来自MySQL的JSON提要有效,但不超过x条记录

Question

我正在尝试使用FullCalendar来处理我的MySQL数据库.当我将查询限制为25条记录时,这种方法有效.当我将我的sql查询更改为限制时,假设35条记录,Fullcalendar将不会添加任何事件并且基本上保持加载.

我用firebug检查了JSON响应是什么,并且在两次完成时都是如此.

起初我以为问题是SQL查询.DB长度超过5000条,但JSON响应的加载时间不到200毫秒.

我正在使用demo json.html文件进行测试.将在这里发布功能:

<script type='text/javascript'>
$(document).ready(function() {
    $('#calendar').fullCalendar({
        editable: true,
        events: "json-events.php",
        eventDrop: function(event, delta) {
            alert(event.title + ' was moved ' + delta + ' days\n' +
                '(should probably update your database)');
        },

        loading: function(bool) {
            if (bool) $('#loading').show();
            else $('#loading').hide();
        }
    });
});
</script>

这是我的json-events.php

<?php
    $conn = mysql_connect("") or die ("Unable to connect to MySQL server.");

    $Exec = mysql_query("select Brand, date_in from planning ORDER BY date_in Desc Limit 35",$conn) or die(mysql_error());
    mysql_close();

    $events = array();

    while($row = mysql_fetch_assoc($Exec)) {
        $eventArray['title'] = $row['Brand'];
        $eventArray['start'] = $row['date_in'];
        $eventsArray['allDay'] = "";
        $events[] = $eventArray;
    }

    header('Content-type: application/json');

    echo json_encode($events);
?>

这是JSON响应:

[{"title":"Volkswagen Passat","start":"2011-04-28"},{"title":"Seat Alhambra","start":"2011-04-28"},{"title ":"Ford Focus","start":"2011-04-20"},{"title":"BMW 5-Serie","start":"2011-04-20"},{"title": "Ford Mondeo","start":"2011-04-20"},{"title":"Volkswagen Caddy","start":"2011-04-20"},{"title":"Opel Zafira" ,"start":"2011-04-18"},{"title":"Mazda 3","start":"2011-04-14"},{"title":"Opel Vectra","start" :"2011-04-14"},{"title":"Peugeot 207","start":"2011-04-14"},{"title":"Volkswagen Golf","start":"2011- 04-14"},{"title":"Volvo V90","start":"2011-04-14"},{"title":"Volvo V50","start":"2011-04-14" },{"title":"Volkswagen Polo","start":"2011-04-14"},{"title":"Volkswagen Golf","start":"2011-04-14"},{"标题":"福特蒙迪欧","开始":"2011-04-14"},{"标题":"奥迪","开始":"2011-04-14"},{"标题":"宝马525i","start":"2011-04-14"},{"title":"Renault Laguna","start":"2011-04-14"},{"title":"Opel Astra","开始":"2011-04-14"},{"title":"Seat Alambhra","start":"2011-04-14"},{"title":"Peugeot 307","start":" 2011-04-13" },{"title":"Hyundai Atos","start":"2011-04-13"},{"title":"Citroen Xsara Picasso","start":"2011-04-13"},{ "title":"Opel Astra","start":"2011-04-13"},{"title":"Volkswagen Golf","start":"2011-04-13"},{"title": "Peugeot 307","start":"2011-04-13"},{"title":"Volkswagen Passat","start":"2011-04-13"},{"title":null,"start ":"2011-04-13"},{"title":"雪铁龙C1","开始":"2011-04-13"},{"标题":"丰田凯美瑞","开始":"2011 -04-13"},{"title":"Toyota Aygo","start":"2011-04-13"},{"title":"Nissan Qashqai","start":"2011-04-13 "},{"title":"BMW 3 touring","start":"2011-04-12"},{"title":"Toyota Prius","start":"2011-04-12"}]

我尝试了所有可以想到的东西,我花了5个小时试图完成这项工作.

有没有人知道如何使这项工作？

Answer 1

看起来错误在您的数据库中.

在您的JSON Feed中,您有一个条目

{"title":null,"start":"2011-04-13"}

那个null可能就是让你失望的原因.
