javascript - 如何通过单击外部来关闭汉堡菜单

Question

我试图通过在菜单外部单击来关闭我的汉堡包菜单。现在关闭汉堡菜单的唯一方法是单击 X 图标。我仍然希望菜单能够通过单击图标关闭，但也可以选择通过单击菜单外部来关闭它。有没有人有任何解决方案？

    jQuery(document).ready(function() {
  jQuery(".submenu").slideUp("fast");
  jQuery(".menutoggle").click(function() {
    var id = jQuery(this).attr("id").replace("toggle", "submenu");
    jQuery("#" + id).slideToggle("fast");
  });

  jQuery("#hamburger-nav-icon").click(function() {
    jQuery(this).toggleClass("open");
    jQuery("body").css("overflow", "hidden");
    if (jQuery("#hamburger-menu-cover").css("opacity") == "0") {
      jQuery("#hamburger-menu-cover").css("opacity", "1");
      jQuery("#hamburger-menu-cover").fadeIn(300).css("display", "table");
      jQuery("body").css("overflow", "hidden");
    } else {
      jQuery("#hamburger-menu-cover").css("opacity", "0");
      jQuery("#hamburger-menu-cover").fadeOut(300).css("display", "none");
      jQuery("body").css("overflow", "visible");
    }
  });
});

Answer 1

基本上，在 body 本身上添加一个点击事件，并确保您不想使用 e.stopPropagation() 触发关闭 block 点击事件.

jQuery('body').on('click', function() {
  // code to close hamburger
});

jQuery('.hamburger-menu').on('click', function (e) {
  e.stopPropagation();
  // other code
});

打开时应用这些，关闭时删除它们。

你可以这样添加:

jQuery(document).ready(function() {
    jQuery(".submenu").slideUp("fast");
  jQuery(".menutoggle").click(function(){
    var id = jQuery(this).attr("id").replace("toggle","submenu");
    jQuery("#" + id).slideToggle("fast");    
  })


 const bodyClick = function () { jQuery('#hamburger-nav-icon').click() };

 jQuery('#hamburger-nav-icon').click(function() {
    jQuery(this).toggleClass('open');
      jQuery('body').css('overflow','hidden');  
    jQuery('.#hamburger-menu').click(function (e) { e.stopPropagation(); });
    if (jQuery('#hamburger-menu-cover').css('opacity') == '0') {
      jQuery('#hamburger-menu-cover').css('opacity', '1');
      jQuery('#hamburger-menu-cover').fadeIn(300).css('display', 'table'); 
        jQuery('body').css('overflow','hidden').on('click', bodyClick);
    } else {
      jQuery('#hamburger-menu-cover').css('opacity', '0');
      jQuery('#hamburger-menu-cover').fadeOut(300).css('display', 'none');
        jQuery('body').css('overflow','visible').off('click', bodyClick);
    }
  });
});

可能不完美，但应该让您知道该怎么做。
