单击时切换导航栏

Question

我有一个创建导航栏的脚本，它只能使下拉菜单在它悬停时才能打开，问题是当此通过移动浏览器访问时，下拉菜单无法打开，如何修改此脚本才能使下拉菜单在单击父菜单时打开

<div class="collapse navbar-collapse offset w-100" id="navbarSupportedContent">
            <div class="row w-100 mr-0">
              <div class="col-lg-7 pr-0">
                <ul class="nav navbar-nav center_nav pull-right">
                  <li class="nav-item ">
                    <a class="nav-link" href="index.html">Home</a>
                  </li>
                  <li class="nav-item submenu dropdown">
                    <a href="#" class="nav-link dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true"
                      aria-expanded="false">Paket</a>
                    <ul class="dropdown-menu">
                      <li class="nav-item">
                        <a class="nav-link" href="category.html">Pestgre</a>
                      </li>

                  </li>
                  <li class="nav-item submenu dropdown">

Answer 1

对于手机版本，我会使用汉堡包菜单(如果你不知道这三行)。您可以找到图标或将其设置为您自己的图标。在javascript或jquery中，比如

const getMenu = document.getElementById("menuButtonsId"); //be sure to call this code after after the document has loaded, or else javascript won't find the button or icon.
getMenu.onclick(function(){
  if (the menu is closed) {
    open the menu
  } else {
    close the menu
  }
})

我对jquery了解不多，但我认为您可以这样做

$("#menuButtonsId").click(function() {
  if (the menu is closed) {
    open the menu
  } else {
    close the menu
  }
})

只需填写我放入代码中的占位符文本即可。我希望这回答了你的问题！
