Rui 细节决定成败！

 

1创建XmlHttpRequest对象，读取，服务器端的reponse.xml文件内容

 

     <script type="text/javascript">
          var xmlHttp;
          function createXMLHttpRequest()
          {
              if(window.ActiveXObject)
              {
                  xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
              }
              else if(window.XMLHttpRequest)
            {
                xmlHttp = new XMLHttpRequest();
             }         }
         function startRequest()
        {        
            createXMLHttpRequest();
             xmlHttp.onreadystatechange = handleStateChange;
            xmlHttp.open("GET","AjaxSend.aspx?ID=1",true);
             xmlHttp.send(null);
         }
         function handleStateChange()
         {
             if(xmlHttp.readyState==4)
             {
                 if(xmlHttp.status==200)
                 {
                     alert("来自服务器的响应："+xmlHttp.responseText);
                    // document.getElementById ("Text1").innerText  =xmlHttp.responseText;
                 }
             }
        }

 
2 html代码

<input id="Button1" style="width: 85px" type="button" value="发送请求" onclick="startRequest();" />&nbsp;</div>

3 AjaxSend.aspx接受客户端的提交

 protected void Page_Load(object sender, EventArgs e)
    {
        string str = Request["ID"].ToString();
        if (str=="1")
        {
            Response .Write ("你好，欢迎您的来到!");
        }

    }
