<SCRIPT LANGUAGE="JavaScript">
<!--
function ajaxByJyking(){
var xmlhttp_request = "";
try{
if( window.ActiveXObject ){
for( var i = 5; i; i-- ){
try{
if( i == 2 ){

else{
xmlhttp_request = new ActiveXObject( "Msxml2.XMLHTTP." + i + ".0" );
xmlhttp_request.setRequestHeader("Content-Type","text/xml");
xmlhttp_request.setRequestHeader("Charset","gb2312"); }
break;}
catch(e){
xmlhttp_request = false; } } }
else if( window.XMLHttpRequest )
{ xmlhttp_request = new XMLHttpRequest();
if (xmlhttp_request.overrideMimeType)
{ xmlhttp_request.override.MimeType('text/xml'); } } }
catch(e){ xmlhttp_request = false; }
xmlhttp_request.open('GET', 'http://www.jb51.net', true);
xmlhttp_request.send(null);
xmlhttp_request.onreadystatechange = function(){
if (xmlhttp_request.readyState == 4) {
// 收到完整的伺服器響應
