过渡动画

Mantine Core 的独立组件,请不要替换为 JGuang UI/Base UI 的同名 API。

安装

npm install @mantine/core@9.7.1 @mantine/hooks@9.7.1

入口引入 @mantine/core/styles.css,并在根组件使用 MantineProvider;通过 forceColorScheme 同步深浅色主题。

使用与验证

在左侧选择组件,在预览中操作它的状态;使用“查看代码”检查真实源码。安装后执行类型检查和构建,再验证键盘焦点、手机布局与深浅色主题。

版本与兼容性

固定的 Mantine Core 9.7.1 要求 React 和 React DOM 满足 ^19.2.0,并配套 @mantine/hooks@9.7.1。此条件来自实际 npm 包的 peerDependencies。React 18 或其他不兼容版本不能强行安装;先向项目负责人说明升级影响并确认方案,不使用 --force/--legacy-peer-deps 掩盖冲突。入口的原生 Provider 开启 theme.respectReducedMotion,并用 forceColorScheme 控制深浅色。

适用场景

为挂载内容应用过渡样式。

本地示例使用的原生参数

以下参数由本地、经过类型检查的 JSX 示例提取,按所属组件区分。不是全部属性清单;完整签名和继承关系见下方固定源码参考。

组件参数说明
Button.onClick本地点击处理,应按需替换为明确的业务操作。
Transition.mounted过渡内容是否应该存在。
Transition.transition原生过渡名称或配置。

交互与状态检查

当前场景:默认。切换支持的禁用、错误或只读场景后检查真实行为;无此原生状态的组件不会被强行添加统一属性。验证键盘焦点和退出方式,修改值后按原生回调签名连接业务状态。

业务接入边界

将渲染函数提供的 style 应用到动画元素。mounted 决定内容存在与否,过渡不会执行业务逻辑。

宿主配置

先安装固定版本 @mantine/core 和 @mantine/hooks,在入口引入 @mantine/core/styles.css,并使用 MantineProvider。示例的 theme 和 variant 是 JGuang 编写的宿主参数,不是所有原生组件都接受的统一 API;通过 forceColorScheme 同步应用主题。源码面板中的原生实现仅供阅读,使用 npm 导出,不要单独复制内部实现。此批只覆盖 Core,不包括日期、图表和表单扩展包。上游详细说明保留英文,不宣称全文中文化。

可运行用法

以下代码使用资源原生 API;不是把其他设计系统的同名组件替换进来。

import { useState } from 'react';
import * as M from '@mantine/core';
import '@mantine/core/styles.css';


function ComponentPreview({ variant = 'Default' }: { variant?: string }) {
const [open, setOpen] = useState(false);
const content = <M.Text>Build something beautiful / 构建美好的界面</M.Text>;
return <div><M.Button onClick={() => setOpen(!open)}>Toggle transition</M.Button><M.Transition mounted={open} transition="fade">{(styles) => <div style={styles}>{content}</div>}</M.Transition></div>;
}
export default function Example({ variant = 'Default', theme = 'light' }: { variant?: string; theme?: 'light' | 'dark' }) {
return <M.MantineProvider forceColorScheme={theme} theme={{ respectReducedMotion: true }}><ComponentPreview variant={variant} /></M.MantineProvider>;
}

可用状态与示例

默认

示例遵循 Mantine 原生 API。支持多状态的输入组件可将示例中的 variant 改为 Disabled、Invalid 或 Read only;这些只是示例标签,不是新增的组件属性。改造时保留组件要求的数据、受控值、store 和复合子组件结构。

Usage

The Transition component is designed to animate the presence of elements with fixed or absolute positioning, such as dropdowns, modals, or tooltips. Other Mantine components (like Modal and Tooltip) use Transition internally for their animations.

Note that the Transition component is not intended to be a comprehensive solution for all animations. It is a simple utility for animating the presence of elements with fixed or absolute positioning. If you need to implement more complex animations, consider using Motion, React Spring, or other dedicated animation libraries.

Example usage of the Transition component:

import { Transition } from '@mantine/core';

function Demo({ opened }: { opened: boolean }) {
  return (
    <Transition mounted={opened} transition="fade">
      {(styles) => <div style={styles}>Your modal</div>}
    </Transition>
  );
}

Premade transitions

Mantine includes several premade transitions:

To use one of them, set the transition property to one of these values:

import { Transition } from '@mantine/core';

function Demo({ opened }: { opened: boolean }) {
  return (
    <Transition
      mounted={opened}
      transition="fade"
      duration={400}
      timingFunction="ease"
    >
      {(styles) => <div style={styles}>Your modal</div>}
    </Transition>
  );
}

Custom transitions

You can create your own transition. transition is an object with 4 properties:

  • in – styles for mounted state
  • out – styles for unmounted state
  • common (optional) – styles for both mounted and unmounted states
  • transitionProperty – properties which participate in the transition

Enter and exit delay

Use the enterDelay and exitDelay props to delay the transition start. Values are in milliseconds:

Reduced motion

Transition respects the prefers-reduced-motion media query and your theme's respectReducedMotion setting. When reduced motion is preferred, all transitions complete instantly:

import { createTheme, MantineProvider, Transition } from '@mantine/core';

const theme = createTheme({
  respectReducedMotion: true, // default
});

function Demo() {
  return (
    <MantineProvider theme={theme}>
      <Transition mounted transition="fade" duration={400}>
        {(styles) => <div style={styles}>Content</div>}
      </Transition>
    </MantineProvider>
  );
}

This improves accessibility for users with vestibular disorders who may experience motion sickness from animations.

Lifecycle callbacks

Use lifecycle callbacks to perform actions at different stages of the transition:

  • onEnter - Called when enter transition starts
  • onEntered - Called when enter transition completes
  • onExit - Called when exit transition starts
  • onExited - Called when exit transition completes
import { Transition } from '@mantine/core';

function Demo() {
  return (
    <Transition
      mounted
      transition="fade"
      duration={200}
      onEnter={() => console.log('Enter started')}
      onEntered={() => console.log('Enter completed')}
      onExit={() => console.log('Exit started')}
      onExited={() => console.log('Exit completed')}
    >
      {(styles) => <div style={styles}>Content</div>}
    </Transition>
  );
}

Keep mounted

By default, the element is unmounted from the DOM when the transition is complete. Use keepMounted to keep the element mounted with display: none:

import { Transition } from '@mantine/core';

function Demo() {
  return (
    <Transition mounted={false} keepMounted transition="fade">
      {(styles) => <div style={styles}>Content</div>}
    </Transition>
  );
}

This is useful when you want to:

  • Preserve element state during hide/show
  • Avoid remounting overhead
  • Maintain focus/scroll position

源码参数参考

以下实现签名和类型从本地固定版本源码生成。保留可选属性、原生继承类型、联合分支和 never 限制;不会将其他设计系统的 API 混入。forwardRef 实现中的 ref 属于 React 引用,不是新增业务属性。此区域是原始类型参考,不是上游说明的全文翻译。

Transition({
  keepMounted,
  keepMountedMode = 'activity',
  transition = 'fade',
  duration = 250,
  exitDuration = duration,
  mounted,
  children,
  timingFunction = 'ease',
  onExit,
  onEntered,
  onEnter,
  onExited,
  enterDelay,
  exitDelay,
}: TransitionProps)
export interface TransitionProps {
  /** If set, the element is kept in the DOM when hidden. React 19 `Activity` is used to preserve state while the element is not visible. */
  keepMounted?: boolean;

  /**
   * Controls how the element is hidden when `keepMounted` is set:
   * `'activity'` - hidden with React 19 `Activity` component,
   * `'display-none'` - hidden with `display: none` styles
   * @default 'activity'
   */
  keepMountedMode?: 'activity' | 'display-none';

  /** Transition name or object */
  transition?: MantineTransition;

  /** Transition duration in ms @default 250 */
  duration?: number;

  /** Exit transition duration in ms @default 250 */
  exitDuration?: number;

  /** Transition timing function @default theme.transitionTimingFunction */
  timingFunction?: string;

  /** Determines whether component should be mounted to the DOM */
  mounted: boolean;

  /** Render function with transition styles argument */
  children: (styles: React.CSSProperties) => React.JSX.Element;

  /** Called when exit transition ends */
  onExited?: () => void;

  /** Called when exit transition starts */
  onExit?: () => void;

  /** Called when enter transition starts */
  onEnter?: () => void;

  /** Called when enter transition ends */
  onEntered?: () => void;

  /** Delay in ms before enter transition starts */
  enterDelay?: number;

  /** Delay in ms before exit transition starts */
  exitDelay?: number;
}

源码中的解构默认值

只列出直接写在参数或 props 解构中的默认表达式。条件表达式、运行时主题和其他计算值请结合源码;这里不是全部行为的默认值清单。

// Transition
keepMountedMode = 'activity'

// Transition
transition = 'fade'

// Transition
duration = 250

// Transition
exitDuration = duration

// Transition
timingFunction = 'ease'

原生与外部类型

以下外部类型仍由 React 或资源自身依赖定义,没有手工展开为虚构属性。实际可用类型以安装版本的 TypeScript 检查为准。

React.CSSProperties
