JS调用后台数据谷歌里没有数据显示？

Question

                 还是以前提出来了的一个问题：在IE里是好的，在谷歌里没有数据显示。 
           
        function callServer() 
        {
                  
           var url = "PageName.aspx?Id=" + escape("zx");
           
          xmlHttp.open("POST", url, true);
          xmlHttp.onreadystatechange = updatePage;
          xmlHttp.send(null);  
// xmlHttp.onreadystatechange=updatePage;
          // xmlHttp.open('POST',url,true);
            // xmlHttp.setRequestHeader('Content-Length',args.data.length);//post提交是要加这两行，好像上面这一行可以省略，
            // xmlHttp.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
            // xmlHttp.send("Id=" + escape("zx"));//post提交时参数要放在这里        }
         if (!xmlHttp && typeof XMLHttpRequest != 'undefined') 
        {
           xmlHttp = new XMLHttpRequest();
        }
        function updatePage() 
        {
               if (xmlHttp.readyState == 4) {
                                    var response = xmlHttp.responseText;  
                    // test1.innerHTML=response;              
                    //alert(response);
                   document.getElementById('test1').innerHTML=response;
                    
               }
        }这是显示的：
<div><span style="padding:0 2px 0 2px; font-size:10pt; font-weight:bolder;" id="test1" class="xiahuaxian"> </span></div>

             if(xmlHttp.readyState == 4 && xmlHttp.status == 200)
               {
                                    var response = xmlHttp.responseText;

        }

Answer 3

xmlHttp.open("POST", url, true);
xmlHttp.setRequestHeader("Connection", "close"); 
xmlHttp.onreadystatechange = updatePage;
xmlHttp.send(null);  

Answer 4

另外，
var url = "PageName.aspx?Id=" + escape("zx");
你是GET方法请求，无需POST
