javascript - 需要禁用下拉菜单的淡出功能(仅)

Question

我的移动模式菜单有问题。 onClick 它淡出。我想保留此设置，但我不希望它在单击下拉部分时淡出。这是链接:http://jsfiddle.net/zLLzrs6b/3/感谢您的帮助!

html:

<nav id="nav-wrap"> <a class="mobile-btn" href="#nav-wrap" title="Show navigation">Show Menu</a>
 <a class="mobile-btn" href="#" title="Hide navigation">Hide Menu</a> 
    <ul id="nav" class="nav">
        <li><a class="smoothscroll mobile" href="#about">about</a>
        </li>
        <li><a class="smoothscroll mobile" href="#documents">blog</a>
        </li>
        <li class="nav-item"><a href="#">dropdown</a> 
            <ul class="langop">
                <li><a href="#">otion 1</a>
                </li>
                <li><a href="#">otion 2</a>
                </li>
            </ul>
        </li>
    </ul>
</nav>

CSS:

.langop {
    display:none;
    position: relative;
    width:auto;
}
.nav-item:hover .langop {
    display: block;
}

java:

var toggle_button = $("<a>", {
    id: "toggle-btn",
    html: "Menu",
    title: "Menu",
    href: "#"
});
var nav_wrap = $('nav#nav-wrap')
var nav = $("ul#nav");


nav_wrap.find('a.mobile-btn').remove();
nav_wrap.prepend(toggle_button);

toggle_button.on("click", function (e) {
    e.preventDefault();
    nav.slideToggle("fast");
});

if (toggle_button.is(':visible')) nav.addClass('mobile');
$(window).resize(function () {
    if (toggle_button.is(':visible')) nav.addClass('mobile');
    else nav.removeClass('mobile');
});

$('ul#nav li a').on("click", function () {
    if (nav.hasClass('mobile')) nav.fadeOut('fast');
});
