静

使用innerHTML属性创建动态内容
完整代码：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title>Using responseText with innerHTML</title>
    <script language="JavaScript" type="text/javascript">
            //创建 XmlHttpRequest 对象
            function createXmlHttpRequestObject() {
                if (window.XMLHttpRequest) {
                    return new XMLHttpRequest(); //Not IE
                } 
                else if(window.ActiveXObject) {
                    return new ActiveXObject("Microsoft.XMLHTTP"); //IE
                } 
                else {
                    alert("Your browser doesn't support the XmlHttpRequest object.  Better upgrade to Firefox.");
                }
            }            

            var receiveReq = createXmlHttpRequestObject();    

            function GetinnerHTML() {
                if (receiveReq.readyState == 4 || receiveReq.readyState == 0) {
                    //建立对服务器的调用，call to SayHello.html(555)
                    receiveReq.open("GET", 'innerHTML.xml', true);
                    //每个改变时都会触发这个事件处理器，通常会调用一0个javascript函数！(666) Set the function that will be called when the XmlHttpRequest objects state changes.
                    receiveReq.onreadystatechange = CallBack; 
                    //向服务器发送请求
                    receiveReq.send(null);
                }            
            }
            //CallBack()
            function CallBack() {
                if (receiveReq.readyState == 4) {
                    document.getElementById('span_result').innerHTML = receiveReq.responseText;
                }
            }
            </script>
</head>
<body>
<a href="javascript:GetinnerHTML();">GetInnerHTML</a><br />
<!--<span id="span_result"></span>-->
<div id="span_result"></div>
</body>
</html>

属性responseText将响应提供为一个串，所以innerHTML.xml可以是一个“HelloWorld”字符串，也可以是一个表格：
<table border="1">
  <tbody>
    <tr>
      <th>Activity Name</th>
      <th>Location</th>
      <th>Time</th>
    </tr>
    <tr>
      <td>Waterskiing</td>
      <td>Dock #1</td>
      <td>9:00 AM</td>
    </tr>
    <tr>
      <td>Volleyball</td>
      <td>East Court</td>
      <td>2:00 PM</td>
    </tr>
    <tr>
      <td>Hiking</td>
      <td>Trail 3</td>
      <td>3:30 PM</td>
    </tr>
  </tbody>
</table>
