链接到锚点ID时删除移动菜单

Question

我不是最大的JS开发人员，所以它可能很简单。但是我在这里做了一个JSfiddle：https://jsfiddle.net/4xm3whzf/1/

我的问题是，由于我只是链接到同一页面上的标题，所以在选择菜单项后菜单不会关闭。如何确保它向下滚动并且菜单又消失了？

$(document).ready(function() {
    $(".mobile_menu").simpleMobileMenu({
      onMenuLoad: function(menu) {
        console.log(menu)
        console.log("menu loaded")
      },
      onMenuToggle: function(menu, opened) {
        console.log(opened)
      }
    });
  })

您可以添加简单的事件侦听器，单击链接即可触发该事件。您可以在下面查看代码示例。

Array.from(document.querySelectorAll('ul.mobile_menu > li > a'), b => b.addEventListener('click', () => {
  Array.from(
    document.querySelectorAll("body.mmactive, div#sm_menu_ham"),
    e => e.className = "")

  document.getElementsByClassName('sm_menu_outer')[0].classList.remove("active");
}, false));
