将p标签之间的文本复制到React中的剪贴板

Question

I am trying to create copy to Clipboard Component. Here is my code:

import React from 'react';
import logo from './logo.svg';
import './App.css';

class CopyClipboard extends React.Component {

  constructor(props) {
    super(props);

    this.state = { copySuccess: 'Copy to Clipboard!' }
  }

  copyToClipboard = (e) => {

    this.textContent.select();
    document.execCommand('copy');
    e.target.focus();
    this.setState({ copySuccess: 'Copied to Clipboard!' });
  };

  render() {
    return (
      <div class="positioning">
        {
           //if i need
        }

          <p onClick={this.copyToClipboard} ref={(c) => (this.textContent = c)}>yotam@gmail.com</p>
        <div class="success">{this.state.copySuccess}</div>
      </div>
    );
  }

}

export default CopyClipboard;

I get Parsing error: Unexpected token error. But if i use input tag then its work fine. Where i have done wrong?

Answer 1

For p tag, you can't use .select .

You need to use selectNode and addRange

Try something like this for the selection function

copyToClipboard = async e => {
  window.getSelection().removeAllRanges();
  var range = document.createRange();
  range.selectNode(this.textContent);
  window.getSelection().addRange(range);
  document.execCommand("copy");
  window.getSelection().removeAllRanges();
  this.setState({ copied: true });
};
