Javascript AJAX功能在IE中不起作用?

Sam*_*152 2 javascript internet-explorer xmlhttprequest

我有这个代码:

function render_message(id)
{
var xmlHttp;
  xmlHttp=new XMLHttpRequest();  
  xmlHttp.onreadystatechange=function()
    {
    if(xmlHttp.readyState==4)
      {
        document.getElementById('message').innerHTML=xmlHttp.responseText;
        document.getElementById('message').style.display='';
        }
    }
    var url="include/javascript/message.php";
    url=url+"?q="+id;
  xmlHttp.open("GET",url,true);
  xmlHttp.send(null);
}

由于某种原因,它在IE中不起作用,并且在此行上报告了错误"document.getElementById('message').innerHTML = xmlHttp.responseText;" 带有"未知运行时错误".

有人可以帮忙吗?

编辑:添加到div的代码是有效代码等.
