extjs获取Container中Panel的checkbox

[竹子_bamboo]

获取下面代码，checkbox的值，我试了很多方法都取不到值

Ext.define("Biz.view.dblucene.alldatamodule.Container", {
    extend: 'Ext.container.Container',
    xtype: 'alldatamodule',
    requires: ['Ext.ux.layout.ResponsiveColumn'],
    controller: 'dashboard',
    viewModel: {
        type: 'dashboard'
    },
    layout: 'responsivecolumn',
    items: [{
        xtype: 'biz_tree', height: 400, title: '数据模型', rootVisible: true, root: {
            "id": "11111111-1111-1111-1111-111111111111", text: '组织目录', expanded: true
        }, store: Ext.create('Ext.data.TreeStore', {
            proxy: {
                extraParams: {"access": 1, "sort": "sort"},
                type: 'ajax',
                url: Ext.location + '/resource/datatableinfo/treeload'
            }
        }), listeners: {
            itemclick: function (dataView, node) {
                var grid = this.nextSibling();
                grid.getStore().removeAll();
                if (node.data.catalogId) {
                    Ext.apply(grid.getStore().getProxy(), {extraParams: {"parentid": node.id}});
                    grid.getStore().load();
                }
            }
        }
    }, {
        xtype: 'alltablegrid', height: 400, width: '70%', title: '字段列表'
    }]
});
Ext.define("Biz.view.dblucene.alldatamodule.TableGrid", {
    extend: "Biz.grid.Panel",
    xtype: 'alltablegrid',
    store: Ext.data.BizStore('/resource/datatableinfo/griddatafield'),
    scroll: true,
    defaults: {
        xtype: 'checkbox',
        id: 'hobby',
        typeAhead: true,
        triggerAction: 'all',
        selectOnFocus: true,
        labelAlign: 'right',
        width: '96%'
    },
    listeners: {
        afterrender: function () {
            this.getStore().setGroupField('tableName');
        }, cellclick: function (e, g, h, d) {
            var addToolbar = this.dockedItems.items[2].items.items[0];
            addToolbar.setDisabled(false);
            addToolbar.tableData = d.data;
            // var tableId = d.data.tableId;
            // var field = d.data.code;
            // var form = Ext.create("Biz.view.system.service.ServiceSourceForm");
            // form.getForm().findField('tableId').setValue(tableId);
            // form.getForm().findField('field').setValue(field);
        }
    },
    columns: [{
        text: "字段名称", dataIndex: 'name', flex: 0.25
    }, {
        text: "编码", dataIndex: 'code', width: 160
    }, {
        text: "字段类型", dataIndex: 'type', width: 100
    }, {
        text: "默认标识", dataIndex: 'defaultFlag', width: 80, renderer: function (value) {
            return {0: '否', 1: '是'}[value];
        }
    }, {
        text: "时间", dataIndex: 'createTime', width: 150, renderer: function (value) {
            return Ext.Date.format(new Date(value), "Y-m-d H:i:s");
        }
    }]
});

自己解决了 在xtype: 'alltablegrid',下面定义一个id，id: 'tablePanel',然后就可以取到了，比较笨的办法 代码如下：

var grid = Ext.getCmp('tablePanel');
            var rowSelectionModel = grid.getSelectionModel();
            if (rowSelectionModel.hasSelection()) {
                var field = '';
                var record = rowSelectionModel.getSelected().items;
                for (var i = 0; i < record.length; i++) {
                    var tableId = record[i].data.tableId;
                    var code = record[i].data.code;
                    if (i == 0) {
                        field += code;
                    } else {
                        field += ',' + code;
                    }
                }
                var json = {};
                json.tableId = tableId;
                json.fields = field;
                for (var j = 0; j < fields.length; j++) {
                    if (tableId == fields[j].tableId) {
                        fields.splice(j, 1);
                    }
                }
                fields.push(json);
            }
        }

完整的代码：

var fields = [];
Ext.define("Biz.view.dblucene.alldatamodule.TableGrid", {
    extend: "Ext.grid.Panel",
    xtype: 'alltablegrid',
    id: 'tablePanel',

    store: Ext.data.BizStore('/resource/datatableinfo/griddatafield'),
    scroll: true,
    defaults: {
        xtype: 'checkbox',
        typeAhead: true,
        triggerAction: 'all',
        selectOnFocus: true,
        labelAlign: 'right',
        width: '96%'
    },
    bbar: ['->', {
        xtype: 'button', text: '选定字段', width: '12%', style: 'border-color: #35baf6;', handler: function () {
            var grid = Ext.getCmp('tablePanel');
            var rowSelectionModel = grid.getSelectionModel();
            if (rowSelectionModel.hasSelection()) {
                var field = '';
                var record = rowSelectionModel.getSelected().items;
                for (var i = 0; i < record.length; i++) {
                    var tableId = record[i].data.tableId;
                    var code = record[i].data.code;
                    if (i == 0) {
                        field += code;
                    } else {
                        field += ',' + code;
                    }
                }
                var json = {};
                json.tableId = tableId;
                json.fields = field;
                for (var j = 0; j < fields.length; j++) {
                    if (tableId == fields[j].tableId) {
                        fields.splice(j, 1);
                    }
                }
                fields.push(json);
            }
        }
    }, '->'],
    listeners: {
        afterrender: function () {
            this.getStore().setGroupField('tableName');
        }, cellclick: function (e, g, h, d) {
            var addToolbar = this.dockedItems.items[2].items.items[0];
            addToolbar.setDisabled(false);
            addToolbar.tableData = d.data;
        }
    },
    columns: [{
        text: "字段名称", dataIndex: 'name', flex: 0.25
    }, {
        text: "编码", dataIndex: 'code', width: 160
    }, {
        text: "字段类型", dataIndex: 'type', width: 100
    }, {
        text: "默认标识", dataIndex: 'defaultFlag', width: 80, renderer: function (value) {
            return {0: '否', 1: '是'}[value];
        }
    }, {
        text: "时间", dataIndex: 'createTime', width: 150, renderer: function (value) {
            return Ext.Date.format(new Date(value), "Y-m-d H:i:s");
        }
    }]
});
