Message
Display global messages as feedback in response to user operations.
When To Use#
To provide feedback such as success, warning, error etc.
A message is displayed at top and center and will be dismissed automatically, as a non-interrupting light-weighted prompt.
Examples
import { Button, message } from 'infrad';
import React from 'react';
const info = () => {
message.info('This is a normal message');
};
const App: React.FC = () => (
<Button type="primary" onClick={info}>
Display normal message
</Button>
);
export default App;
import { Button, message } from 'infrad';
import React from 'react';
const success = () => {
message.success('This is a prompt message for success, and it will disappear in 10 seconds', 10);
};
const App: React.FC = () => <Button onClick={success}>Customized display duration</Button>;
export default App;
import { Button, message } from 'infrad';
import React from 'react';
const success = () => {
message
.loading('Action in progress..', 2.5)
.then(() => message.success('Loading finished', 2.5))
.then(() => message.info('Loading finished is finished', 2.5));
};
const App: React.FC = () => <Button onClick={success}>Display sequential messages</Button>;
export default App;
import { Button, message } from 'infrad';
import React from 'react';
const success = () => {
message.success({
content: 'This is a prompt message with custom className and style',
className: 'custom-class',
style: {
marginTop: '20vh',
},
});
};
const App: React.FC = () => <Button onClick={success}>Customized style</Button>;
export default App;
import { Button, message, Space } from 'infrad';
import React from 'react';
const success = () => {
message.success('This is a success message');
};
const error = () => {
message.error('This is an error message');
};
const warning = () => {
message.warning('This is a warning message');
};
const App: React.FC = () => (
<Space>
<Button onClick={success}>Success</Button>
<Button onClick={error}>Error</Button>
<Button onClick={warning}>Warning</Button>
</Space>
);
export default App;
import { Button, message } from 'infrad';
import React from 'react';
const success = () => {
const hide = message.loading('Action in progress..', 0);
// Dismiss manually and asynchronously
setTimeout(hide, 2500);
};
const App: React.FC = () => <Button onClick={success}>Display a loading indicator</Button>;
export default App;
import { Button, message } from 'infrad';
import React from 'react';
const key = 'updatable';
const openMessage = () => {
message.loading({ content: 'Loading...', key });
setTimeout(() => {
message.success({ content: 'Loaded!', key, duration: 2 });
}, 1000);
};
const App: React.FC = () => (
<Button type="primary" onClick={openMessage}>
Open the message box
</Button>
);
export default App;
import { Button, message } from 'infrad';
import React from 'react';
const Context = React.createContext({ name: 'Default' });
const App: React.FC = () => {
const [messageApi, contextHolder] = message.useMessage();
const info = () => {
messageApi.open({
type: 'info',
content: <Context.Consumer>{({ name }) => `Hello, ${name}!`}</Context.Consumer>,
duration: 1,
});
};
return (
<Context.Provider value={{ name: 'Infra Design' }}>
{contextHolder}
<Button type="primary" onClick={info}>
Display normal message
</Button>
</Context.Provider>
);
};
export default App;
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 warningmessage.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.warn(config)
// alias of warningmessage.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 | - |
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.
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 | () => 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 | number | 8 |
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:
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
