包括成功、失败、警告
import React from 'react';
import { Toast, Button } from '@douyinfe/semi-ui';
function Demo() {
let opts = {
content: 'Hi, Bytedance dance dance',
duration: 3,
};
return (
<>
<Button style={{color:`var(--semi-color-success)`}} onClick={() => Toast.success('Hi,Bytedance dance dance')}>Success</Button>
<br />
<br />
<Button type="warning" onClick={() => Toast.warning(opts)}>
Warning
</Button>
<br />
<br />
<Button type="danger" onClick={() => Toast.error(opts)}>
Error
</Button>
</>
);
}
render(Demo);
可以使用 theme 设置浅色填充样式提高与界面的对比,默认为 'normal' 的白色模式。
import React from 'react';
import { Toast, Button } from '@douyinfe/semi-ui';
function Demo() {
let opts = {
content: 'Hi, Bytedance dance dance',
duration: 3,
theme: 'light',
};
return (
<>
<Button onClick={() => Toast.info(opts)}>Info</Button>
<br />
<br />
<Button style={{color:`var(--semi-color-success)`}} onClick={() => Toast.success(opts)}>Success</Button>
<br />
<br />
<Button type="warning" onClick={() => Toast.warning(opts)}>
Warning
</Button>
<br />
<br />
<Button type="danger" onClick={() => Toast.error(opts)}>
Error
</Button>
</>
);
}
render(Demo);
配合 Typography 可以自定义链接文本,用来配合更复杂的场景的使用。
import React from 'react';
import { Toast, Typography, Button } from '@douyinfe/semi-ui';
function Demo() {
const { Text } = Typography;
let opts = {
content: (
<span>
<Text>Hi, Bytedance dance dance</Text>
<Text link style={{ marginLeft: 12 }}>
更多
</Text>
</span>
),
duration: 3,
};
let multiLineOpts = {
content: (
<>
<div>Hi, Bytedance dance dance</div>
<div style={{ marginTop: 8 }}>
<Text link>查看详情</Text>
<Text link style={{ marginLeft: 20 }}>
一会再看
</Text>
</div>
</>
),
duration: 3,
};
return (
<>
<Button onClick={() => Toast.info(opts)}>Display Toast</Button>
<br />
<br />
<Button onClick={() => Toast.info(multiLineOpts)}>Display Multi-line Toast</Button>
</>
);
}
render(Demo);
自定义时长 10s,默认时长为 3s
import React from 'react';
import { Toast, Button } from '@douyinfe/semi-ui';
function Demo() {
let opts = {
content: 'Hi, Bytedance dance dance',
duration: 10,
};
return <Button onClick={() => Toast.info(opts)}>Close After 10s</Button>;
}
render(Demo);
当 duration 设置为 0 时,toast 不会自动关闭,此时必须通过手动关闭。
import React, { useState } from 'react';
import { Toast, Button } from '@douyinfe/semi-ui';
function Demo() {
const [toastId, setToastId] = useState();
function show() {
if (toastId) {
return;
}
let id = Toast.info(opts);
setToastId(id);
}
function hide() {
Toast.close(toastId);
destroy();
}
function destroy() {
setToastId(null);
}
let opts = {
content: 'Not auto close',
duration: 0,
onClose: destroy,
};
return (
<>
<Button type="primary" onClick={show}>
Show Toast
</Button>
<br />
<br />
<Button type="primary" onClick={hide}>
Hide Toast
</Button>
</>
);
}
render(Demo);
通过 Toast.useToast 创建支持读取 context 的 contextHolder。此时的 toast 会渲染在 contextHolder 所在的节点处。
import React from 'react';
import { Toast, Button } from '@douyinfe/semi-ui';
const ReachableContext = React.createContext();
function Demo(props = {}) {
const [toast, contextHolder] = Toast.useToast();
const config = {
duration: 0,
title: 'This is a success message',
content: <ReachableContext.Consumer>{name => `ReachableContext: ${name}`}</ReachableContext.Consumer>,
};
return (
<ReachableContext.Provider value="Light">
<div>
<Button
onClick={() => {
toast.success(config);
}}
>
Hook Toast
</Button>
</div>
{contextHolder}
</ReachableContext.Provider>
);
}
render(Demo);
如果需要渲染到 Portal 中可以使用 ReactDOM.createPortal 方法。
import React, { useRef } from 'react';
import { Toast, Button } from '@douyinfe/semi-ui';
const ReachableContext = React.createContext();
const useCreatePortalInBody = () => {
const wrapperRef = useRef(null);
if (wrapperRef.current === null && typeof document !== 'undefined') {
const div = document.createElement('div');
wrapperRef.current = div;
}
useLayoutEffect(() => {
const wrapper = wrapperRef.current;
if (!wrapper || typeof document === 'undefined') {
return;
}
document.querySelector('.article-wrapper').appendChild(wrapper);
return () => {
document.querySelector('.article-wrapper').appendChild(wrapper);
};
}, []);
return children => wrapperRef.current && ReactDOM.createPortal(children, wrapperRef.current);
};
function Demo(props = {}) {
const [toast, contextHolder] = Toast.useToast();
const createBodyPortal = useCreatePortalInBody();
const config = {
duration: 3,
title: 'This is a success message',
content: <ReachableContext.Consumer>{name => `ReachableContext: ${name}`}</ReachableContext.Consumer>,
};
return (
<ReachableContext.Provider value="Light">
<div>
<Button
onClick={() => {
toast.success(config);
}}
>
Hook Toast
</Button>
</div>
{createBodyPortal(
<div style={{ position: 'fixed', top: 0, left: '50%', zIndex: 10000 }}>{contextHolder}</div>
)}
</ReachableContext.Provider>
);
}
render(Demo);
组件提供的静态方法,使用方式和参数如下:展示:可以直接传入 options 对象或 string,返回值为toastId:const toastId = Toast.info({ /*...options*/ })
Toast.info(options || string)Toast.error(options || string)Toast.warning(options || string)Toast.success(options || string)手动关闭 ( toastId 为展示方法的返回值)

ToastFactory.create(config) => Toast
如果您的应用中需要使用不同 config 的 Toast,可以使用 ToastFactory.create(config)创建新的 Toast (>= 1.23):
import React from 'react';
import { Button } from '@douyinfe/semi-ui';
function Demo() {
const ToastInCustomContainer = ToastFactory.create({
getPopupContainer: () => document.getElementById('custom-toast-container'),
});
return (
<div>
<Button onClick={() => Toast.info('Toast')}>Default Toast</Button>
<br />
<br />
<Button onClick={() => ToastInCustomContainer.info('Toast in some container')}>
Toast in custom container
</Button>
<div id="custom-toast-container">custom container</div>
</div>
);
}
render(Demo);
全局销毁 ( >= 0.25.0 ):
Toast.destroyAll()HookToast ( >= 1.2.0 ):
Toast.useToast()info, success, warning, error, close。
