反应
changeTheme(e){
console.log(e.target.value);
}
class App extends React.Component {
render() {
return (

<div className="col-xs-12 text-center">
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Aliquam voluptates ut eaque, voluptatum veniam nostrum sequi numquam sint, excepturi amet unde quis, ipsum ducimus reprehenderit eligendi pariatur animi esse sed.</p>
<input

/>
<br/><br/>
</div>
</div>

解决方法:
终于找到解决办法
constructor(props){
super(props);
this.state = {color: '#3C454B'};
}
changeTheme(e){
this.setState({color: event.target.value});
document.documentElement.style.setProperty('--base',this.state.color);
}
class App extends React.Component {
render() {
return (
<div className="row">
<div className="col-xs-12 text-center">
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Aliquam voluptates ut eaque, voluptatum veniam nostrum sequi numquam sint, excepturi amet unde quis, ipsum ducimus reprehenderit eligendi pariatur animi esse sed.</p>
<input
className=""
type="color"
defaultValue={this.state.color}
onChange={(e) => this.handleColor(e)}
/>
<br/><br/>
</div>
</div>
);
}
}
ReactDOM.render(<App />, window.document.getElementById('myDiv'));
