Javascript onclick菜单按钮显示侧边栏，onmouseleave隐藏侧边栏

Question

我有一个默认隐藏的侧边栏和一个触发侧边栏的菜单按钮。到目前为止，一切正常，但我想要的是，当我点击菜单时，侧边栏会打开，鼠标离开时，侧边栏会关闭。

我已经检查了其他解决方案，并尝试在我的代码中实现它，但它不起作用。

这是我的html和js

//html
<div id="wrapper">

<!-- sidebar content -->

    <!-- Menu button -->
    <div id="page-content-wrapper">
        <button type="button" class="hamburger is-closed" data-toggle="offcanvas">
            <span class="hamb-top"></span>
            <span class="hamb-middle"></span>
            <span class="hamb-bottom"></span>
        </button>
    </div>
</div>


//js
<script type="text/javascript">
    $(document).ready(function () {
      var trigger = $('.hamburger'),
          overlay = $('.overlay'),
         isClosed = false;

        trigger.click(function () {
          hamburger_cross();  
        });

        function hamburger_cross() {

          if (isClosed == true) {          
            overlay.hide();
            trigger.removeClass('is-open');
            trigger.addClass('is-closed');
            isClosed = false;
          } else {   
            overlay.show();
            trigger.removeClass('is-closed');
            trigger.addClass('is-open');
            isClosed = true;
          }
      }

      $('[data-toggle="offcanvas"]').click(function () {
            $('#wrapper').toggleClass('toggled');
      });  
    });
</script>

要关闭mouseleave上的菜单，您可以写：

$('.navbar').on('mouseleave', function (e) {
   trigger.click(); // simulate the action you now do to close the menu
})

$(document).ready(function () {
  var trigger = $('.hamburger'),
      overlay = $('.overlay'),
      isClosed = false;

  trigger.click(function () {
    hamburger_cross();
  });
  $('.navbar').on('mouseleave', function (e) {
    trigger.click();
  })

  function hamburger_cross() {

    if (isClosed == true) {
      overlay.hide();
      trigger.removeClass('is-open');
      trigger.addClass('is-closed');
      isClosed = false;
    } else {
      overlay.show();
      trigger.removeClass('is-closed');
      trigger.addClass('is-open');
      isClosed = true;
    }
  }

  $('[data-toggle="offcanvas"]').click(function () {
    $('#wrapper').toggleClass('toggled');
  });
});
