Extjs 4.2 在控制器中编辑存储数据

Question

我有一个网格，其中的数据是我用其他商店的数据手动填充的：

fillfunction:function(){
    var Store=Ext.ComponentQuery.query('#grid')[0].getStore();
    var Store2=Ext.ComponentQuery.query('#grid2')[0].getStore();
    Store.each(function(record){
        var record=Ext.create('App.model.record');
        record.data['Referencia_proveedor']=record.data['codigo_erp_producto'];
        record.data['Especialidad']=record.data['nombre_comercial_1'];
        record.data['Presentacion']=record.data['forma_presentacion'];


        record.data['Porc_real_decreto']=record.data['porcentaje_real_decreto'];
        record.data['ADJ']=false;
        Store2.add(record);
    });
}

此网格有 selType：'checkboxmodel'，我有一个按钮可以更改存储中的数据['ADJ']（在模型中此列类型是布尔值）从假到真。我用下一个代码编辑数据：

changeValue:function(){
    var selection=Ext.ComponentQuery.query('#grid2')[0].getSelectionModel().getSelection();
    for (i = 0; i < selection.length; i++){
        var index=Ext.ComponentQuery.query('#grid2')[0].getStore().indexOf(selection[i]);
        var record=Ext.ComponentQuery.query('#grid2')[0].getStore().getAt(index);
        record.set('ADJ',true);
    }

    var total=Ext.ComponentQuery.query('#grid2')[0].getStore().count();
    var alterstore=Ext.ComponentQuery.query('#grid2')[0].getStore().getRange(0,total);
    Ext.ComponentQuery.query('#grid2')[0].getStore().loadRecords(alterstore,{addRecords: false});
}

如果我再次打印 ADJ 的存储值已更新，但网格中仍然是旧值 value.How 我可以更新网格以查看新值吗？

var panel1=new Ext.grid.Panel({
        itemId:'panel1',
        flex:3,
        store: store,
        title:'<span style="color:blue">Title 1</span>',
        scroll:'vertical',
        stripeRows: true,
        selModel: {
            selType: 'checkboxmodel'
        },
        bbar:{
            xtype: 'container',
            layout: 'anchor',
            items: [bottombar0]
        },
        loadMask: true,
        columns:{
            items:[

                   {header:'<span>R</span>',dataIndex:'Referencia_proveedor',itemId:'',flex:1},
                   {header:'<span>A</span>',dataIndex:'Especialidad',itemId:'',flex:3},
                   {header:'<span>P</span>',dataIndex:'Presentacion',itemId:'',flex:1},
                   {header:'<span>U</span>',dataIndex:'',align:'right',itemId:'',flex:1,renderer:Unidades},
                   {header:'<span>PVL</span>',dataIndex:'',align:'right',itemId:'',flex:2,renderer:Moneda},
                   {header:'<span>RD</span>',dataIndex:'Porc_real_decreto',align:'right',itemId:'',flex:1,renderer:Porcentaje},
                   {header:'<span>ADJ</span>',dataIndex:'',align:'center',itemId:'',flex:1,renderer:adjudicado}
            ]
        }
    });

Answer 1

很简单，我打错了

{header:'<span>ADJ</span>',dataIndex:'',align:'center',itemId:'',flex:1,renderer:adjudicado}

这里忘记设置dataIndex为：

{header:'<span>ADJ</span>',dataIndex:'ADJ',align:'center',itemId:'',flex:1,renderer:adjudicado}

忘记设置字段的dataIndex dataIndex:'ADJ'

接下来我在控制器中执行：

changeValue:function(){
    var selection=Ext.ComponentQuery.query('#grid2')[0].getSelectionModel().getSelection();
    for (i = 0; i < selection.length; i++){
        var index=Ext.ComponentQuery.query('#grid2')[0].getStore().indexOf(selection[i]);
        var record=Ext.ComponentQuery.query('#grid2')[0].getStore().getAt(index);
        record.set('ADJ',true);
    }
Ext.ComponentQuery.query('#grid2')[0].getStore().commitChanges();

然后网格中的值 refresh.I 执行 commitChanges 以清除脏字段。
