如何在ReactJS中用换行符设置文本区域值

<textarea value={this.state.textareaValue} />

handleChange(event) {
  this.setState({ textareaValue: event.target.value });
}

<textarea value={this.state.textareaValue} onChange={this.handleChange} />

import React, { Component } from 'react';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      textareaValue: ''
    };
    this.handleChange = this.handleChange.bind(this);
  }

  handleChange(event) {
    this.setState({ textareaValue: event.target.value });
  }

  render() {
    return (
      <textarea value={this.state.textareaValue} onChange={this.handleChange} />
    );
  }
}

export default MyComponent;
