    $json   = new JSON;
    $tradeno = isset($_GET['tradeno']) ? intval($_GET['tradeno']) : 0; 
    $pay_status = $GLOBALS['db']->getOne("select pay_status from ".$GLOBALS['ecs']->table('order_info')." where order_sn='$tradeno'");
    die($json->encode(Array('state'=>$pay_status,'value'=>'')));
}

<script type="text/javascript">
        $(document).ready(function () {
            setInterval("ajaxstatus()", 3000); 
        }); 
        function ajaxstatus() {
            if ($("#out_trade_no").val() != 0) { 
                $.ajax({ 
                    url: "控制器.php?act=方法名&tradeno=" + $("#out_trade_no").val(), 
                    type: "GET",

                    success: function (data) { 
                        //alert(data); 
                        if (data.state == 2) {  
                            window.location.href = "user.php?act=order_list"; //页面跳转 
                        }
