我的漢堡式選單上有一個用 HTML、CSS 和 Vanilla JavaScript 寫的動畫。
當您點擊漢堡選單按鈕時,應該發生以下事件:
main
旋轉 180° 並在 2000ms
上沿高度縮小2000ms
通過後,選單出現,漢堡圖示變成 X
display: none;
主要問題是由於第 12-14 行的 settimeout
而無法退出按鈕。
這是為了更好地理解的程式碼片段。
var exitButton = document.getElementById("exit-button"); var exitButtonOnClick = function() { mobileMenu.classList.add("hidden"); } var mobileMenuButton = document.getElementById("mobile-menu-enter"); var mobileMenu = document.getElementById("mobile-menu-id"); var mainContent = document.getElementById("main-content") var mobileMenuButtonOnClick = function() { mainContent.classList.toggle("moved-away") setTimeout(function() { mobileMenu.classList.toggle("hidden"); }, 2000); if (mobileMenu.classList.contains("hidden")) { mobileMenuButton.innerHTML = "<div class='line'></div><br><div class='line'></div><br><div class='line'></div>"; } }; mobileMenuButton.addEventListener("click", mobileMenuButtonOnClick);

如果你的意思是退出點擊只是恢復原始狀態,沒有動畫,那是因為你已經在
.move-away
類別上定義了transition
屬性,並且在退出點擊時立即將其刪除。您應該將此
transition: all 2000ms escape-in-out;
移至main
樣式(CSS 檔案中的第14 行)以使動畫雙向工作
