我有一个 JQGRid，它显示带有双击事件的预订，如下所示:
ondblClickRow: function(rowid)
{
rowData = $("#bookings").getRowData(rowid);
var brData = rowData['bookref'];
getGridRow(brData);
},
这将传递给 getGridRow 函数:
function getGridRow(brData) {
//$.post('bookings-dialog.php', { 'rowdata': brData } );
// $("#cp-bookings-dialog").load('bookings-dialog.php').dialog({ show: "slide", hide: 'slide', height: 625, width: 733, title: 'Booking Reference: - '+ brData});
$.ajax({
url: 'bookings-dialog.php',
type:'POST',
data: {'rowdata' : brData },
dataType: 'JSON', //this is what we expect our returned data as
error: function(){
alert("It failed");
$('#cp-div-error').html('');
$('#cp-div-error').append('<p>There was an error inserting the data, please try again later.</p>');
$('#cp-div-error').dialog('open');
},
success: function(data){
alert("IT WORKED!");
//empty our dialog so we don't end up with duplicate content
$('.cp-booking-info').empty();
//we have told the browser to expect JSON back, no need to do any parsing
//the date
$('#cp-bookings-dialog').append('<p class="pno-margin">Booking Date: '+data.bookref+'</p>');
//now let's manipulate our dialog and open it.
$("#cp-bookings-dialog").dialog({
show: { effect: 'drop', direction: "up" },
hide: 'slide',
height: 625,
width: 733,
title: 'Booking Reference: - '+ brData
});
}
});
这是 bookings-dialog.php:

$booking_ref = BookingDocket::get_bookref();
return json_encode(array('bookref' => $booking_ref,
)
);
$stmt->closeCursor();
}
catch (PDOException $pe) {
die("Error: " .$pe->getMessage(). " Query: ".$stmt->queryString);
}
$dbh = null;
?>

基本上应该发生的是，预订引用 (brData) 应该传递给 booking-dialog.php，并在查询中使用传递的引用数据从预订数据库中选择所有预订。
我目前遇到的问题是，目前我在预订 list 上获得的值(value)是“未定义的”。从服务器发回的 header 有问题，还是 JSON 对象的结构有问题？
如果有人能帮我解决这个问题，我将不胜感激，我花了很长时间试图让它发挥作用，而且它看起来很简单。
最佳答案
bookings-dialog.php 不应该显示 HTML 元素，它应该返回 JSON 编码的字符串。
添加你的结果，另一个错误，然后你可以处理来自 jQuery 的错误
例如:
<?php
require_once('deployment.php');
require_once('bootstrp/all.inc.php');;
require_once('models/sql.php');
require_once('models/bookingdocket.php');
$pdo = new SQL();
$dbh = $pdo->connect(Database::$serverIP, Database::$serverPort, Database::$dbName, Database::$user, Database::$pass);
try {
$rowdata = $_POST['rowdata'];
$query = ("SELECT * FROM tblbookings WHERE bookref = :bookref");
$stmt = $dbh->prepare($query);
$stmt->execute(array(':bookref' => $_POST['rowdata']));
$row = $stmt->fetch(PDO::FETCH_BOTH);
BookingDocket::set_bookref($row['bookref']);
echo json_encode( array('bookref' => $row['bookref'], 'date' => $row['bookingdate'], 'error' => 'no') );
$stmt->closeCursor();
}
catch (PDOException $pe) {
die(json_encode(array("error" => "Error: " .$pe->getMessage(). " Query: ".$stmt->queryString)));
}
$dbh = null;
?>
同样在您的 getGridRow 中检查错误字段:
success: function(data){
if(typeof console != "undefined"){ console.log(data); } // this will prompt data in console
if(data.error == 'no'){
alert("IT WORKED!");
$('.cp-booking-info').empty();
$('#cp-bookings-dialog').append('<p class="pno-margin">Booking Date: '+data.date+'</p>');
$("#cp-bookings-dialog").dialog({
show: { effect: 'drop', direction: "up" },
hide: 'slide',
height: 625,
width: 733,
title: 'Booking Reference: - '+ data.bookref
});
} else {
alert(data.error);
}
}
