Switch 开关

表示两种相互对立的状态间的切换，多用于触发「开/关」。选中时的内容支持响应式。

import { Switch } from 'uiw';
// or
import Switch from '@uiw/react-switch';

基本用法

import React from 'react';
import { Switch } from 'uiw';

export default function Demo() {
  return (
    <div>
      <Switch checked style={{ marginRight: 10 }} />
      <Switch style={{ marginRight: 10 }} />
      <Switch data-checked="开" data-unchecked="关">电源</Switch>
    </div>
  );
}

Form 中使用 Switch

import React from 'react';
import { Form, Switch, Row, Col, Button, Notify } from 'uiw';

export default function Demo() {
  return (
    <Form
      onChange={({ initial, current }) => { }}
      resetOnSubmit={false}
      onSubmitError={(error) => error && error.filed ? { ...error.filed } : null}
      onSubmit={({initial, current}) => {
        console.log('switch::', initial, current)
        const ErrObj = {};
        if(Object.keys(ErrObj).length > 0) {
          const err = new Error();
          err.filed = ErrObj;
          throw err;
        }
      }}
      fields={{
        switch: {
          checked: true,
          initialValue: true,
          label: '请输入内容',
          help: '必选选项！',
          validator: value => !value ? '必填选项！' : null,
          children: <Switch style={{ maxWidth: 200 }} />,
        },
      }}
    >
      {({ fields, state, canSubmit }) => {
        return (
          <div>
            <Row>
              <Col>{fields.switch}</Col>
            </Row>
            <Row>
              <Col>
                <Button disabled={!canSubmit()} type="primary" htmlType="submit">提交</Button>
              </Col>
            </Row>
            <Row>
              <Col>
                <pre style={{ padding: 10, marginTop: 10 }}>
                  {JSON.stringify(state.current, null, 2)}
                </pre>
              </Col>
            </Row>
          </div>
        );
      }}
    </Form>
  );
}

设置文字

import React from 'react';
import { Switch } from 'uiw';

export default function Demo() {
  return (
    <div>
      <Switch
        data-checked="开"
        data-unchecked="关"
        onChange={(e) => {
          console.log('e', e.target.checked);
        }}
        style={{ marginRight: 10 }}
      />
    </div>
  );
}

禁用状态

import React from 'react';
import { Switch } from 'uiw';

export default function Demo() {
  return (
    <div>
      <Switch disabled checked style={{ marginRight: 10 }} />
      <Switch disabled style={{ marginRight: 10 }} />
      <Switch disabled data-checked="开" data-unchecked="关">电源</Switch>
    </div>
  );
}

尺寸

import React from 'react';
import { Switch } from 'uiw';

export default function Demo() {
  return (
    <div>
      <Switch size="large" style={{ marginRight: 10 }} data-checked="开" data-unchecked="关" />
      <Switch size="large" checked style={{ marginRight: 10 }} />
      <Switch style={{ marginRight: 10 }} />
      <Switch style={{ marginRight: 10 }} data-checked="开" data-unchecked="关" />
      <Switch size="small" data-checked="开" data-unchecked="关">电源</Switch>
    </div>
  );
}

控制组件

通过 checked 属性改变 Switch 组件状态。

import React from 'react';
import { Switch, Button } from 'uiw';

class Demo extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      checked: true
    }
  }
  onChange(e) {
    console.log('~~~:::');
    this.setState({ checked: e.target.checked });
  }
  render() {
    return (
      <div style={{ backgroundColor: '#fff', margin: -15, padding: 15, borderRadius: '5px 5px 0 0' }}>
        <Switch onChange={this.onChange.bind(this)} checked={this.state.checked} style={{ marginRight: 10 }} />
        <Button
          size="small"
          type="primary"
          onClick={() => {
            this.setState({ checked: !this.state.checked });
          }}
        >
          点击按钮改变 Switch 状态
        </Button>
      </div>
    )
  }
}
export default Demo;
