   <!-- The text field -->
  <input type="text" value="Hello World" id="myInput">
  
  <!-- The button used to copy the text -->
  <button onclick="myFunction()">Copy text</button> 
  
  function myFunction() {
    /* Get the text field */
    var copyText = document.getElementById("myInput");
  
    /* Select the text field */
    copyText.select();
    copyText.setSelectionRange(0, 99999); /* For mobile devices */
  
     /* Copy the text inside the text field */
    navigator.clipboard.writeText(copyText.value);
  
    /* Alert the copied text */
    alert("Copied the text: " + copyText.value);
