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> ) }

针对React开发者

 const preventCopyPasteBody = (state) => {
       document.addEventListener(state, (evt) => {
      if (evt.target.id === 'body') {
             evt.preventDefault();
           return false;
          }
        return false;
       }, false);
      }

 preventCopyPasteBody ("contextmenu")
 preventCopyPasteBody ("copy")
 preventCopyPasteBody ("paste")
 preventCopyPasteBody ("cut")

<Typography id="body" variant="body1"  component="div" className={classes.text} style={{ fontSize: fontSize }}>{story}</Typography>

您可以使用事件clipboardData收集方法e.clipboardData。setData(类型、内容)。

在我看来，这是实现在剪贴板内推送一些东西的最直接的方法，看看这个(我用它来修改数据，而本地复制动作):

...

handleCopy = (e) => {
    e.preventDefault();
    e.clipboardData.setData('text/plain', 'Hello, world!');
}

render = () =>
    <Component
        onCopy={this.handleCopy}
    />

干杯!

编辑:出于测试目的，我添加了代码依赖:https://codepen.io/dprzygodzki/pen/ZaJMKb

这是我的代码:

import React from 'react'

class CopyToClipboard extends React.Component {

  textArea: any

  copyClipBoard = () => {
    this.textArea.select()
    document.execCommand('copy')
  }

  render() {
    return (
      <>
        <input style={{display: 'none'}} value="TEXT TO COPY!!" type="text" ref={(textarea) => this.textArea = textarea}  />
        <div onClick={this.copyClipBoard}>
        CLICK
        </div>
      </>

    )
  }
}

export default CopyToClipboard

找到了最好的方法。我是说最快的方法:w3school

https://www.w3schools.com/howto/howto_js_copy_clipboard.asp

在react函数组件中。创建名为handleCopy的函数:

function handleCopy() {
  // get the input Element ID. Save the reference into copyText
  var copyText = document.getElementById("mail")
  // select() will select all data from this input field filled  
  copyText.select()
  copyText.setSelectionRange(0, 99999)
  // execCommand() works just fine except IE 8. as w3schools mention
  document.execCommand("copy")
  // alert the copied value from text input
  alert(`Email copied: ${copyText.value} `)
}

<>
              <input
                readOnly
                type="text"
                value="exemple@email.com"
                id="mail"
              />
              <button onClick={handleCopy}>Copy email</button>

</>

如果不使用React, w3schools也有一个很酷的方法来做到这一点，工具提示包括:https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_copy_clipboard2

如果使用React，一个很酷的想法是:使用Toastify提醒消息。 https://github.com/fkhadra/react-toastify这是一个很容易使用的库。 安装后，你可以更改这一行:

 alert(`Email copied: ${copyText.value} `)

比如:

toast.success(`Email Copied: ${copyText.value} `)

如果你想使用它，不要忘记安装toastify。导入ToastContainer，同时也导入css:

import { ToastContainer, toast } from "react-toastify"
import "react-toastify/dist/ReactToastify.css"

并将烤面包的容器放入里面返回。

import React from "react"

import { ToastContainer, toast } from "react-toastify"
import "react-toastify/dist/ReactToastify.css"


export default function Exemple() {
  function handleCopy() {
    var copyText = document.getElementById("mail")
    copyText.select()
    copyText.setSelectionRange(0, 99999)
    document.execCommand("copy")
    toast.success(`Hi! Now you can: ctrl+v: ${copyText.value} `)
  }

  return (
    <>
      <ToastContainer />
      <Container>
                <span>E-mail</span>
              <input
                readOnly
                type="text"
                value="myemail@exemple.com"
                id="mail"
              />
              <button onClick={handleCopy}>Copy Email</button>
      </Container>
    </>
  )
}

你也可以在函数组件或无状态组件中使用react钩子: PS:确保你通过npm/yarn使用这个命令安装useClippy: NPM安装使用clippy或 纱线添加使用夹头

import React from 'react';
import useClippy from 'use-clippy';

export default function YourComponent() {

// clipboard is the contents of the user's clipboard.
  // setClipboard('new value') wil set the contents of the user's clipboard.

  const [clipboard, setClipboard] = useClippy();

  return (
    <div>

      {/* Button that demonstrates reading the clipboard. */}
      <button
        onClick={() => {
          alert(`Your clipboard contains: ${clipboard}`);
        }}
      >
        Read my clipboard
      </button>

      {/* Button that demonstrates writing to the clipboard. */}
      <button
        onClick={() => {
          setClipboard(`Random number: ${Math.random()}`);
        }}
      >
        Copy something
      </button>
    </div>
  );
}
