AJAX 的應用 Part2---接收從server傳來的資料篇

Step 1:

以jsp來說,從server side要把想輸出的資料寫到一個檔案中, for example

result.jsp

<%     String xxxx= (String)request.getSession().getAttribute(oooo);     out.println(xxxx); %>

Step 2:
接著寫一段receive的javascript code把剛剛的檔案讀出來,for example

loadDoc:function(){
      var ajaxRequest;  // The variable that makes Ajax possible!
   
      try{
          // Opera 8.0+, Firefox, Safari
          ajaxRequest = new XMLHttpRequest();
      } catch (e){
          // Internet Explorer Browsers
          try{
              ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
          } catch (e) {
              try{
                  ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
              } catch (e){
                  // Something went wrong
                  alert("Your browser broke!");
                  return false;
              }
          }
      }
      ajaxRequest.onreadystatechange=function()
        {
        if (ajaxRequest.readyState==4 && ajaxRequest.status==200)
          {
          alert(ajaxRequest.responseText);
          }
        }
      ajaxRequest.open("GET", "result.jsp" , true);
      ajaxRequest.send();

即大功告成,至於傳request和接response的java script程式碼,要放在哪裡, 要根據自己的應用程式來決定,相信大家都沒問題的
