼容问题~

页面IE浏览器访问可以正常显示表格内数据，firefox也可以显示表格但页面有部分错位，谷歌浏览器Chrome完全不能显示表格内容，请高手指点一下~~代码如下：
// JavaScript Document
var xmlDoc;
function loadComputerXML()
{//document.getElementById ('List1').innerHTML ='数据导入中';
if (window.ActiveXObject)
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
//xmlDoc.load("http://trial.ppclass.net/management/get_service_data/");
xmlDoc.load("/management/get_service_data");
getmessage();
}
else if (document.implementation && document.implementation.createDocument)
{
xmlDoc=document.implementation.createDocument("","",null);
xmlDoc.load("/management/get_service_data");
xmlDoc.onload=getmessage;
}
else
{
alert('Your browser cannot handle this script');
}
// if(window.XMLHttpRequest){ 
//              xmlDoc = new XMLHttpRequest(); 
//          } else if(window.ActiveXObject){ 
//              xmlDoc = new ActiveXObject("Microsoft.XMLHTTP"); 
//          } else { 
//              return; 
//          } 
//          xmlDoc.onreadystatechange = function(){ 
//            if(xmlDoc.readyState == 4){ 
//               //updateObj("xmlObj", xmlObj.responseXML.getElementsByTagName("Class")[0].childNodes[1].text); 
//               getmessage();
//             } 
//            } 
//            //xmlDoc.open ("GET", "http://trial.ppclass.net/management/get_service_data/", true); 
//            xmlDoc.open ("GET", "data/service_data.xm ", true); 
//            xmlDoc.send ("")
}
function getmessage(){
  //var results = xmlDoc.responseXML;
  dataArray = xmlDoc.getElementsByTagName('Channel'); 
      var dataArrayLen = dataArray.length; 
  //alert(dataArrayLen);
