javascript - Bootstrap 侧面切换菜单，单击时关闭

Question

我想使用https://startbootstrap.com/template-overviews/simple-sidebar/向我的网站添加侧边菜单，但我想添加功能，以便单击时菜单将关闭。这是我的代码

<script>
   jQuery(document).ready(function($) {
    $("#menu-toggle").click(function(e) {
        e.preventDefault();
        $("#wrapper").toggleClass("toggled");

     $("#page-content-wrapper").click(function(ev){
         ev.preventDefault();
        $("#menu-toggle").click();
        $(this).off(ev);
        });

    });


           });
    </script>

并尝试这样做

 <script>
   jQuery(document).ready(function($) {
    $("#menu-toggle").click(function(e) {
        e.preventDefault();
        $("#wrapper").toggleClass("toggled");

     $("#page-content-wrapper").click(function(ev){
         ev.preventDefault();
         $(this).off(ev);
         console.log($("#wrapper"));
         if( $( "#wrapper" ).hasClass('.toggled') ) {
           $("#menu-toggle").click();
        }

        });

    });


           });
    </script>

但这两种方法都没有显示出我想要的结果

您可以使用下面的代码块来实现确保您的 Body 或 Wrapper 的高度为 100% 使其工作，否则它将不会触发任何点击事件。

您只需在 Body 或父 Div 上绑定(bind)一个点击事件，并在其中检查单击的元素不是菜单 sidebar-wrapper 的 ID，并且Toogle 按钮菜单切换。

$('#wrapper').click(function(evt){
       if(evt.target.id == "sidebar-wrapper" || evt.target.id == "menu-toggle" )
          return false;
         $("#menu-toggle").click();     


});
