Javascript ExtJS网格未从Ext.data.XmlStore加载数据

我有一个网格，我正试图从一个XmlStore填充它，它是从一个Xml字符串填充的。到目前为止，存储似乎可以加载XML，但我无法让网格加载存储。（即grid.getStore（）.getCount（）始终为0

// create the Data Stores for use by the grid
Ext.define('InterfaceModel', {
    extend: 'Ext.data.Model',
    fields: [
        { name: 'id', mapping: 'id' },
        { name: 'InterfaceName', mapping: 'InterfaceName' },
        { name: 'TX_OCTETS', mapping: 'TX_OCTETS' },
        { name: 'TX_BAD_OCTETS', mapping: 'TX_BAD_OCTETS' },
        { name: 'TX_FRM', mapping: 'TX_FRM' },
        { name: 'TX_BAD_FRM', mapping: 'TX_BAD_FRM' },
        { name: 'TX_MCAST', mapping: 'TX_MCAST' },
        { name: 'TX_BCAST', mapping: 'TX_BCAST' },
        { name: 'TX_PAUSE', mapping: 'TX_PAUSE' }
    ],
    idProperty: 'id'
});

我的XML如下所示：

var gridData = '<?xml version="1.0" encoding="UTF-8"?> <Interfaces> <Interface> <id>1</id> <InterfaceName>GMAC1</InterfaceName> <TX_OCTETS>123234</TX_OCTETS> <TX_BAD_OCTETS>234</TX_BAD_OCTETS> <TX_FRM>234234</TX_FRM> <TX_BAD_FRM>2341</TX_BAD_FRM> <TX_MCAST>23</TX_MCAST> <TX_BCAST>56</TX_BCAST> <TX_PAUSE>8</TX_PAUSE></Interface> <Interface> <id>2</id> <InterfaceName>GMAC2</InterfaceName> <TX_OCTETS>123234</TX_OCTETS> <TX_BAD_OCTETS>234</TX_BAD_OCTETS> <TX_FRM>234234</TX_FRM> <TX_BAD_FRM>2341</TX_BAD_FRM> <TX_MCAST>23</TX_MCAST> <TX_BCAST>56</TX_BCAST> <TX_PAUSE>8</TX_PAUSE></Interface></Interfaces>';

var gridDataXml = (new DOMParser()).parseFromString(gridData,'text/xml');

console.log ('xml', gridDataXml);  // everything looks fine

createGrid: function () {
    var me = this;

    return {
        id: 'eioaGrid',
        xtype: 'grid',
        border: true,
        store: this.eioaGridStore,
        columns: [{

                dataIndex: 'TX_BAD_OCTETS',
                tooltip: 'Transmitted'
            }]
        }, {
            text: 'FRAMES',
            sortable: false,
            width: 100,
            tooltip: 'Total number of frames.',
            columns: [{

        }, {

            width: 100,
            tooltip: 'Total number of bad frames.',
            columns: [{
                header: 'TX',

                sortable: true,
                dataIndex: 'TX_BAD_FRM',
                tooltip: 'Transmitted'
            }]
        }, {
            text: 'MULTICAST',
            sortable: false,
            width: 100,
            tooltip: 'Multicast Frames: good non-pause frames with a multicast destination address which is not the broadcast address.',
            columns: [{
                header: 'TX',
                width: 50,
                align: 'center',
                sortable: true,
                dataIndex: 'TX_MCAST',
                tooltip: 'Transmitted'
            }]
        }, {
            text: 'BROADCAST',
            sortable: false,
            width: 100,
            tooltip: 'Broadcast Frames: good frames with the broadcast destination address.',
            columns: [{
                header: 'TX',
                width: 50,
                align: 'center',
                sortable: true,
                dataIndex: 'TX_BCAST',
                tooltip: 'Transmitted'
            }]
        }, {
            text: 'PAUSE',
            sortable: false,
            width: 100,
            tooltip: 'Pause Frames: pause frames internally generated by the MAC.',
            columns: [{
                header: 'TX',
                width: 50,
                align: 'center',
                sortable: true,
                dataIndex: 'TX_PAUSE',
                tooltip: 'Transmitted'
            }]
        }]
    };
}

然后将解析后的XML DOM加载到存储中：

eioaGridStore.loadRawData(gridDataXml);

如果我在存储上获取count（），它会正确地响应2

从Web Inspector查看存储时显示2个数组（我希望是网格中的行）（请原谅格式）

我的网格组件如下所示：

var gridData = '<?xml version="1.0" encoding="UTF-8"?> <Interfaces> <Interface> <id>1</id> <InterfaceName>GMAC1</InterfaceName> <TX_OCTETS>123234</TX_OCTETS> <TX_BAD_OCTETS>234</TX_BAD_OCTETS> <TX_FRM>234234</TX_FRM> <TX_BAD_FRM>2341</TX_BAD_FRM> <TX_MCAST>23</TX_MCAST> <TX_BCAST>56</TX_BCAST> <TX_PAUSE>8</TX_PAUSE></Interface> <Interface> <id>2</id> <InterfaceName>GMAC2</InterfaceName> <TX_OCTETS>123234</TX_OCTETS> <TX_BAD_OCTETS>234</TX_BAD_OCTETS> <TX_FRM>234234</TX_FRM> <TX_BAD_FRM>2341</TX_BAD_FRM> <TX_MCAST>23</TX_MCAST> <TX_BCAST>56</TX_BCAST> <TX_PAUSE>8</TX_PAUSE></Interface></Interfaces>';

var gridDataXml = (new DOMParser()).parseFromString(gridData,'text/xml');

console.log ('xml', gridDataXml);  // everything looks fine

createGrid: function () {
    var me = this;

    return {
        id: 'eioaGrid',
        xtype: 'grid',
        border: true,
        store: this.eioaGridStore,

                tooltip: 'Transmitted'
            }]
        }]
    };
}

稍后，我通过网格的存储获取getCount（），它返回为空

console.log('grid store count', Ext.getCmp('eioaGrid').store.getCount());

有什么想法吗？已经被难倒了几天了，我快疯了！谢谢。

只是一个猜测，因为我没有加载你的代码，但是可能会从商店定义中删除自动加载，因为你是手动操作的？

我刚找到它…我在设置网格存储时对该.eioaGridStore的引用：不在范围内（未定义）…一切都正常。
