//var img = "ajax处理php返回json数据例子_PHP教程";
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文件中必成 var show_info = eval([ + ret + ]); 都是返回一个对象 */
$info = array(array(no1=>bsd, no2=>wuddy, no3=>xie));
$userinfo = json_encode($info);
echo $userinfo;
