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 { 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 (
<div>
<Button type="primary" onClick={this.showModal}>
Open Modal
</Button>
<Modal
title="Basic Modal"
visible={this.state.visible}
onOk={this.handleOk}
onCancel={this.handleCancel}
>
<p>Some contents...</p>
<p>Some contents...</p>
<p>Some contents...</p>
</Modal>
</div>
);
}
}
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 (
<div>
<Button type="primary" onClick={this.showModal}>
Open Modal with customized footer
</Button>
<Modal
visible={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>,
]}
>
<p>Some contents...</p>
<p>Some contents...</p>
<p>Some contents...</p>
<p>Some contents...</p>
<p>Some contents...</p>
</Modal>
</div>
);
}
}
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 } 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: '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() {},
});
}
ReactDOM.render(<Button onClick={showConfirm}>Confirm</Button>, mountNode);
设置 okText
与 cancelText
以自定义按钮文字。
import { Modal, Button } 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 (
<div>
<Button type="primary" onClick={this.showModal}>
Modal
</Button>
<Modal
title="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>
</div>
);
}
}
function confirm() {
Modal.confirm({
title: 'Confirm',
icon: <ExclamationCircleOutlined />,
content: 'Bla bla ...',
okText: '确认',
cancelText: '取消',
});
}
ReactDOM.render(
<div>
<LocalizedModal />
<br />
<Button onClick={confirm}>Confirm</Button>
</div>,
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 (
<div>
<Button type="primary" onClick={() => this.setModal1Visible(true)}>
Display a modal dialog at 20px to Top
</Button>
<Modal
title="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>
<Modal
title="Vertically centered modal dialog"
centered
visible={this.state.modal2Visible}
onOk={() => this.setModal2Visible(false)}
onCancel={() => this.setModal2Visible(false)}
>
<p>some contents...</p>
<p>some contents...</p>
<p>some contents...</p>
</Modal>
</div>
);
}
}
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 (
<div>
<Button type="primary" onClick={this.showModal}>
Open Modal with customized button props
</Button>
<Modal
title="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>
</div>
);
}
}
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';
class App extends React.Component {
state = {
ModalText: 'Content of the modal',
visible: false,
confirmLoading: false,
};
showModal = () => {
this.setState({
visible: true,
});
};
handleOk = () => {
this.setState({
ModalText: 'The modal will be closed after two seconds',
confirmLoading: true,
});
setTimeout(() => {
this.setState({
visible: false,
confirmLoading: false,
});
}, 2000);
};
handleCancel = () => {
console.log('Clicked cancel button');
this.setState({
visible: false,
});
};
render() {
const { visible, confirmLoading, ModalText } = this.state;
return (
<div>
<Button type="primary" onClick={this.showModal}>
Open Modal with async logic
</Button>
<Modal
title="Title"
visible={visible}
onOk={this.handleOk}
confirmLoading={confirmLoading}
onCancel={this.handleCancel}
>
<p>{ModalText}</p>
</Modal>
</div>
);
}
}
ReactDOM.render(<App />, mountNode);
使用 confirm()
可以快捷地弹出确认框。
import { Modal, Button } 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 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(
<div>
<Button onClick={showConfirm}>Confirm</Button>
<Button onClick={showDeleteConfirm} type="dashed">
Delete
</Button>
<Button onClick={showPropsConfirm} type="dashed">
With extra props
</Button>
</div>,
mountNode,
);
各种类型的信息提示,只提供一个按钮用于关闭。
import { Modal, Button } 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(
<div>
<Button onClick={info}>Info</Button>
<Button onClick={success}>Success</Button>
<Button onClick={error}>Error</Button>
<Button onClick={warning}>Warning</Button>
</div>,
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(
<div>
<Button onClick={showConfirm}>Confirm</Button>
</div>,
mountNode,
);
通过 Modal.useModal
创建支持读取 context 的 contextHolder
。
import { Modal, Button } from 'antd';
const ReachableContext = React.createContext();
const UnreachableContext = React.createContext();
const config = {
title: 'Use Hook!',
content: (
<div>
<ReachableContext.Consumer>{name => `Reachable: ${name}!`}</ReachableContext.Consumer>
<br />
<UnreachableContext.Consumer>{name => `Unreachable: ${name}!`}</UnreachableContext.Consumer>
</div>
),
};
const App = () => {
const [modal, contextHolder] = Modal.useModal();
return (
<ReachableContext.Provider value="Light">
<Button
onClick={() => {
modal.confirm(config);
}}
>
Confirm
</Button>
<Button
onClick={() => {
modal.warning(config);
}}
>
Warning
</Button>
<Button
onClick={() => {
modal.info(config);
}}
>
Info
</Button>
<Button
onClick={() => {
modal.error(config);
}}
>
Error
</Button>
{/* `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);

const modal = Modal.info();
modal.update({
title: '修改的标题',
content: '修改的内容',
});
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 change
browserHistory.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?
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。
