                    items: editGoodsForm                }
            );
        //显示窗体
        editGoodsWin.show();
    };
右击editgrid行后，弹出菜单中执行此函数，报错"错误: 'this.el' 为空或不是对象",
求高手解答

1.把你要执行的内容放到外面去，每次都要创建window，form。先整理一下试试
2.form中还搞一个JsonReader干啥。要规范些
 reader: new Ext.data.JsonReader(
    { root: 'data' },
    [{ name: 'GoodsID', mapping: 'GoodsID', type: 'int' },
     { name: 'GoodsName', mapping: 'GoodsName', type: 'string' },
     { name: 'GoodsCode', mapping: 'GoodsCode', type: 'string' },
     { name: 'GoodsModel', mapping: 'GoodsModel', type: 'string' },
     { name: 'GoodsStandard', mapping: 'GoodsStandard', type: 'string' },
     { name: 'InPrice', mapping: 'InPrice', type: 'string' },
     { name: 'MUnit', mapping: 'MUnit', type: 'string' },
     { name: 'DUnit', mapping: 'DUnit', type: 'string' },
     { name: 'UnitRate', mapping: 'UnitRate', type: 'string' }
    ])
