--- order: 4 title: zh-CN: Promise 接口 en-US: Promise interface --- ## zh-CN 可以通过 then 接口在关闭后运行 callback 。以上用例将在每个 message 将要结束时通过 then 显示新的 message 。 ## en-US `message` provides a promise interface for `onClose`. The above example will display a new message when the old message is about to close. ```tsx import { Button, message } from 'antd'; import React from 'react'; const App: React.FC = () => { const [messageApi, contextHolder] = message.useMessage(); const success = () => { messageApi .open({ type: 'loading', content: 'Action in progress..', duration: 2.5, }) .then(() => message.success('Loading finished', 2.5)) .then(() => message.info('Loading finished', 2.5)); }; return ( <> {contextHolder} ); }; export default App; ```
