## 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 | - | |

### 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', |

## 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) |
