JS code inside Pagebuilder strips

Hello, dear users! Can you help me to sort out with the js code I wrote inside PB. On clicking button there will be apperance of a modal window. Does this js code “onclick” work if you add it inside pagebuilder code strips at the php file?

$output  .= '<a href="#" onclick="document.getElementById("btn-1508746468").style.display="block"" id="btn-1508746468" class="sppb-btn sppb-btn-primary sppb-btn-rounded sp-tooltip" data-toggle="tooltip" data-placement="top" data-original-title="Кнопка временно не работает, приносим свои извенения. Для заказа, звоните: +7 (926) 962-42-21 | +7 (926) 493-51-99"><i class="fa fa-shopping-cart"></i>ОФОРМИТЬ ДОСТАВКУ</a>';

$output  .= '<div id="btn-1508746468" class="w3-modal">
    <div class="w3-modal-content w3-card-4">
      <header class="w3-container w3-teal"> 
        <span onclick="document.getElementById("btn-1508746468").style.display="none"" 
        class="w3-button w3-display-topright">×</span>
        <h2>Modal Header</h2>
      </header>
      <div class="w3-container">
        You have two options to close this modal:


        Click on the "x" or click anywhere outside of the modal!


      </div>
      <footer class="w3-container w3-teal">
        Modal Footer


      </footer>
    </div>
  </div>';
