I try corny like this - the error "yaCounter99999 is not defined"

<script type="text/javascript">
  var clientid = yaCounter99999.getClientID();
  console.log(clientid);
</script>

PS: The meter number is correct, not the one in the example.

Answer 1

Try like this

<script type="text/javascript">
window.onload = function(){
  var clientid = yaCounter99999.getClientID();
  console.log(clientid);
}
</script>

The counter does not have time to initialize, I think so

Answer 2

alternatively you can use:

function GetYMCID() {    
    var match = document.cookie.match('(?:^|;)\\s*_ym_uid=([^;]*)');
    return (match) ? decodeURIComponent(match[1]) : false;
}
