反应渲染按钮'x'时间

Question

我有一个开关按钮我想复制10次但是当我将按钮复制到newdiv时它不让我点击第二个按钮，我只能改变一个第一个按钮的状态。这是我的代码

class App extends Component {
handleSwitch = e => console.log(e.target.checked);
render() {
return (
<div>
<div>
<p className="title">source</p>
<label className="label">Button</label>2
<SwitchButton
onChange={this.handleSwitch}
title="SwitchButton"
data-name="vd"
/>
</div>
<div>
<label className="label">Button2</label>
<SwitchButton
onChange={this.handleSwitch}
title="SwitchButton2"
data-name="vd1"
/>
</div>
</div>
);
}
}

这里是我的现场演示:https://stackblitz.com/edit/react-ts-9n4lwa?file=index.tsx

你应该在每个SwitchButton中设置一个唯一的switchButtonID

import React, { Component } from 'react';
import { render } from 'react-dom';
import SwitchButton from './Hello';
import './style.scss';
class App extends Component {
handleSwitch = e => console.log(e.target.checked);
render() {
return (
<div>
<div>
<p className="title">Precursor source</p>
<label className="label">Ch1_PulsingValveActivationlnSw</label>
<SwitchButton
switchButtonID={1}
onChange={this.handleSwitch}
title="SwitchButton"
data-name="vd"
/>
</div>
<div>
<label className="label">Ch1_PulsingValveActivationlnSw</label>
<SwitchButton
switchButtonID={2}
onChange={this.handleSwitch}
title="SwitchButton2"
data-name="vd1"
/>
</div>
</div>
);
}
}
render(<App />, document.getElementById('root'));
