| ## API |
| |
| Common props ref:[Common props](/docs/react/common-props) |
| |
| This component provides some static methods, with usage and arguments as following: |
| |
| - `message.success(content, [duration], onClose)` |
| - `message.error(content, [duration], onClose)` |
| - `message.info(content, [duration], onClose)` |
| - `message.warning(content, [duration], onClose)` |
| - `message.loading(content, [duration], onClose)` |
| |
| | Argument | Description | Type | Default | |
| | --- | --- | --- | --- | |
| | content | The content of the message | ReactNode \| config | - | |
| | duration | Time(seconds) before auto-dismiss, don't dismiss if set to 0 | number | 1.5 | |
| | onClose | Specify a function that will be called when the message is closed | function | - | |
| |
| `afterClose` can be called in thenable interface: |
| |
| - `message[level](content, [duration]).then(afterClose)` |
| - `message[level](content, [duration], onClose).then(afterClose)` |
| |
| where `level` refers one static methods of `message`. The result of `then` method will be a Promise. |
| |
| Supports passing parameters wrapped in an object: |
| |
| - `message.open(config)` |
| - `message.success(config)` |
| - `message.error(config)` |
| - `message.info(config)` |
| - `message.warning(config)` |
| - `message.loading(config)` |
| |
| The properties of config are as follows: |
| |
| | Property | Description | Type | Default | |
| | --- | --- | --- | --- | |
| | className | Customized CSS class | string | - | |
| | content | The content of the message | ReactNode | - | |
| | duration | Time(seconds) before auto-dismiss, don't dismiss if set to 0 | number | 3 | |
| | icon | Customized Icon | ReactNode | - | |
| | key | The unique identifier of the Message | string \| number | - | |
| | style | Customized inline style | [CSSProperties](https://github.com/DefinitelyTyped/DefinitelyTyped/blob/e434515761b36830c3e58a970abf5186f005adac/types/react/index.d.ts#L794) | - | |
| | onClick | Specify a function that will be called when the message is clicked | function | - | |
| | onClose | Specify a function that will be called when the message is closed | function | - | |
| |
| ### Global static methods |
| |
| Methods for global configuration and destruction are also provided: |
| |
| - `message.config(options)` |
| - `message.destroy()` |
| |
| > use `message.destroy(key)` to remove a message. |
| |
| #### message.config |
| |
| > When you use `ConfigProvider` for global configuration, the system will automatically start RTL mode by default.(4.3.0+) |
| > |
| > When you want to use it alone, you can start the RTL mode through the following settings. |
| |
| ```js |
| message.config({ |
| top: 100, |
| duration: 2, |
| maxCount: 3, |
| rtl: true, |
| prefixCls: 'my-message', |
| }); |
| ``` |
| |
| | Argument | Description | Type | Default | Version | |
| | --- | --- | --- | --- | --- | |
| | duration | Time before auto-dismiss, in seconds | number | 3 | | |
| | getContainer | Return the mount node for Message, but still display at fullScreen | () => HTMLElement | () => document.body | | |
| | maxCount | Max message show, drop oldest if exceed limit | number | - | | |
| | prefixCls | The prefix className of message node | string | `ant-message` | 4.5.0 | |
| | rtl | Whether to enable RTL mode | boolean | false | | |
| | top | Distance from top | string \| number | 8 | | |

| ## FAQ |
| |
| ### Why I can not access context, redux, ConfigProvider `locale/prefixCls/theme` in message? |
| |
| antd will dynamic create React instance by `ReactDOM.render` when call message methods. Whose context is different with origin code located context. |
| |
| When you need context info (like ConfigProvider context), you can use `message.useMessage` to get `api` instance and `contextHolder` node. And put it in your children: |
| |
| ```tsx |
| const [api, contextHolder] = message.useMessage(); |
| |
| return ( |
| <Context1.Provider value="Ant"> |
| {/* contextHolder is inside Context1 which means api will get value of Context1 */} |
| {contextHolder} |
| <Context2.Provider value="Design"> |
| {/* contextHolder is outside Context2 which means api will **not** get value of Context2 */} |
| </Context2.Provider> |
| </Context1.Provider> |
| ); |
| ``` |
| |
| **Note:** You must insert `contextHolder` into your children with hooks. You can use origin method if you do not need context connection. |
| |
| > [App Package Component](/components/app) can be used to simplify the problem of `useMessage` and other methods that need to manually implant contextHolder. |
| |
| ### How to set static methods prefixCls ? |
| |
| You can config with [`ConfigProvider.config`](/components/config-provider#configproviderconfig-4130) |
