我的問題是我無法自動顯示我的模態。在最好的情況下，我需要一個打開模式的計時器（例如，頁面加載后 10 秒）。https://codepen.io/martin-len/pen/ExjJayx<script>// Working metods to open modal with button.var modal = document.getElementById("myModal");var btn = document.getElementById("myBtn");btn.onclick = function() {  modal.style.display = "block";}// And here im trying open modal automaticaly. All methods dont work.// method 1$(document).ready(function(){modal.style.display = "block";});// method 2window.onload = function(){     modal.style.display = "block";}$(document).ready(function(){$("#myModal").modal('show');});</script>
