如何利用Ajax傳遞Xml文檔教程詳解

用戶端

<script language="javascript"> //產生XML檔案  function GetAllFormData()  {      var strXML = "<Client>\r\n<FormData>\r\n";      strXML += "<UserName>bccu</UserName>"     strXML += "<Age>25</Age>";      strXML += "</FormData>\r\n</Client>"     return strXML;  }  ///向服務器發送XML文檔  function Send(Str,URL)   {      var Http = new ActiveXObject("Microsoft.XMLHTTP")      Http.open("POST",URL,false)      Http.send(Str)      return Http.responseText;  }  ///獲得XML中指定的節的值  function GetXMLNodeValue(strXML,nodeName)  {      var Dom = new ActiveXObject("Microsoft.XMLDOM")      Dom.async=false       Dom.loadXML(strXML)      if(Dom.parseError.errorCode != 0)       {          delete(Dom)          return(false)      }      else      {          var node = Dom.documentElement.selectSingleNode("//"+nodeName);          if(node)              nodeValue = node.text;          delete(Dom)          return(nodeValue);      }  }   function Test()   {      var tmp       = Send(GetAllFormData(),"./test.aspx");      var name      = GetXMLNodeValue(tmp,"UserName");      var password  = GetXMLNodeValue(tmp,"Age");   }  </script>

伺服器端（test.cs）

System.IO.Stream stream = Request.InputStream System.Xml.XmlDocument doc = new XmlDocument();  try  {    doc.Load(stream); //載入發送過來的Xml文檔 }  catch  {    byte[] buffer = new byte[stream.Length];    stream.Read(buffer,0,buffer.Length);    string strXML = System.Text.UnicodeEncoding.Default.GetString(buffer,0,buffer.Length);    doc.LoadXml(strXML);  }  //將doc處理後輸出以便返回到用戶端(此處省略) response.write("")
