我有一個菜單，當你點擊漢堡圖標時，我想下拉菜單。點擊按鈕後顯示列表項，但當按鈕未被點擊時仍然可以看到列表項。我無法弄清楚如何隱藏菜單。切換菜單列表項目顯示
我這裏的代碼：Codepen
function myFunction() {
\t var x = document.getElementById("myTopnav");
\t if (x.className === "topnav") {
\t x.className += " responsive";
\t } else {
\t x.className = "topnav";
\t }
\t }
$(document).ready(function() {
$('#nav-icon3').on('click', function() {
$(this).toggleClass('open');
});
