copy button for input field and add URL automatic when its coped-CodePudding

i have input field and copy button, visitors can write their phone number inside the input (ex: 123456789) and then click copy button to copy the numbers.

i want the visitor when click copy and past it anywhere it should be with URL example.com/123456789 so the URL add automatically and without ( ) mark.

i have this code but it does not work as i expect and i tried to modified still not work.

<input type="text" id="phonenumber">

<div >
<button type="button" onclick="myFunction()" onm ouseout="outFunc()">
  <span  id="myTooltip">Copy to clipboard</span>
  Copy text
  </button>
</div>

<script>
function myFunction() {
  var copyText = document.getElementById("phonenumber");
  copyText.select();
  copyText.setSelectionRange(0, 99999);
  navigator.clipboard.writeText(copyText.value);
  
  var tooltip = document.getElementById("myTooltip");
  tooltip.innerHTML = "Copied";
}

function outFunc() {
  var tooltip = document.getElementById("myTooltip");
  tooltip.innerHTML = "Copy to clipboard";
}
</script>

i've tried to do it like this var copyText = document.getElementById("example.com/","phonenumber"); But its not working, i add extra var but still not working

Here's the working example of the code:

Used string.substring(1) to remove the first character from the input text. Then simply added it to clipboard by appending example.com to it while writing it to clipboard
