JSONstore沒有正確返回數據

Question

我已經有一段時間了現在這個問題，但我一直在縮小這個問題，我認爲我現在有主要問題。雖然我的JSONstore正確地調用了PHP，並且螢火蟲確實從數據庫中提供了正確的數據，但它不會顯示在我的網格中。

我有一個網格只有2列日期和日誌條目。當我取出日誌條目時，網格會顯示日期，並且當我剛剛使用日誌中的靜態數據創建數組時，它也會在網格中顯示正常。我認爲我的JSONstore只是不正確地從mysql表中解析數據。

我的代碼是：

var logStore = new Ext.data.JsonStore({ 
    autoLoad: true, 
    url: 'inc/interface/config.php?list=messages', 
    root: 'dates', 
    idProperty: 'ID', 
    fields: ['ID', 'ReceivedAt', 'Message'], 
    listeners: { 
       loadexception: function() { 
        console.log('load failed -- arguments: %o', arguments); 
       } 
     } 
}); 

    var logGrid = new Ext.grid.GridPanel({ 
     region: 'center', 
     store: logStore, 
     colModel: new Ext.grid.ColumnModel({ 
      columns: [{ 
       id: 'received', 
       header: 'Received', 
       dataIndex: 'ReceivedAt', 
       width: 250 
      },{ 
       id: 'message', 
       header: 'Logs', 
       dataIndex: 'Message', 
       width: 750 
      }] 
     }) 
    }); 

它拉動日誌條目的一個例子是：

| Apr 9 00:00:02 dh1 dhcpd: Added new forward map from nfxxxxich-PC.wifi-uhs.osu to 10.xxx.xx.248 | 
| Apr 9 00:00:02 dh1 dhcpd: added reverse map from 248.xxxx.xxx.10.in-addr.arpa. to nxxxxxh-PC.wifi-uhs.osu | 
| Apr 9 00:00:02 dh1 dhcpd: DHCPREQUEST for 10.xxx.xxx.248 from 00:x:5c:x:8c:xx (nxxxxh-PC) via 10.xxx.xxx.254 | 
| Apr 9 00:00:02 dh1 dhcpd: DHCPACK on 10.X.XX.248 to 00:X:5c:X8c:XX (nXXXich-PC) via 10.193.XX.XXX | 
| Apr 9 00:00:02 dh1 dhcpd: Added new forward map from XX.wifi-uhs.XXX to 10.X.X.242 | 
| Apr 9 00:00:02 dh1 dhcpd: added reverse map from 242.X.193.X.in-addr.arpa. to X.wifi-uhs.XXX | 
| Apr 9 00:00:02 dh1 dhcpd: DHCPREQUEST for 10.X.X.242 from 00:X:ce:X21:63 (elena) via 10.X.X.254 | 
| Apr 9 00:00:02 dh1 dhcpd: DHCPACK on 10.193.XXX.XX to 00:X:ce:X:21:63 (elena) via 10.X.X.254 | 
| Apr 9 00:00:02 dh1 dhcpd: Added new forward map from P305-XXX.wifi-uhs.XXX to 10.193.X.X | 
| Apr 9 00:00:02 dh1 dhcpd: added reverse map from 21.241.X.X.in-addr.arpa. to P305-XXXX.wifi-uhs.XXX | 

有日期，DH1之間的各種不同的人物和標籤，以及日誌條目本身。轉義這些角色會有問題嗎？我只是不太確定它是如何完成的。任何幫助，將不勝感激。

Answer 1

您尚未在字段中指定類型和格式。我猜你的php json實現不會生成一個javascript Date對象。

所以，儘量返回一個Unix時間戳，並以此作爲字段：

fields: [ 
    {name: 'ID', type: 'int'}, 
    {name: 'ReceivedAt', type: 'date', dateFormat: 'Y-m-d H:i:s'}, 
    'Message' 
] 

可選，你也可以指定一個dateFormat旁邊type: 'date'。 更多信息，請參閱文檔：http://www.sencha.com/deploy/dev/docs/?class=Ext.data.Field

{"dates":[{"ID":"18","ReceivedAt":"2010-07-07 11:37:42","Message":"Apr 9 00:00:03 dh1 dhcpd: added reverse map from 244.xxx.xxx.10.in-addr.arpa. to xxx.wifi-uhs.xxx"},{"ID":"19","ReceivedAt":"2010-07-07 11:37:42","Message":"Apr 9 00:00:03 dh1 dhcpd: DHCPREQUEST for 10.xxx.xxx.244 from 00:xx:f0:xx:d5:xxx (xxx) via xx.x.xxx.254"},{"ID":"20","ReceivedAt":"2010-07-07 11:37:42","Message":" [origin software="rsyslogd" swVersion="3.22.1" x-pid="5222" x-info="http://www.rsyslog.com"] (re)start"},{"ID":"21","ReceivedAt":"2010-07-07 11:37:42","Message":"WARNING: rsyslogd is running in compatibility mode.

[try http://www.rsyslog.com/e/2123 ]"},{"ID":"25","ReceivedAt":"2010-07-07 11:37:42","Message":"Warning: backward compatibility layer added to following directive to rsyslog.conf: ModLoad imuxsock"}]} 

其實我發現這個問題，它不是我的代碼。我限制了我的PHP只拉19條記錄，它的工作原理是，它在第​​20條記錄中，我得到了一個不同類型的日誌，它在我的網格上混亂並且什麼都不顯示。我認爲它與日誌中的特殊字符有關。

無論哪種方式，這是與Rsyslog，這是我用來將這些轉儲到MySQL的錯誤。不確定我是如何通過php/extjs修復它的。
