把xmlReportData.async = "false"; 改成xmlReportData.async = "true";就是异步

Index.html文件:
<script language="javascript">
var xmlDoc;
function initialize()
{
  if(window.ActiveXObject)
    {
      xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
      xmlDoc.onreadystatechange=function()
      {
        if(xmlDoc.readyState==4)
        {
          handleXmlDoc();
        }
      }
      xmlDoc.load("data.xml");
    }
  else if(document.implementation&&document.implementation.createDocument)
  {
    xmlDoc=document.implementation.createDocument('','',null);
    xmlDoc.onload=handleXmlDoc;
    xmlDoc.load("data.xml");
  }
}
function handleXmlDoc()
{
  var root=xmlDoc.documentElement;
  var info=root.getElementsByTagName("info")[0];
  alert(info.getAttribute("type"));
  for(var i=0; i<info.childNodes.length; i++)
  {
    alert(info.childNodes[i].firstChild.nodeValue);
  }
}
window.onload=initialize;
</script>xml文件:
<?xml version="1.0" encoding="GB2312"?>
<root>
    <info type="student">
      <name>Hello</name>
      <sex>Female</sex>
    </info>
</root>

Answer 5

谢谢，不过还有些地方看不懂能不能给下注释。我要在HTML中用JavaScript代码异步获取，XML文件中一个节点的值比如<?xml version="1.0" encoding="GB2312"?>
<configuration>
   <appSettings>
<add key="123" value="456"/>
   </appSettings>
</configuration>我要在页面中异步获取<add>节点中key属性和value属性的值!也就是得到123和456
