我有这两个组成部分:BasicMaintainer
// etc...
import GeneratingUnit from "./generating-unit";
class BasicMaintainer extends Component {
constructor(props) {
super(props);
// etc...
}
// etc...
handleOnSelectFile = event => {
here I want to use: GeneratingUnit.columns.length
}
其他组件
GeneratingUnit
是:import React from 'react';
//...code
export const columns = [
{name: 'ID', numeric: false, disablePadding: true, key: 'id'},
{name: 'NOMBRE', numeric: false, disablePadding: true, key: 'nombre'},
{name: 'DESCRIPCIÓN', numeric: false, disablePadding: true, key: 'descripcion'},
{name: 'IT UNIDAD GENERADORA', numeric: false, disablePadding: true, key: 'it_unidad_generadora'},
]
const GeneratingUnit = props => <div>
//code...
</div>
export default GeneratingUnit;
如何在
const columns
组件的handleOnSelectFile
中使用BasicMaintainer
? 最佳答案
将其导入您的BasicMaintainer
文件:
import GeneratingUnit, {columns} from "./generating-unit";
关于javascript - react ,从另一个组件读取const,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/59665432/
