javascript - 单击时功能不起作用，没有任何反应

Question

又一个问题对不起。我不明白为什么一旦我点击浏览我们的产品部分，它应该动画并显示一些图像，但目前，它没有做任何事情。但是，在网络风暴中并没有错。我真的很难确定问题发生在哪里。

var $menuWrap = $('#menu-wrap'),
    $body = $('body'),
    $menuTitle = $('#menu-title'),
    $close = $('#close'),
    $menuCards = $('.menu-card'),
    $menuInner = $('#menu-inner'),
    $menuLink = $('#menu-link');

setCardHeight();
$(window).resize(setCardHeight);

$menuLink.on('click', function(e) {
    e.preventDefault();
    showOverlay();
});

$close.on('click', function(e) {
    e.preventDefault();
    hideOverlay();
});

function showOverlay() {
    $body.addClass('menu-on');
    $menuWrap.addClass('display').addClass('visible');
    setTimeout(function() {
        $menuTitle.addClass('on');
        $close.addClass('on');
    }, 200);
    $menuCards.each(function(i) {
        var $card = $(this);
        setTimeout(function() {
            $card.addClass('on');
        }, 200 + 50 * i);
    });
}

function hideOverlay() {
    $body.removeClass('menu-on');
    $menuCards.removeClass('on');
    $menuTitle.removeClass('on');
    $close.removeClass('on');
    setTimeout(function() {
        $menuWrap.removeClass('display').removeClass('visible');
    }, 350);
}

function setCardHeight() {
    var windowWidth = $(window).width();
    var topVal;
    if (windowWidth >= 1300) {
        topVal = ($(window).height() - 700) / 2;
    } else {
        topVal = ($(window).height() - 200 - (windowWidth / 1300 * 513)) / 2;
    }
    if (topVal < 10) {
        topVal = 10;
    }
    $menuInner.css('top', topVal);
}
