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>

对于那些试图从DIV而不是文本字段中进行选择的人，下面是代码。代码是不言自明的，但如果你想了解更多信息，请在这里评论:

     import React from 'react';
     ....

    //set ref to your div
          setRef = (ref) => {
            // debugger; //eslint-disable-line
            this.dialogRef = ref;
          };

          createMarkeup = content => ({
            __html: content,
          });

    //following function select and copy data to the clipboard from the selected Div. 
   //Please note that it is only tested in chrome but compatibility for other browsers can be easily done

          copyDataToClipboard = () => {
            try {
              const range = document.createRange();
              const selection = window.getSelection();
              range.selectNodeContents(this.dialogRef);
              selection.removeAllRanges();
              selection.addRange(range);
              document.execCommand('copy');
              this.showNotification('Macro copied successfully.', 'info');
              this.props.closeMacroWindow();
            } catch (err) {
              // console.log(err); //eslint-disable-line
              //alert('Macro copy failed.');
            }
          };

              render() {
                    return (
                        <div
                          id="macroDiv"
                          ref={(el) => {
                            this.dialogRef = el;
                          }}
                          // className={classes.paper}
                          dangerouslySetInnerHTML={this.createMarkeup(this.props.content)}
                        />
                    );
            }

最简单的方法是使用react-copy-to-clipboard npm包。

您可以使用以下命令安装它

npm install --save react react-copy-to-clipboard

请按照以下方式使用它。

const App = React.createClass({
  getInitialState() {
    return {value: '', copied: false};
  },


  onChange({target: {value}}) {
    this.setState({value, copied: false});
  },


  onCopy() {
    this.setState({copied: true});
  },


  render() {
    return (
      <div>

          <input value={this.state.value} size={10} onChange={this.onChange} />

        <CopyToClipboard text={this.state.value} onCopy={this.onCopy}>
          <button>Copy</button>
        </CopyToClipboard>

                <div>
        {this.state.copied ? <span >Copied.</span> : null}
                </div>
        <br />

        <input type="text" />

      </div>
    );
  }
});

ReactDOM.render(<App />, document.getElementById('container'));

这是一把移动小提琴。

我采取了和上面一些非常相似的方法，但我认为它更具体一些。在这里，父组件将作为道具传递url(或任何您想要的文本)。

import * as React from 'react'

export const CopyButton = ({ url }: any) => {
  const copyToClipboard = () => {
    const textField = document.createElement('textarea');
    textField.innerText = url;
    document.body.appendChild(textField);
    textField.select();
    document.execCommand('copy');
    textField.remove();
  };

  return (
    <button onClick={copyToClipboard}>
      Copy
    </button>
  );
};

你可以做到这一点，而不需要一个外部库，例如:在一个按钮

<button 
  onClick={() =>  navigator.clipboard.writeText('Copy this text to clipboard')}
>
  Copy
</button>

对于ie11和更老的浏览器，你可能需要稍微改变一下代码，这里有一个例子:

<button 
  onClick={() =>  window.clipboardData.setData("Text", 'Copy this text to clipboard')}>
 Copy
</button>

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
