JavaScript

该特效中使用jQuery代码来处理汉堡包按钮的点击事件和堆叠卡片菜单的切换事件。

$(document).ready(function () {    var $demo = $('.demo');    var numOfSections = $('.demo__section').length;    $(document).on('click', '.demo__menu-btn', function () {        $demo.addClass('menu-active');    });    $(document).on('click', '.demo__close-menu', function () {        $demo.removeClass('menu-active');    });    $(document).on('click', '.demo.menu-active .demo__section', function () {        var $section = $(this);        var index = +$section.data('section');        $('.demo__section.active').removeClass('active');        $('.demo__section.inactive').removeClass('inactive');        $section.addClass('active');        $demo.removeClass('menu-active');        for (var i = index + 1; i <= numOfSections; i++) {            if (window.CP.shouldStopExecution(1)) {                break;            }            $('.demo__section[data-section=' + i + ']').addClass('inactive');        }        window.CP.exitedLoop(1);    });});
