Question

我有以下内容

function subNavToggle() {
    var subNav = document.getElementById("subnav-section");
    if (subNav.className === "navigation-subnav") {
        subNav.className += " responsive";
    } else {
        subNav.className = "navigation-subnav";
    }
 }

我试图在菜单外单击时关闭展开的菜单。

我有这个，它会关闭菜单，但它也会关闭汉堡菜单 - 防止用户再次打开。

 $(document).click(function(event) { 
     var $target = $(event.target);
     if(!$target.closest('.sub_nav_links').length && 
     $('.sub_nav_links').is(":visible")) {
       $('.sub_nav_links').hide();
     }        
   });

还认为我可以通过以下方式逃脱，但实际上恰恰相反。在菜单项外打开。

window.onclick = subNav;

Answer 1

  $('html').on('click, touchend', function (e) {
    // Close hamburger menu when tapping outside
    if ($(e.target).closest('#subnav-section').length == 0) {
        var opened = $('.navigation-subnav').hasClass('responsive');
        if (opened === true) {
            $('.navigation-subnav').collapse('hide');
        }
    }
});

Answer 2

// to hide
$(document).click(function(){
 $("#submenu").hide();
});

// you could possibly prevent to hide menu while using navigation
$("#menu").click(function(e){
 e.stopPropagation();
});
