这是我前段时间写的代码，可能有用。 你要用这条线=> this。State = {checked: false, checke2: true};

class Componente extends React.Component {
  constructor(props) {
    super(props);

    this.state = { checked: false, checked2: true};
    this.handleChange = this.handleChange.bind(this);
    this.handleChange2 = this.handleChange2.bind(this);

  }  

  handleChange() {
    this.setState({
        checked: !this.state.checked      
    })
  }

  handleChange2() {
    this.setState({
        checked2: !this.state.checked2      
    })
  }

  render() {
    const togglecheck1 = this.state.checked ? 'hidden-check1' : '';
    const togglecheck2 = this.state.checked2 ? 'hidden-check2' : '';

    return <div>
        <div>
        <label>Check 1</label>
        <input type="checkbox" id="chk1"className="chk11" checked={ this.state.checked } onChange={ this.handleChange } />
        <label>Check 2</label>
        <input type="checkbox" id="chk2" className="chk22" checked={ this.state.checked2 } onChange={ this.handleChange2 } />
      </div>

      <div className={ togglecheck1 }>show hide div with check 1</div>
      <div className={ togglecheck2 }>show hide div with check 2</div>

    </div>;
  }
}

ReactDOM.render(
  <Componente />,
  document.getElementById('container')
);

CSS

.hidden-check1 {
  display: none;  
  }

.hidden-check2 {
  visibility: hidden;
}

HTML

  <div id="container">
      <!-- This element's contents will be replaced with your component. -->
  </div>

它的工作

<input type="checkbox" value={props.key} defaultChecked={props.checked} ref={props.key} onChange={this.checkboxHandler} />

函数初始化它

{this.viewCheckbox({ key: 'yourKey', text: 'yourText', checked: this.state.yourKey })}

你可以使用一个状态变量"enableSwitch"和一个函数"handleSwitch"来处理你默认的选中Switch:

<div class="custom-control custom-switch">
    <input type="checkbox" class="custom-control-input" id="switchId" checked={this.state.enableSwitch} onClick={this.handleSwitch}/>
    <label class="custom-control-label" for="switchId">switch text</label>
</div>

下面是一个函数，如果用户点击开关，它会反转变量:

handleSwitch = (e) => {
   this.setState({ enableSwitch: !this.state.enableSwitch });
}

我知道这是对一个老问题的晚回复，但这个简短的解决方案可能会帮助其他用户。

要与复选框交互，您需要在更改复选框后更新复选框的状态。你可以使用defaultChecked来设置默认值。

一个例子:

<input type="checkbox" defaultChecked={this.state.chkbox} onChange={this.handleChangeChk} />

<div className="display__lbl_input">
              <input
                type="checkbox"
                onChange={this.handleChangeFilGasoil}
                value="Filter Gasoil"
                name="Filter Gasoil"
                id=""
              />
              <label htmlFor="">Filter Gasoil</label>
            </div>

handleChangeFilGasoil = (e) => {
    if(e.target.checked){
        this.setState({
            checkedBoxFG:e.target.value
        })
        console.log(this.state.checkedBoxFG)
    }
    else{
     this.setState({
        checkedBoxFG : ''
     })
     console.log(this.state.checkedBoxFG)
    }
  };
