标签: javascript jquery html css hamburger-menu

我一直试图让这个汉堡包菜单工作时间最长,而且我已经尝试了很多,但我只是因为某种原因而继续在圈子里打开(菜单不会打开)菜单未打开是问题:(),

我从学习如何从本教程创建菜单中获得了菜单 - > Youtube Link

请告诉我如何解决这个问题或者转介给我类似的帖子,谢谢!



$(document).ready(function() {
  $(".burger-nav").on("click", function() {
    $("header nav ul").toggleClass("open");
  });

});

header nav ul {
  height: 0;
  overflow: hidden;
  background: #6134A3;
}

header nav ul.open {
  height: auto;
}

.burger-nav {
  padding: 0px;
  margin: 0px;
  display: block;
  height: 40px;
  width: 100%;
  cursor: pointer;
  background-image: url(images/nav.png);
  background-repeat: no-repeat;
  background-size: 10%;
  background-position: 97%;
  background-color: #502196;
}

因为身高:自动财产。你应该设定一定的价值。像400px,或100vh。或者您可以尝试这样的事情:

$(document).ready(function() {
    $(".burger-nav").on("click", function() {
          $("header nav ul").slideToggle(400);
    });
});

header nav ul {
  height: auto;
  overflow: hidden;
  display: none;
  background: #6134A3;
}

使用最新版本的jquery ....

<head>
  <title>MENU</title>
  <link rel="stylesheet" href="slicknav.css" />
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
