关于手写 Ajax

  function createHttpRequest(){
   var httprequest=false;
   if (window.XMLHttpRequest)
   { // if Mozilla, Safari etc
     httprequest=new XMLHttpRequest();
     if (httprequest.overrideMimeType)
       httprequest.overrideMimeType('text/xml');
    }
    else if (window.ActiveXObject)
    { // if IE
      try {
        httprequest=new ActiveXObject("Msxml2.XMLHTTP");
      }
      catch (e){
        try{
           httprequest=new ActiveXObject("Microsoft.XMLHTTP");
        }
        catch (e){}
      }
    }
    return httprequest;
 }
 
 
function createXml(str){
if(document.all){
 var xmlDom=new ActiveXObject("Microsoft.XMLDOM")
 xmlDom.loadXML(str)
 return xmlDom
}
else
 return new DOMParser().parseFromString(str, "text/xml")
}

 

 

  function showSchedule(sid,f){
   var url = "../schedule.do?operate=toFindById";
   var postStr = "uid=" + encodeURI(sid);
       
    //IE浏览器关于频繁传送数据初始化的问题
   httpRequest.open("POST", url, true);
   httpRequest.onreadystatechange = function(){
    if(httpRequest.readyState == 4)
     if(httpRequest.status == 200){
      var xml = createXml(httpRequest.responseText);
      var item = xml.getElementsByTagName("Schedule")[0];

    Document doc = DocumentHelper.createDocument();

================================

request.setContentType("text/xml");

httpRequest.resoponseXML;

===========================
利用函数格式化 POST 请求参数

 function addParam(paramObj, paramName, paramValue){
  if(paramObj.length > 0)
   paramObj += "&";
  return paramObj + encodeURIComponent(paramName)
   + "=" + encodeURIComponent(paramValue);
 }


=============================================
javascript 里面的遍历

for (pop in windowxxxx){
    .....
}
