[Vuejs]-Vuejs ajax call not working

✅

this.userName doesn’t exist.

You can also directly do this instead of passing by a variable :

 window.location.href="successfullycreated.php?userName="+ <?php echo "'{$_GET['userName']}'";?>;

As long as the new page has the param present you can just get it from the URL in JavaScript.

var userName = new URL(window.location.href).searchParams.get("userName");
