Javascript

Question

所以我有这个边栏，我想切换它的行为。而不是像这样关闭它：

我想在网站启动时保持打开状态：

这是javascript

<script type="text/javascript">   
  $(function() {
    $('.navbar-toggler').on('click', function(event) {
      event.preventDefault();
      $(this).closest('.navbar-minimal').toggleClass('open');
    })
  });     
</script>

和Html

<nav class="navbar navbar-fixed-left navbar-minimal animate" role="navigation" id="sidebar-1">
  <div class="navbar-toggler animate">
    <span class="menu-icon"></span>
    <p id="menutab">Menu</p>
  </div>
  <ul class="navbar-menu animate">
    <li class="dropdown" id="dropdown-nav">
      <a href="#" class="animate dropdown-toggle" data-toggle="dropdown">
        <span class="desc animate" style="font-family: 'Roboto Condensed', sans-serif;">Top 5 Events</span>
        <span class="mini-icon"><img src="Images/ps/Events.png" id="mini-icon"></span>
      </a>
      <ul class="dropdown-menu" id="events">
        <iframe src="Php/events.php" id="iframe" frameborder="0" marginheight="0" marginwidth="0" width="100%" height="100%" scrolling="auto">
          <p>Your browser does not support iframes.</p>
        </iframe>
      </ul>
    </li>

Answer 1

<script type="text/javascript">   
    $(function () {
        $(this).closest('.navbar-minimal').toggleClass('open');
    });
    </script>

Answer 2

添加 class open to navbar-menu 它显示打开，当你点击关闭菜单时它会切换元素 ul.navbar-menu

 $(".navbar-toggler").click(function () {
    $(".navbar-menu").slideToggle();
   });

Answer 3

<nav class="navbar navbar-fixed-left navbar-minimal animate"

转到 html 标记中的上面一行并添加 class “open” 像这样

<nav class="navbar navbar-fixed-left navbar-minimal animate open"

所以会默认打开

Javascript - 侧边栏开关始终打开

Javascript - Sidebar toggle always open

html

toggle

twitter-bootstrap
