问题描述

我刚刚开始建立网站。 我仍然对 JavaScript 知之甚少，所以我正在寻找现成的代码片段并为我的网站定制它们（当然还要继续学习 JavaScript）。 一般来说，我制作了一个窗口宽度为 768 的菜单，它变成了一个汉堡菜单。 通过按钮和它的点实现了它的打开和关闭。 只有在我看来，结果是歪的。 请帮我解决。

$(function () {


    /* Fixed Header */
    let header = $("#header");
    let intro = $("#intro");
    let introH = intro.innerHeight();
    let scrollPos = $(window).scrollTop();
    let nav = $("#menu");
    let navToggle = $("#navToggle");

    //Header fixed

    checkScroll(scrollPos, introH);

    $(window).on("scroll resize", function () {
        introH = intro.innerHeight();
        scrollPos = $(this).scrollTop();

        checkScroll(scrollPos, introH);
    });

    function checkScroll(scrollPos, introH) {
        if (scrollPos > introH) {
            header.addClass("header__fixed");
        } else {
            header.removeClass("header__fixed");
        }
    }
    
    //Active

    var sections = $('section')
        
        , nav_height = nav.outerHeight();

    $(window).on('scroll', function () {
        var cur_pos = $(this).scrollTop();

        sections.each(function () {
            var top = $(this).offset().top - nav_height,
                bottom = top + $(this).outerHeight();

            if (cur_pos >= top && cur_pos <= bottom) {
                nav.find('a').removeClass('active');
                sections.removeClass('active');

                $(this).addClass('active');
                nav.find('a[href="#' + $(this).attr('id') + '"]').addClass('active');
            }
        });
    });

    //Smooth scroll

    nav.find('a').on('click', function () {
        var $el = $(this)
            , id = $el.attr('href');

        $('html, body').animate({
            scrollTop: $(id).offset().top - 70
        }, 500);

        return false;
    });

    //Toggle menu

    navToggle.on('click', function () {
        if ($(this).hasClass('menu__show')) {
            $(this).removeClass('menu__show');
            nav.slideUp();
        } else {
            $(this).addClass('menu__show');
            nav.slideDown();
        }
    });

    $(window).resize(function() {
        if ($(window).width() <= 768) {
            $(".menu__item a").click(function () {
                nav.slideToggle(500, function () {
                    $(this).hide();
                    navToggle.removeClass('menu__show');
                });
            });
        } else {
            nav.show();
            $(".menu__item a").click(function () {
                nav.slideToggle(500, function () {
                    navToggle.removeClass('menu__show');
                });
            });
        }
    });

    
        


    //Filter

    let filter = $("[data-filter]");

    filter.on("click", function (event) {
        event.preventDefault();

        let cat = $(this).data('filter');

        if (cat == 'all') {
            $("[data-cat]").removeClass("hide");
        } else {
            $("[data-cat]").each(function () {
                let workCat = $(this).data('cat');

                if (workCat != cat) {
