点击链接和外面时关闭菜单汉堡包

Question

我为我的网站创建了一个简单的汉堡包菜单，我点击一个链接并转到我放入的锚点后无法关闭它，当我点击菜单时它也会关闭。

我的HTML是：

  $(document).ready(function() {
    $('.navbar-fostrap').click(function() {
      $('.nav-fostrap').toggleClass('visible');
      $('body').toggleClass('cover-bg');
    });
  });

nav {
  height: 60px;
  text-align: center;
  position: relative;
  width: width:100%;
  margin: auto;
  z-index: 100000;
}

.navbar-default {
  transition: 500ms ease;
  background: transparent;
}

.navbar-default.scrolled {
  background: rgba(28, 28, 28, 0.8);
}

a.title {
  float: left;

我正在为我的课程的专业能力项目开发这个网站，所以欢迎任何帮助。如果有人能帮助我，我非常感激，谢谢。

您可以使用这部分代码并添加您想要的任何其他逻辑。

$(document).click(function(e) {
    var target = e.target;
    if (
      !$(target).is(".navbar-fostrap") &&
      !$(target).parents(".navbar-fostrap").length &&
      !$(target).parents(".nav-fostrap").length
    ) {
      $(".nav-fostrap").removeClass("visible");
      $("body").removeClass("cover-bg");
    }
});

这里的完整代码

$(document).ready(function() {
  $(".navbar-fostrap").click(function() {
    $(".nav-fostrap").toggleClass("visible");
    $("body").toggleClass("cover-bg");
  });
  $(document).click(function(e) {
    var target = e.target;
    if (!$(target).is(".navbar-fostrap") &&
      !$(target).parents(".navbar-fostrap").length &&
      !$(target).parents(".nav-fostrap").length
    ) {
      $(".nav-fostrap").removeClass("visible");
      $("body").removeClass("cover-bg");
    }
  });
});
