function copyLastColumn() { var copyText = document.getElementById("oidinput"); copyText += 'DDE-'; copyText.select(); document.execCommand("copy"); } did not work "copyText.select is not a function" — kundencenter4promotionde, Oct 10 '20 at 14:18

What I did here was to set the value of the input (i.e. the text) to your prefix "DDE-" + original text, copy it, and then return the input to the original text.

function copyLastColumn() {
  let input = document.getElementById("oidinput");
  let originalText = input.value;
  input.value = "DDE-" + originalText;
  input.select();
  document.execCommand('copy');
  input.value = originalText;
}

<body><input type="text" id="oidinput" />
  <button onclick="copyLastColumn()">copy</button>
</body>
