How to Copy Text To Clipboard Using Javascript

1. document.execCopy

We can use document.execCopy which has widely browser support. One important to notice is that it is right now deprecated.

• Access is synchronous
• Text is read from the DOM and placed on the clipboard.
• Good browser support

function fallbackCopyTextToClipboard(text) {
  var textArea = document.createElement("textarea");
  textArea.value = text;

  // Avoid scrolling to bottom
  textArea.style.top = "0";
  textArea.style.left = "0";
  textArea.style.position = "fixed";

  document.body.appendChild(textArea);
  textArea.focus();
  textArea.select();

  try {
    var successful = document.execCommand('copy');
    var msg = successful ? 'successful' : 'unsuccessful';
    console.log('Fallback: Copying text command was ' + msg);
  } catch (err) {
    console.error('Fallback: Oops, unable to copy', err);
  }

  document.body.removeChild(textArea);
}

2. Navigator.clipboard.writeText

The Clipboard API adds to the Navigator interface the read-only clipboard property, which returns the Clipboard object used to read and write the clipboard's contents.

• writeText is used for writing contents to clipboard.
• Access is asynchronous and uses promises.
• Only supported on pages served over HTTPS.

navigator.clipboard.writeText(text).then(
  function() {
    console.log("Async: Copying to clipboard was successful!");
  },
  function(err) {
    console.error("Async: Could not copy text: ", err);
  }
);
