jQuery汉堡菜单问题

Question

我使用jQuery创建了一个汉堡菜单，但需要你的帮助来找出最后几位。首先，我向导航内部的打开菜单链接添加了一个过渡效果，该链接无法正常工作。其次，我需要在汉堡关闭时关闭#menu_list。目前它仍然开放。

<div id="mobile_navBar">

  <div id="burger_icon">
    <span></span>
    <span></span>
    <span></span>
    <span></span>
  </div>
</div>

<nav>

  <ul>
    <img class="nav_decoration" src="images/top%20frame.png" alt="">
    <li id="open_menu"><a href="#">open menu</a></li>
    <ul id="menu_list">
      <li class="auto_close"><a href="#welcomeAnchor">Welcome</a></li>
      <li class="auto_close"><a href="#menuAnchor">Menu</a></li>
      <li class="auto_close"><a href="#timesAnchor">Opening Times</a></li>
    </ul>
    <img class="nav_decoration" src="images/Base%20Frame.png" alt="">
  </ul>
</nav>

#contact_title span{

    padding: 0.25em 0;
    display: block;
}

#mob_num{
    font-size: 2.5em;
}

#mob_icons{
    display: block;
    font-size: 1em;
    padding: 0 !important;
}

jQuery的：

$(document).ready(function() {
  $("#burger_icon, .auto_close").click(function() {

    $("body").toggleClass("no_scroll");
    $("nav").toggleClass("show");
    $("#burger_icon").toggleClass("open");

    $("#open_menu").click(function() {
      $("#menu_list").toggleClass("show");
      $("#open_menu").toggleClass("hide");
    });
  });
});

Answer 1

在$("#burger_icon, .auto_close")的点击事件中添加以下代码。

$("#menu_list").removeClass("show");

$("#open_menu").removeClass("hide");

这将重置内部菜单。你的小提琴过渡效果很好。

Answer 2

Here is the updated demo with your desired functionality with your updated code    

$(document).ready(function() {
  $("#burger_icon, .auto_close").click(function() {

    $("body").toggleClass("no_scroll");
    $("nav").toggleClass("show");
    $("#burger_icon").toggleClass("open");

    $("#open_menu").click(function() {
      $("#menu_list").toggleClass("show");
      $("#open_menu").toggleClass("hide");
    });
    
      if($('#menu_list').hasClass('show')) {
        $('#menu_list').removeClass('show');
        $("#open_menu").removeClass("hide");
      }
  });
});
