This is my js-code, I thing I have a loop in the xhr request as it keeps loading even without the cookies function; I am trying to show the "TnC" if no cookie is there. However it keeps on replading the request if it is a no.

Also when I click on agree on the submit form it reloads.

Thank you a lot for the help

//cookies function:

   function setCookie(cname, cvalue, exdays) {
   if(document.getElementById('agree').checked){
    const d = new Date();
   d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
   let expires = "expires="+d.toUTCString();
   document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
   }   
   }

   function getCookie(cname) {
  var name = cname + "=";
  var ca = document.cookie.split(';');
  for(var i=0; i<ca.length; i++) {
    var c = ca[i];
    while (c.charAt(0)==' ') c = c.substring(1);
    if (c.indexOf(name) == 0) return c.substring(name.length,c.length);
   }
    return "";
 }

//cokkie on load + XHR

  function checkCookieOnLoad() {
  if(getCookie("clicklink") === "yes") {

                            if(this.currentTime >= 4.8) {
                                // pause the playback
                                this.pause();
                                this.remove();
