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，侧边栏被打开，鼠标离开时，侧边栏被关闭。

我检查了其他解决方案，并试图在我的代码中实现它，但它不工作。

这里是我的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> 

感谢

为了结束对鼠标离开你可以写菜单：

$('.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'); 
 
    }); 
 
});
