嗨，我一直被困在 React Function 中useState。我只是想学习 hooks 和 useState，但我什至费力寻找解决方案也没有任何进展。这是我的完整反应功能：

import React, { useState } from 'react';
import './MainPart.css';

function MainPart(props) {
  const [orderData_, setOrderData_] = useState(props.orderData);

  let topicData_ = props.topicData;
  let titleData_ = props.titleData;
  let infoData_ = props.infoData;

  return (
    <div className='MainPart'>
      <div className='mainWindow'>{getPics(orderData_)}</div>
      <div className='information'>
        <div className='moreNewsDivs'>
          <div className='moreNewsDiv1'>
            <h4>MORE NEWS</h4>
          </div>
          <div className='moreNewsDiv2'>
            <button
              className='previous-round'
              onClick={setOrderData_(previous(orderData_))}
            >
              &#8249;
            </button>
            &nbsp;&nbsp; &nbsp;&nbsp;
            <button href='/#' className='next-round'>
              &#8250;
            </button>
          </div>
        </div>
        <hr />
        <div className='topicDiv'>
          <h5 className='topicData'>{topicData_}</h5>
          <h5 className='titleData'>{titleData_}</h5>
          <h6 className='infoData'>{infoData_}</h6> …

这是与ejs一起使用的代码:

<iframe width="660" height="371" src="<%= revive.reviveVideo %>"></iframe>

哈巴狗相当于什么？试过这个,但它不起作用:

iframe(width='660', height='371', src='#{revive.reviveVideo}')

如果我将变量更改为实际路径,它就可以正常工作......这是变量语法的一个问题......
