Javascript - copy text string on click

Question

I spent a good 20 min searching online for this, but couldn't find it. What I want is to to be able to copy a text string on click without a button. The text string will be inside a "span" class.

1. User hovers over text string
2. User clicks text string
3. Text string is copied to clipboard

Any help would be greatly appreciated. Thanks!

Answer 1

You can attach copy event to <span> element, use document.execCommand("copy") within event handler, set event.clipboardData to span .textContent with .setData() method of event.clipboardData

const span = document.querySelector("span");

span.onclick = function() {
  document.execCommand("copy");
}

span.addEventListener("copy", function(event) {
  event.preventDefault();
  if (event.clipboardData) {
    event.clipboardData.setData("text/plain", span.textContent);
    console.log(event.clipboardData.getData("text"))
  }
});

<span>text</span>

Answer 2

Try this .document.execCommand('copy')

1. click the element and copy the text and post with tmp input element
2. Then copy the text from this input

function copy(that){
var inp =document.createElement('input');
document.body.appendChild(inp)
inp.value =that.textContent
inp.select();
document.execCommand('copy',false);
inp.remove();
}

<p onclick="copy(this)">hello man</p>

Along with copying the text , you also have to make sure that any previously selected component remains selected after copying to clipboard.

Here's the full code :

const copyToClipboard = str => {
  const el = document.createElement('textarea');  // Create a <textarea> element
  el.value = str;                                 // Set its value to the string that you want copied
  el.setAttribute('readonly', '');                // Make it readonly to be tamper-proof
  el.style.position = 'absolute';                 
  el.style.left = '-9999px';                      // Move outside the screen to make it invisible
  document.body.appendChild(el);                  // Append the <textarea> element to the HTML document
  const selected =            
    document.getSelection().rangeCount > 0        // Check if there is any content selected previously
      ? document.getSelection().getRangeAt(0)     // Store selection if found
      : false;                                    // Mark as false to know no selection existed before
  el.select();                                    // Select the <textarea> content
  document.execCommand('copy');                   // Copy - only works as a result of a user action (e.g. click events)
  document.body.removeChild(el);                  // Remove the <textarea> element
  if (selected) {                                 // If a selection existed before copying
    document.getSelection().removeAllRanges();    // Unselect everything on the HTML document
    document.getSelection().addRange(selected);   // Restore the original selection
  }
};

HTML:

<button type='button' id='btn'>Copy</button>

JS

document.querySelect('#btn').addEventListener('click', function() {
   copyToClipboard('copy this text');
});

JS / Function:

function copyToClipboard(text) {
    var selected = false;
    var el = document.createElement('textarea');
    el.value = text;
    el.setAttribute('readonly', '');
    el.style.position = 'absolute';
    el.style.left = '-9999px';
    document.body.appendChild(el);
    if (document.getSelection().rangeCount > 0) {
        selected = document.getSelection().getRangeAt(0)
    }
    el.select();
    document.execCommand('copy');
    document.body.removeChild(el);
    if (selected) {
        document.getSelection().removeAllRanges();
        document.getSelection().addRange(selected);
    }
};
