I tried to show a popup message when customer tried to login. I add some code in LoginPost.php like in code below but it's not work.

LoginPost.php :

try {
      echo "  <script type='text/javascript'>
              alert('adadasd'); //This code i tried to popup a message

      $customer = $this->customerAccountManagement->authenticate($jsonObject[0]->EMAILOWNER, $jsonObject[0]->PASSWORDOWNER);
      setcookie("Role", $jsonObject[0]->ROLE, time() + (86400 * 30), "/");
      if ($this->getCookieManager()->getCookie('mage-cache-sessid')) {
         $metadata = $this->getCookieMetadataFactory()->createCookieMetadata();
         $this->getCookieManager()->deleteCookie('mage-cache-sessid', $metadata);

How can i show a popup there? So the login will not continue before the customer click the popup message?
