Alert API

想要学习更多组件属性和 CSS API，可以查阅 React Alert 组件的 API 文档。

导入

import Alert from '@mui/material/Alert';
// 或
import { Alert } from '@mui/material';
You can learn about the difference by reading this guide on minimizing bundle size.

组件名称

The name MuiAlert can be used when providing default props or style overrides in the theme.

属性

Paper 组件的属性也是可用的。

名称类型默认值描述
actionnode
The action to display. It renders after the message, at the end of the alert.
childrennode
The content of the component.
classesobject
Override or extend the styles applied to the component. See CSS API below for more details.
closeTextstring'Close'
Override the default label for the close popup icon button.
For localization purposes, you can use the provided translations.
color'error'
| 'info'
| 'success'
| 'warning'
| string
The color of the component. Unless provided, the value is taken from the severity prop. It supports both default and custom theme colors, which can be added as shown in the palette customization guide.
iconnode
Override the icon displayed before the children. Unless provided, the icon is mapped to the value of the severity prop.
iconMapping{ error?: node, info?: node, success?: node, warning?: node }
The component maps the severity prop to a range of different icons, for instance success to <SuccessOutlined>. If you wish to change this mapping, you can provide your own. Alternatively, you can use the icon prop to override the icon displayed.
onClosefunc
Callback fired when the component requests to be closed. When provided and no action prop is set, a close icon button is displayed that triggers the callback when clicked.

Signature:
function(event: object) => void
event: The event source of the callback.
rolestring'alert'
The ARIA role attribute of the element.
severity'error'
