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); });});
