请看看我的代码。我尝试限制给定无状态组件的重新渲染，但这样做发现 shouldComponentUpdate 从未被调用。我已经从 styledComponents 中删除了包装器（之前有人报道过这种情况），但仍然没有被调用。除此之外，可以写一篇关于这个函数的捕获的文章

import React from 'react';
import GoogleSearchForm from './RenderGoogleSearchForm.js';
import ButtonWithMessage from './ButtonWithMessage.js';
import styled from 'styled-components';

export default class RenderTableOverHead extends React.Component{

  constructor(props) {
    super(props);
  }

  shouldComponentUpdate(nextProps, nextState) {
    console.log('shoulItdUpdate');
    return false;
  }

  render(){
    console.log('render overhead');
    const wrapstyle = 'd-flex align-items-center justify-content-center border-none'

  const Button = {
    // lots of defined buttons
  }

  return(

    <div className = {wrapstyle}> 
      {!this.props.isHiddenReturnButton && <Button.ReturnToPreliminarySearch />}
      {!this.props.isHiddenWelcomeButton && <Button.Welcome />}
      {!this.props.isHiddenFailureMsg && <Button.SearchFailure />}
      {!this.props.isHiddenResultsMsg && <Button.SearchResults /> }
      {(this.props.isConnectionOK >0||this.props.isConnectionOK===undefined) && <Button.ConnectionError /> }
      {!this.props.isHiddenInputForm && <GoogleSearchForm  FetchBooks = {this.props.FetchBooks} /> }
      {!this.props.isHiddenFilterToggleButton && <Button.FilterShowPrompt />}
  </div>
)}}

根据要求 - 由父母这样调用：

import RenderTableOverHead from './components/RenderTableOverHead.js';

在它下面挤满了props以形成新的功能

  const Overhead = ()=>{return(  

      <RenderTableOverHead 

      isHiddenInputForm={ this.state.isHiddenInputForm}
      isHiddenWelcomeButton={this.state.isHiddenWelcomeButton}
      ShowGoogleSearch={this.handleWelcomeButtonClick}
      //SubmitInputDataToParentState={this.fetchBooks}
      FetchBooks ={this.fetchBooks}
      isHiddenResultsMsg={this.state.isHiddenResultsMsg}
      isHiddenFailureMsg={this.state.isHiddenFailureMsg}
      toggleFilterVisibility={this.toggleFilterVisibility}
      numberOfResults ={catalog.TotalNumberOfBooks}
      numberOfPages =/*{_.last(TableWithPageNumbers)}*/{catalog.NumberOfPages}
      currentPageNumber ={catalog.CurrentPageNumber}
      //currentPage ={this.Page}//tu podmieniony numer strony jest kosztem powyższego
      isConnectionOK={this.state.connectionStatus}
      //errorStatus ={this.state.errorStatus}
      //errorMessage ={this.state.errorMessage}
      //handleError={this.handleError}
      isHiddenReturnButton={this.state.isHiddenReturnButton}
      isHiddenFilterToggleButton={this.state.isHiddenFilterToggleButton}
      />


);}

并像这样返回（这里它命名为开销）

return(

        <div className='container'>
        <Overhead />
        <Pagination />
        {isDataLoaded && 
           <div className = {cardStyle}>
           <table className = {tableStyle}>
                <thead className = {tableHeaderStyle}>
                <Headline />     
                {Filtration}            
                </thead>
                <TableBody />     
       </table>
       </div>};
       </div>)
