這是我第一次把CSS代碼，如果你想要更多的代碼，請問我。 如何將滑下操作更改爲上移操作？我想把菜單放在頁面的底部。 我搜索了很多文檔，但沒有找到一個好的解決方案。如何使滑動下拉菜單向上滑動？
感謝。
$(document).ready(function() { \t
\t $('#nav li').hover(function() {
\t \t $('ul', this).slideDown(200);
\t \t $(this).children('a:first').addClass("hov");
\t }, function() {
\t \t $('ul', this).slideUp(100);
\t \t $(this).children('a:first').removeClass("hov"); \t \t
\t });
});.wrap {
