Modal对话框
模态对话框。
何时使用
需要用户处理事务,又不希望跳转页面以致打断工作流程时,可以使用 Modal 在当前页面正中打开一个浮层,承载相应的操作。
另外当需要一个简洁的确认框询问用户时,可以使用 Modal.confirm() 等语法糖方法。
代码演示

第一个对话框。
import React, { useState } from 'react';import { Modal, Button } from 'antd';const App = () => {const [isModalVisible, setIsModalVisible] = useState(false);const showModal = () => {setIsModalVisible(true);};const handleOk = () => {setIsModalVisible(false);};const handleCancel = () => {setIsModalVisible(false);};return (<><Button type="primary" onClick={showModal}>Open Modal</Button><Modal title="Basic Modal" visible={isModalVisible} onOk={handleOk} onCancel={handleCancel}><p>Some contents...</p><p>Some contents...</p><p>Some contents...</p></Modal></>);};ReactDOM.render(<App />, mountNode);

更复杂的例子,自定义了页脚的按钮,点击提交后进入 loading 状态,完成后关闭。
不需要默认确定取消按钮时,你可以把 footer 设为 null。
import { Modal, Button } from 'antd';class App extends React.Component {state = {loading: false,visible: false,};showModal = () => {this.setState({visible: true,});};handleOk = () => {this.setState({ loading: true });setTimeout(() => {this.setState({ loading: false, visible: false });}, 3000);};handleCancel = () => {this.setState({ visible: false });};render() {const { visible, loading } = this.state;return (<><Button type="primary" onClick={this.showModal}>Open Modal with customized footer</Button><Modalvisible={visible}title="Title"onOk={this.handleOk}onCancel={this.handleCancel}footer={[<Button key="back" onClick={this.handleCancel}>Return</Button>,<Button key="submit" type="primary" loading={loading} onClick={this.handleOk}>Submit</Button>,<Buttonkey="link"href="https://google.com"type="primary"loading={loading}onClick={this.handleOk}>Search on Google</Button>,]}><p>Some contents...</p><p>Some contents...</p><p>Some contents...</p><p>Some contents...</p><p>Some contents...</p></Modal></>);}}ReactDOM.render(<App />, mountNode);

各种类型的信息提示,只提供一个按钮用于关闭。
import { Modal, Button, Space } from 'antd';function info() {Modal.info({title: 'This is a notification message',content: (<div><p>some messages...some messages...</p><p>some messages...some messages...</p></div>),onOk() {},});}function success() {Modal.success({content: 'some messages...some messages...',});}function error() {Modal.error({title: 'This is an error message',content: 'some messages...some messages...',});}function warning() {Modal.warning({title: 'This is a warning message',content: 'some messages...some messages...',});}ReactDOM.render(<Space><Button onClick={info}>Info</Button><Button onClick={success}>Success</Button><Button onClick={error}>Error</Button><Button onClick={warning}>Warning</Button></Space>,mountNode,);

手动更新和关闭 Modal.method 方式创建的对话框。
import { Modal, Button } from 'antd';function countDown() {let secondsToGo = 5;const modal = Modal.success({title: 'This is a notification message',content: `This modal will be destroyed after ${secondsToGo} second.`,});const timer = setInterval(() => {secondsToGo -= 1;modal.update({content: `This modal will be destroyed after ${secondsToGo} second.`,});}, 1000);setTimeout(() => {clearInterval(timer);modal.destroy();}, secondsToGo * 1000);}ReactDOM.render(<Button onClick={countDown}>Open modal to close in 5s</Button>, mountNode);

使用 Modal.destroyAll() 可以销毁弹出的确认窗。通常用于路由监听当中,处理路由前进、后退不能销毁确认对话框的问题。
import { Modal, Button } from 'antd';import { ExclamationCircleOutlined } from '@ant-design/icons';function destroyAll() {Modal.destroyAll();}const { confirm } = Modal;function showConfirm() {for (let i = 0; i < 3; i += 1) {setTimeout(() => {confirm({icon: <ExclamationCircleOutlined />,content: <Button onClick={destroyAll}>Click to destroy all</Button>,onOk() {console.log('OK');},onCancel() {console.log('Cancel');},});}, i * 500);}}ReactDOM.render(<Button onClick={showConfirm}>Confirm</Button>, mountNode);

通过 Modal.useModal 创建支持读取 context 的 contextHolder。
import { Modal, Button, Space } from 'antd';const ReachableContext = React.createContext();const UnreachableContext = React.createContext();const config = {title: 'Use Hook!',content: (<><ReachableContext.Consumer>{name => `Reachable: ${name}!`}</ReachableContext.Consumer><br /><UnreachableContext.Consumer>{name => `Unreachable: ${name}!`}</UnreachableContext.Consumer></>),};const App = () => {const [modal, contextHolder] = Modal.useModal();return (<ReachableContext.Provider value="Light"><Space><ButtononClick={() => {modal.confirm(config);}}>Confirm</Button><ButtononClick={() => {modal.warning(config);}}>Warning</Button><ButtononClick={() => {modal.info(config);}}>Info</Button><ButtononClick={() => {modal.error(config);}}>Error</Button></Space>{/* `contextHolder` should always under the context you want to access */}{contextHolder}{/* Can not access this context since `contextHolder` is not in it */}<UnreachableContext.Provider value="Bamboo" /></ReachableContext.Provider>);};ReactDOM.render(<App />, mountNode);

使用 width 来设置模态对话框的宽度。
import React, { useState } from 'react';import { Modal, Button } from 'antd';const App = () => {const [visible, setVisible] = useState(false);return (<><Button type="primary" onClick={() => setVisible(true)}>Open Modal of 1000px width</Button><Modaltitle="Modal 1000px width"centeredvisible={visible}onOk={() => setVisible(false)}onCancel={() => setVisible(false)}width={1000}><p>some contents...</p><p>some contents...</p><p>some contents...</p></Modal></>);};ReactDOM.render(<App />, mountNode);

点击确定后异步关闭对话框,例如提交表单。
import { Modal, Button } from 'antd';const App = () => {const [visible, setVisible] = React.useState(false);const [confirmLoading, setConfirmLoading] = React.useState(false);const [modalText, setModalText] = React.useState('Content of the modal');const showModal = () => {setVisible(true);};const handleOk = () => {setModalText('The modal will be closed after two seconds');setConfirmLoading(true);setTimeout(() => {setVisible(false);setConfirmLoading(false);}, 2000);};const handleCancel = () => {console.log('Clicked cancel button');setVisible(false);};return (<><Button type="primary" onClick={showModal}>Open Modal with async logic</Button><Modaltitle="Title"visible={visible}onOk={handleOk}confirmLoading={confirmLoading}onCancel={handleCancel}><p>{modalText}</p></Modal></>);};ReactDOM.render(<App />, mountNode);

使用 confirm() 可以快捷地弹出确认框。onCancel/onOk 返回 promise 可以延迟关闭。
import { Modal, Button, Space } from 'antd';import { ExclamationCircleOutlined } from '@ant-design/icons';const { confirm } = Modal;function showConfirm() {confirm({title: 'Do you Want to delete these items?',icon: <ExclamationCircleOutlined />,content: 'Some descriptions',onOk() {console.log('OK');},onCancel() {console.log('Cancel');},});}function showPromiseConfirm() {confirm({title: 'Do you want to delete these items?',icon: <ExclamationCircleOutlined />,content: 'When clicked the OK button, this dialog will be closed after 1 second',onOk() {return new Promise((resolve, reject) => {setTimeout(Math.random() > 0.5 ? resolve : reject, 1000);}).catch(() => console.log('Oops errors!'));},onCancel() {},});}function showDeleteConfirm() {confirm({title: 'Are you sure delete this task?',icon: <ExclamationCircleOutlined />,content: 'Some descriptions',okText: 'Yes',okType: 'danger',cancelText: 'No',onOk() {console.log('OK');},onCancel() {console.log('Cancel');},});}function showPropsConfirm() {confirm({title: 'Are you sure delete this task?',icon: <ExclamationCircleOutlined />,content: 'Some descriptions',okText: 'Yes',okType: 'danger',okButtonProps: {disabled: true,},cancelText: 'No',onOk() {console.log('OK');},onCancel() {console.log('Cancel');},});}ReactDOM.render(<Space><Button onClick={showConfirm}>Confirm</Button><Button onClick={showPromiseConfirm}>With promise</Button><Button onClick={showDeleteConfirm} type="dashed">Delete</Button><Button onClick={showPropsConfirm} type="dashed">With extra props</Button></Space>,mountNode,);

设置 okText 与 cancelText 以自定义按钮文字。
import { Modal, Button, Space } from 'antd';import { ExclamationCircleOutlined } from '@ant-design/icons';class LocalizedModal extends React.Component {state = { visible: false };showModal = () => {this.setState({visible: true,});};hideModal = () => {this.setState({visible: false,});};render() {return (<><Button type="primary" onClick={this.showModal}>Modal</Button><Modaltitle="Modal"visible={this.state.visible}onOk={this.hideModal}onCancel={this.hideModal}okText="确认"cancelText="取消"><p>Bla bla ...</p><p>Bla bla ...</p><p>Bla bla ...</p></Modal></>);}}function confirm() {Modal.confirm({title: 'Confirm',icon: <ExclamationCircleOutlined />,content: 'Bla bla ...',okText: '确认',cancelText: '取消',});}ReactDOM.render(<Space><LocalizedModal /><Button onClick={confirm}>Confirm</Button></Space>,mountNode,);

使用 centered 或类似 style.top 的样式来设置对话框位置。
import { Modal, Button } from 'antd';class App extends React.Component {state = {modal1Visible: false,modal2Visible: false,};setModal1Visible(modal1Visible) {this.setState({ modal1Visible });}setModal2Visible(modal2Visible) {this.setState({ modal2Visible });}render() {return (<><Button type="primary" onClick={() => this.setModal1Visible(true)}>Display a modal dialog at 20px to Top</Button><Modaltitle="20px to Top"style={{ top: 20 }}visible={this.state.modal1Visible}onOk={() => this.setModal1Visible(false)}onCancel={() => this.setModal1Visible(false)}><p>some contents...</p><p>some contents...</p><p>some contents...</p></Modal><br /><br /><Button type="primary" onClick={() => this.setModal2Visible(true)}>Vertically centered modal dialog</Button><Modaltitle="Vertically centered modal dialog"centeredvisible={this.state.modal2Visible}onOk={() => this.setModal2Visible(false)}onCancel={() => this.setModal2Visible(false)}><p>some contents...</p><p>some contents...</p><p>some contents...</p></Modal></>);}}ReactDOM.render(<App />, mountNode);

传入 okButtonProps 和 cancelButtonProps 可分别自定义确定按钮和取消按钮的 props。
import { Modal, Button } from 'antd';class App extends React.Component {state = { visible: false };showModal = () => {this.setState({visible: true,});};handleOk = e => {console.log(e);this.setState({visible: false,});};handleCancel = e => {console.log(e);this.setState({visible: false,});};render() {return (<><Button type="primary" onClick={this.showModal}>Open Modal with customized button props</Button><Modaltitle="Basic Modal"visible={this.state.visible}onOk={this.handleOk}onCancel={this.handleCancel}okButtonProps={{ disabled: true }}cancelButtonProps={{ disabled: true }}><p>Some contents...</p><p>Some contents...</p><p>Some contents...</p></Modal></>);}}ReactDOM.render(<App />, mountNode);

自定义渲染对话框, 可通过 react-draggable 来实现拖拽。
import { Modal, Button } from 'antd';import Draggable from 'react-draggable';class App extends React.Component {state = {visible: false,disabled: true,bounds: { left: 0, top: 0, bottom: 0, right: 0 },};draggleRef = React.createRef();showModal = () => {this.setState({visible: true,});};handleOk = e => {console.log(e);this.setState({visible: false,});};handleCancel = e => {console.log(e);this.setState({visible: false,});};onStart = (event, uiData) => {const { clientWidth, clientHeight } = window?.document?.documentElement;const targetRect = this.draggleRef?.current?.getBoundingClientRect();this.setState({bounds: {left: -targetRect?.left + uiData?.x,right: clientWidth - (targetRect?.right - uiData?.x),top: -targetRect?.top + uiData?.y,bottom: clientHeight - (targetRect?.bottom - uiData?.y),},});};render() {const { bounds, disabled, visible } = this.state;return (<><Button onClick={this.showModal}>Open Draggable Modal</Button><Modaltitle={<divstyle={{width: '100%',cursor: 'move',}}onMouseOver={() => {if (disabled) {this.setState({disabled: false,});}}}onMouseOut={() => {this.setState({disabled: true,});}}// fix eslintjsx-a11y/mouse-events-have-key-events// https://github.com/jsx-eslint/eslint-plugin-jsx-a11y/blob/master/docs/rules/mouse-events-have-key-events.mdonFocus={() => {}}onBlur={() => {}}// end>Draggable Modal</div>}visible={visible}onOk={this.handleOk}onCancel={this.handleCancel}modalRender={modal => (<Draggabledisabled={disabled}bounds={bounds}onStart={(event, uiData) => this.onStart(event, uiData)}><div ref={this.draggleRef}>{modal}</div></Draggable>)}><p>Just don't learn physics at school and your life will be full of magic andmiracles.</p><br /><p>Day before yesterday I saw a rabbit, and yesterday a deer, and today, you.</p></Modal></>);}}ReactDOM.render(<App />, mountNode);

注意
<Modal />默认关闭后状态不会自动清空, 如果希望每次打开都是新内容,请设置destroyOnClose。<Modal />和 Form 一起配合使用时,设置destroyOnClose也不会在 Modal 关闭时销毁表单字段数据,需要设置<Form preserve={false} />。Modal.method()RTL 模式仅支持 hooks 用法。
Modal.method()
包括:
Modal.infoModal.successModal.errorModal.warningModal.confirm
以上均为一个函数,参数为 object,具体属性如下:

以上函数调用后,会返回一个引用,可以通过该引用更新和关闭弹窗。
const modal = Modal.info();modal.update({title: '修改的标题',content: '修改的内容',});// 在 4.8.0 或更高版本中,可以通过传入函数的方式更新弹窗modal.update(prevConfig => ({...prevConfig,title: `${prevConfig.title}(新)`,}));modal.destroy();
Modal.destroyAll
使用 Modal.destroyAll() 可以销毁弹出的确认窗(即上述的 Modal.info、Modal.success、Modal.error、Modal.warning、Modal.confirm)。通常用于路由监听当中,处理路由前进、后退不能销毁确认对话框的问题,而不用各处去使用实例的返回值进行关闭(modal.destroy() 适用于主动关闭,而不是路由这样被动关闭)
import { browserHistory } from 'react-router';// router changebrowserHistory.listen(() => {Modal.destroyAll();});
Modal.useModal()
当你需要使用 Context 时,可以通过 Modal.useModal 创建一个 contextHolder 插入子节点中。通过 hooks 创建的临时 Modal 将会得到 contextHolder 所在位置的所有上下文。创建的 modal 对象拥有与 Modal.method) 相同的创建通知方法。
const [modal, contextHolder] = Modal.useModal();React.useEffect(() => {modal.confirm({// ...});}, []);return <div>{contextHolder}</div>;
FAQ
为什么 Modal 方法不能获取 context、redux、的内容和 ConfigProvider locale/prefixCls 配置?
直接调用 Modal 方法,antd 会通过 ReactDOM.render 动态创建新的 React 实体。其 context 与当前代码所在 context 并不相同,因而无法获取 context 信息。
当你需要 context 信息(例如 ConfigProvider 配置的内容)时,可以通过 Modal.useModal 方法会返回 modal 实体以及 contextHolder 节点。将其插入到你需要获取 context 位置即可:
const [modal, contextHolder] = Modal.useModal();return (<Context1.Provider value="Ant">{/* contextHolder 在 Context1 内,它可以获得 Context1 的 context */}{contextHolder}<Context2.Provider value="Design">{/* contextHolder 在 Context2 外,因而不会获得 Context2 的 context */}</Context2.Provider></Context1.Provider>);
异同:通过 hooks 创建的 contextHolder 必须插入到子元素节点中才会生效,当你不需要上下文信息时请直接调用。
如何关闭 Modal 动画?
你可以通过 transitionName="" 和 maskTransitionName="" 去除动画 CSS,但是需要注意的是。该方法为内部方法,我们不保证下个大版本重构时该属性会被保留。
静态方法如何设置 prefixCls ?
你可以通过 ConfigProvider.config-4.13.0+) 进行设置。
