var ajax=false;
try {
ajax = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {

var url = "/server/xml.php";

var show_check = document.getElementById("show_check");
var show_flag = document.getElementById("show_flag");

var ajax = ajax_init();
ajax.open("GET", url, true);

//var img = "";
ajax.onreadystatechange = function()
{
if (ajax.readyState == 4 && ajax.status == 200)
{
var ret = ajax.responseText;
var show_info = eval(ret);
show_check.innerHTML = show_info[0].no1; // bsd
show_flag.innerHTML = show_info[0].no2; // wuddy
//alert("responseXMLs value: " + info[0].firstChild.data);   
}
/*else
{
show.innerHTML = img;
}*/
}
ajax.send(null);
}

/*---------------json.php------*/
/* 这边如果写成 $ info = array(no1=>bsd, no2=>wuddy, no3=>xie); */
/* 同样要把html文件中必須 var show_info = eval([ + ret + ]); 都是返一个对象 */
$info = array(array(no1=>bsd, no2=>wuddy, no3=>xie));
$userinfo = json_encode($info);
echo $userinfo;
?>
