您需要通过引用 el 元素来添加事件。

editor: {
        xtype: 'textfield',
        enableKeyEvents: true,
        listeners: {
            keyup: {
                element: 'el',
                fn: function (a, b) {
                    var record = gridStore.getSelectionModel().selected.items[0].data
                    alert(record);
                }
            }
        }
    }
