如何使用ref获取物料界面对话框的高度？

import React, { createRef } from 'react';

class Dialog extends React.Component {
  dialogRef = createRef();

  // ...
}

class Dialog extends React.Component {
  // ...

  render() {
    return (
      <div ref={this.dialogRef}>
        {/* 对话框内容 */}
      </div>
    );
  }
}

class Dialog extends React.Component {
  // ...

  getHeight() {
    const dialogElement = this.dialogRef.current;
    const height = dialogElement.offsetHeight;
    return height;
  }
}
