React多页面跳转[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

const queryArray = (array, key, keyAlias = 'key') => {
  if (!(array instanceof Array)) {
    return null
  }
  let data;
  for (let item of array) {
    if (item[keyAlias] === key) {
      data = item;
      break
    }
  }
  if (data) {
    return data
  }
  return null
}

render () { const { app: { locationQuery } } = this.props; tolist.js const { 子页面数据 } = this.state; const { id } = locationQuery; ///获取当前页面地址栏的id const info = queryArray(子页面数据, parseInt(id), 'id'); ///根据id拿到当前页面id下面的数据存放到info console.log(info); let pagination = null; if (this.state.pages) { pagination = this.renderPagination(this.state.page, this.state.pages); } const Functionlist = () => { return ( <div> {info ? // 判断如果有此id 渲染一下内容 <div className={styles.center}> <h2>{info.title}</h2> <video src={info.url} controls="controls"></video> </div> : null} // 如果没有就渲染为空 </div> ) } return ( <DocumentTitle title="1234"> <div ref={node => this.node = node} className={styles.notice}> <div> <Functionlist /> </div> </div> </DocumentTitle> ) }

<Link to={"/video/tolist_1?id="+item.id}  key={index}>      two.js
      <li className={styles.li}></li>
</Link>

 {
    path:'/video/tolist',
    component:()=>import('../routes/video/tolist')     //文件夹 video 下面三个js   twolist.js&&&two.js /// video.js为单页面跳转页面
  },
