轻提示

在不中断主要任务的情况下展示短暂反馈。

本指南覆盖默认 Emotion 环境的 Material UI Core；扩展包与额外示例按清单单独标注。

使用场景与业务边界

计时器只请求关闭，宿主须更新 open；通知不实现队列、撤销或后端成功判定。

原生组成与范围

Snackbar, SnackbarContent

保持 Material UI 原生组合与类型，不替换为 JGuang／Base UI／Radix 同名 API。示例条目不是额外组件。

原生安装与初始化

npm install @mui/material@9.4.0 @emotion/react@11.14.0 @emotion/styled@11.14.1

采用原生 npm 包与 Emotion，不提供虚构的 JGuang UI Registry 地址。将示例放在原生 ThemeProvider 内，按项目选择 CssBaseline 或 ScopedCssBaseline。先检查 React、现有 Provider、锁文件与 SSR 配置；不要覆盖用户文件或忽略 peer 冲突。本批实际验收 React 19.2.8；React 18 及以下须匹配 react-is。完整初始化规则见随附的双语 setup 文档。

关键原生参数

仅解释本指南选出的关键参数，不是平铺的通用 API。原生继承来源、slot 结构、可空值与泛型仍按固定源码保留。

可运行原生示例

下列机器键只选择示例入口，不会作为通用 variant 属性传入每个组件。原生示例 JSX 与数据保持上游原文；JGuang 编写的验收示例明确标注。

真实使用示例

固定版本的未修改原生示例；复制时同时保留所需的局部辅助文件。

import * as React from 'react';
import Button from '@mui/material/Button';
import Snackbar, { SnackbarCloseReason } from '@mui/material/Snackbar';
import IconButton from '@mui/material/IconButton';
import CloseIcon from '@mui/icons-material/Close';

export default function SimpleSnackbar() {
  const [open, setOpen] = React.useState(false);

  const handleClick = () => {
    setOpen(true);
  };

  const handleClose = (
    event: React.SyntheticEvent | Event,
    reason?: SnackbarCloseReason,
  ) => {
    if (reason === 'clickaway') {
      return;
    }

    setOpen(false);
  };

  const action = (
    <React.Fragment>
      <Button color="secondary" size="small" onClick={handleClose}>
        UNDO
      </Button>
      <IconButton
        size="small"
        aria-label="close"
        color="inherit"
        onClick={handleClose}
      >
        <CloseIcon fontSize="small" />
      </IconButton>
    </React.Fragment>
  );

  return (
    <div>
      <Button onClick={handleClick}>Open Snackbar</Button>
      <Snackbar
        open={open}
        autoHideDuration={6000}
        onClose={handleClose}
        message="Note archived"
        action={action}
      />
    </div>
  );
}

示例依赖边界

react, @mui/material/Button, @mui/material/Snackbar, @mui/material/IconButton, @mui/icons-material/Close, @mui/material/Grid, @mui/material/Box, @mui/material/Stack, @mui/material/SnackbarContent, @mui/material/Fade, @mui/material/Slide, @mui/material/Grow, @mui/material/transitions, @mui/material/Alert, @mui/material/AppBar, @mui/material/CssBaseline, @mui/material/GlobalStyles, @mui/material/Toolbar, @mui/icons-material/Menu, @mui/material/Typography, @mui/material/Fab, @mui/icons-material/Add

直接导入 Icons／System／Utils 的示例需要匹配 9.4.0 包。局部数据与辅助文件属于示例闭包，不是额外组件。远程图片和模拟操作不提供后端。

固定上游 API 元数据参考

以下表格保留上游元数据，不是重新推断的通用类型体系。条件泛型、继承属性与回调细节以以下源码声明为准。主题默认配置可能覆盖元数据默认值。

Snackbar

import Snackbar from '@mui/material/Snackbar';
import { Snackbar } from '@mui/material';

SnackbarContent

import SnackbarContent from '@mui/material/SnackbarContent';
import { SnackbarContent } from '@mui/material';

原生继承: Paper. 父级与 DOM 属性未被伪造为本组件新属性。

原生源码声明

声明与 import 从固定源码提取，不平铺联合类型或外部继承。英文注释／类型属于原始源码参考，不代表上游正文已全文翻译。共享类型仍位于原生包中。

安装后验收

执行严格类型检查、生产构建和实际交互。检查键盘标签／焦点、原生支持的禁用／错误／只读语义、深浅色、窄屏和减少动画。按真实宿主数据检查回调，不把复制提示词当作安装完成。初始化工具还需检查服务端 HTML 与无告警水合。
