extjs - 分页现在在 extjs 4.1 网格分页中显示 Total

Question

我注意到在某些或我的网格上没有显示“displayMsg”。即右下角的文字。

如果你看下面的屏幕截图，我已经设置了 pageSize： 4. 总共有“33”条记录，所以应该开始分页。一般来说，分页不显示记录总数的原因是什么。

Ext.define('Mis.view.PurchaseOrder', {
extend: 'Ext.grid.Panel',
alias:'widget.purchaseorder',
title:'Purchase Order',
store:'MaterialPurchaseOrders',
height: 235,
dockedItems:[
    {
        xtype: 'pagingtoolbar',
        store:'MaterialPurchaseOrders',
        dock: 'bottom',
        displayInfo: true,
        displayMsg:'Displaying records {0} - {1} of {2}  ',
        emptyMsg:"No records to display ",
        flex:1
    }
],
columns:[
    {
        xtype:'gridcolumn',
        dataIndex:'PartName',
        name:'PartName',
        text:'Part',
        flex:1
    },
    {
        xtype:'gridcolumn',
        text:'PO ID',
        dataIndex:'PoNumber',
        name:'PoNumber',
        width: 80,
        align: 'center'
    },
    {
        xtype:'gridcolumn',
        text:'Material',
        dataIndex:'Name',
        name:'Name',
        flex:1
    },
    {
        xtype:'gridcolumn',
        text:'Total',
        dataIndex:'Total',
        name:'Total',
        width: 80,
        align: 'center'
    },
    {
        xtype:'gridcolumn',
        text:'Size / Ref',
        dataIndex:'SizeReference',
        name:'SizeReference',
        width: 80,
        align: 'center'
    },
    {
        xtype:'gridcolumn',
        text:'Size L',
        dataIndex:'SizeLength',
        name:'SizeLength',
        width: 80,
        align: 'center'
    },
    {
        xtype:'gridcolumn',
        text:'Size W',
        dataIndex:'SizeWidth',
        name:'SizeWidth',
        width: 80,
        align: 'center'
    },
    {
        xtype:'gridcolumn',
        text:'Quantity',
        dataIndex:'Quantity',
        name:'Quantity',
        width: 80,
        align: 'center'
    },
    {
        xtype:'gridcolumn',
        text:'Meterage',
        dataIndex:'Meterage',
        name:'Meterage',
        width: 80,
        align: 'center'
    }
],


initComponent:function () {
    this.callParent();
}

});

尝试为您的商店创建一个实例，这样做从来都不是坏事。使用您的示例（按字符串存储），如果您打开了 2 个网格并对它们进行排序，它们将排序相同，等等...

Ext.define('Mis.view.PurchaseOrder', {
    extend: 'Ext.grid.Panel',
    alias: 'widget.purchaseorder',
    title: 'Purchase Order',
    height: 235,
    columns: [
        {
        xtype: 'gridcolumn',
        dataIndex: 'PartName',
        name: 'PartName',
        text: 'Part',
        flex: 1},
    {
        xtype: 'gridcolumn',
        text: 'PO ID',
        dataIndex: 'PoNumber',
        name: 'PoNumber',
        width: 80,
        align: 'center'},
    {
        xtype: 'gridcolumn',
        text: 'Material',
        dataIndex: 'Name',
        name: 'Name',
        flex: 1},
    {
        xtype: 'gridcolumn',
        text: 'Total',
        dataIndex: 'Total',
        name: 'Total',
        width: 80,

        dataIndex: 'Meterage',

    ],
    initComponent: function() {
        var me = this;
        var store = Ext.create('Mis.store.MaterialPurchaseOrders');

        Ext.applyIf(me, {
            store: store,
            dockedItems: [{

                displayInfo: true,
                displayMsg: 'Displaying records {0} - {1} of {2}  ',
                emptyMsg: "No records to display ",
                flex: 1}]
        });
        me.callParent();
    }
});​
