我个人认为没有必要为此建立一个图书馆。看看http://caniuse.com/#feat=clipboard，它现在得到了相当广泛的支持，但是你仍然可以做一些事情，比如检查当前客户端是否存在该功能，如果它不存在，就隐藏复制按钮。

import React from 'react';

class CopyExample extends React.Component {

  constructor(props) {
    super(props);

    this.state = { copySuccess: '' }
  }

  copyToClipboard = (e) => {
    this.textArea.select();
    document.execCommand('copy');
    // This is just personal preference.
    // I prefer to not show the whole text area selected.
    e.target.focus();
    this.setState({ copySuccess: 'Copied!' });
  };

  render() {
    return (
      <div>
        {
         /* Logical shortcut for only displaying the 
            button if the copy command exists */
         document.queryCommandSupported('copy') &&
          <div>
            <button onClick={this.copyToClipboard}>Copy</button> 
            {this.state.copySuccess}
          </div>
        }
        <form>
          <textarea
            ref={(textarea) => this.textArea = textarea}
            value='Some text to copy'
          />
        </form>
      </div>
    );
  }

}
    
export default CopyExample;

更新:在React 16.7.0-alpha.0中使用React hook重写

import React, { useRef, useState } from 'react';

export default function CopyExample() {

  const [copySuccess, setCopySuccess] = useState('');
  const textAreaRef = useRef(null);

  function copyToClipboard(e) {
    textAreaRef.current.select();
    document.execCommand('copy');
    // This is just personal preference.
    // I prefer to not show the whole text area selected.
    e.target.focus();
    setCopySuccess('Copied!');
  };

  return (
    <div>
      {
       /* Logical shortcut for only displaying the 
          button if the copy command exists */
       document.queryCommandSupported('copy') &&
        <div>
          <button onClick={copyToClipboard}>Copy</button> 
          {copySuccess}
        </div>
      }
      <form>
        <textarea
          ref={textAreaRef}
          value='Some text to copy'
        />
      </form>
    </div>
  );
}

make a componant as follows :- 

//react functional componant 

import React, { useState } from "react";

function CopyToClipboard(props) {
  const [copied, setCopied] = useState("copy");
  return (
    <div
      className="font-medium mr-4 text-green-700 cursor-pointer"
      onClick={() => {
        navigator.clipboard.writeText(props.text);
        setCopied("copied");
      }}>
      {copied}
    </div>
  );
}

export default CopyToClipboard;

//then use this componant anywhere

<CopyToClipboard text={"text you want to copy"}></CopyToClipboard>

//it will give a text saying "copy"`enter code here` and after clicking on that text, text provided with props will get copied
                    
                  

您可以使用useRef选择元素中的文本，然后将其复制到剪贴板

import React, { useRef } from "react";

const Comp = () => {
   const copyTxt = useRef();

   const handleCopyTxt = () => {
   let txtDiv = copyTxt.current;
      if (document.selection) {
        // IE
        var range = document.body.createTextRange();
        range.moveToElementText(txtDiv);
        range.select();
      } else if (window.getSelection) {
        // other browsers
        var range = document.createRange();
        range.selectNode(txtDiv);
        window.getSelection().removeAllRanges();
        window.getSelection().addRange(range);
      }
      document.execCommand("copy");
    }

    return ( <div ref={copyTxt} > some text to copied </div> )
}

如果希望从DIV而不是文本字段中进行选择，下面是代码。“代码”是需要复制的值

import React from 'react'
class CopyToClipboard extends React.Component {

  copyToClipboard(code) {
    var textField = document.createElement('textarea')
    textField.innerText = code
    document.body.appendChild(textField)
    textField.select()
    document.execCommand('copy')
    textField.remove()
  }
  render() {
    return (
      <div onClick={this.copyToClipboard.bind(this, code)}>
        {code}
      </div>

    )
  }
}

export default CopyToClipboard

import React, { Component } from 'react';

export default class CopyTextOnClick extends Component {
    copyText = () => {
        this.refs.input.select();

        document.execCommand('copy');

        return false;
    }

    render () {
        const { text } = this.state;

        return (
            <button onClick={ this.copyText }>
                { text }

                <input
                    ref="input"
                    type="text"
                    defaultValue={ text }
                    style={{ position: 'fixed', top: '-1000px' }} />
            </button>
        )
    }
}

react钩子的最佳解决方案，不需要外部库

import React, { useState } from 'react'; const MyComponent = () => { const [copySuccess, setCopySuccess] = useState(''); // your function to copy here const copyToClipBoard = async copyMe => { try { await navigator.clipboard.writeText(copyMe); setCopySuccess('Copied!'); } catch (err) { setCopySuccess('Failed to copy!'); } }; return ( <div> <Button onClick={() => copyToClipBoard('some text to copy')}> Click here to copy </Button> // after copying see the message here {copySuccess} </div> ) }
