javascript - 单页响应式下拉菜单 - 在 "a"单击时隐藏下拉菜单

Question

使用响应式下拉菜单构建单个页面布局。我遇到的问题是，我是否可以在 .js 文件中添加一个调用，以便在用户单击“a”跳转链接后折叠打开的菜单。

(function($) {
  $.fn.menumaker = function(options) {
    var cssmenu = $(this),
      settings = $.extend({
        format: "dropdown",
        sticky: false
      }, options);
    return this.each(function() {
      $(this).find(".button-mobile").on('click', function() {
        $(this).toggleClass('menu-opened');
        var mainmenu = $(this).next('ul');
        if (mainmenu.hasClass('open')) {
          mainmenu.slideToggle().removeClass('open');
        } else {
          mainmenu.slideToggle().addClass('open');
          if (settings.format === "dropdown") {
            mainmenu.find('ul').show();
          }
        }
      });
      cssmenu.find('li ul').parent().addClass('has-sub');
      multiTg = function() {
        cssmenu.find(".has-sub").prepend('<span class="submenu-button"></span>');
        cssmenu.find('.submenu-button').on('click', function() {
          $(this).toggleClass('submenu-opened');
          if ($(this).siblings('ul').hasClass('open')) {
            $(this).siblings('ul').removeClass('open').slideToggle();
          } else {
            $(this).siblings('ul').addClass('open').slideToggle();
          }
        });
      };
      if (settings.format === 'multitoggle') multiTg();
      else cssmenu.addClass('dropdown');
      if (settings.sticky === true) cssmenu.css('position', 'fixed');
      resizeFix = function() {
        var mediasize = 960;
        if ($(window).width() > mediasize) {
          cssmenu.find('ul').show();
        }
        if ($(window).width() <= mediasize) {
          cssmenu.find('ul').hide().removeClass('open');
        }
      };
      resizeFix();
      return $(window).on('resize', resizeFix);
    });
  };
})(jQuery);

Answer 1

在调用 .menumaker() 之后，在“a”标签上添加一个监听器并触发一个函数以关闭所有菜单。

$("#cssmenu ul li a").click(function(){
    //fire another click to the menu button to toggle it closed.
});
