Switch

Switching Selector.

When To Use#

If you need to represent the switching between two states or on-off state.
The difference between Switch and Checkbox is that Switch will trigger a state change directly when you toggle it, while Checkbox is generally used for state marking, which should work in conjunction with submit operation.

Examples

The most basic usage.

TypeScript
JavaScript
import { Switch } from 'infrad';
import React from 'react';

const onChange = (checked: boolean) => {
  console.log(`switch to ${checked}`);
};

const App: React.FC = () => <Switch defaultChecked onChange={onChange} />;

export default App;

Text & icon

With text and icon.

TypeScript
JavaScript
import { CheckOutlined, CloseOutlined } from 'infra-design-icons';
import { Switch } from 'infrad';
import React from 'react';

const App: React.FC = () => (
  <>
    <Switch checkedChildren="开启" unCheckedChildren="关闭" defaultChecked />
    <br />
    <Switch checkedChildren="1" unCheckedChildren="0" />
    <br />
    <Switch
      checkedChildren={<CheckOutlined />}
      unCheckedChildren={<CloseOutlined />}
      defaultChecked
    />
  </>
);

export default App;

Mark a pending state of switch.

TypeScript
JavaScript
import { Switch } from 'infrad';
import React from 'react';

const App: React.FC = () => (
  <>
    <Switch loading defaultChecked />
    <br />
    <Switch size="small" loading />
  </>
);

export default App;

Disabled

Disabled state of Switch.

TypeScript
JavaScript
import { Button, Switch } from 'infrad';
import React, { useState } from 'react';

const App: React.FC = () => {
  const [disabled, setDisabled] = useState(true);

  const toggle = () => {
    setDisabled(!disabled);
  };

  return (
    <>
      <Switch disabled={disabled} defaultChecked />
      <br />
      <Button type="primary" onClick={toggle}>
        Toggle disabled
      </Button>
    </>
  );
};

export default App;

Two sizes

size="small" represents a small sized switch.

TypeScript
JavaScript
import { Switch } from 'infrad';
import React from 'react';

const App: React.FC = () => (
  <>
    <Switch defaultChecked />
    <br />
    <Switch size="small" defaultChecked />
  </>
);

export default App;
