|
||
|
||
## API
|
||
|
||
This components 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.warn(content, [duration], onClose)` // alias of warning
|
||
- `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 | - |

|
||
- `message[level](content, [duration], onClose).then(afterClose)`
|
||
|

where `level` refers one static methods of `message`. The result of `then` method will be a Promise.

- `message.error(config)`
|
||
- `message.info(config)`
|
||
- `message.warning(config)`
|
||
- `message.warn(config)` // alias of warning
|
||
- `message.loading(config)`

### 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,

## FAQ
|
||
|
||
### Why I can not access context, redux, ConfigProvider `locale/prefixCls` 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.
|
||
|
||
### How to set static methods prefixCls ？
|
||
|
||
You can config with [`ConfigProvider.config`](/components/config-provider/#ConfigProvider.config()-4.13.0+)
