Question

我有3页，涉及Ajax，step1.php，step2.php和step3.php：

step1.php

<head>

$.ajax({
    type: "POST",
    url: "step2.php",
    data: dataString,
    success: function(data) {

    } // end function
}); // end ajax  
</head>
<body>
<?php
// PHP codes
?>

step2.php

<head>
$.ajax({
    type: "POST",
    url: "step3.php",
    data: dataString,
    success: function(data) {

    } // end function
}); // end ajax  
</head>
<body>
<?php
$_SERVER['HTTP_X_REQUESTED_WITH']               = Isset($_SERVER['HTTP_X_REQUESTED_WITH'])      ? strip_tags($_SERVER['HTTP_X_REQUESTED_WITH']) : $_SERVER['HTTP_X_REQUESTED_WITH'] = Null;

    if(!$_SERVER['HTTP_X_REQUESTED_WITH'])
    {
         require_once '../Error/404.php';
    }
    else
    {

        $taken_time_start = time();

$num    = Isset($_POST['num'])      ? trim(intval(abs($_POST['num'])))      : $num      = Null;
$id_ism = Isset($_POST['id_ism'])   ? trim(intval(abs($_POST['id_ism'])))   : $id_ism   = Null;
$Start = Isset($_POST['Start'])   ? trim(intval(abs($_POST['Start'])))   : $Start   = Null;
$End = Isset($_POST['End'])   ? trim(intval(abs($_POST['End'])))   : $End   = Null;

$nums = $End - $Start;

if($nums < 2) {
//    echo 'please choose at least 3 s<br />';
$hideButton = 'false'; // hide show  button
} else {

$cSel = 'SELECT * FROM results WHERE s_ism = "'.$id_ism.'"';
//echo $aSel.'<br />';
$cReq = $connexion->query($cSel);
$cRes = $cReq->fetchAll();

if($cRes){
echo 'yes there is';
} else {
echo 'no';  
}
}
    } // end HTTP_REQUEST

等等，我的问题是：我可以使用jSON在step1.php处理中获得step2.php的结果吗？

谢谢大家
