Click on the button to copy the text from the text field. Try to paste the text (e.g. ctrl+v) afterwards in a different window, to see the effect.
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("Kopierat text: " + copyText.value); }
