js代码:

(function ($) {      var cards = $('.card-drop'), toggler = cards.find('.toggle'), links = cards.find('ul>li>a'), li = links.parent('li'), count = links.length, width = 100;      li.each(function (i) {        $(this).css('z-index', count - i);      });      function setClosed() {        li.each(function (index) {          $(this).css('top', index * 4).css('width', width - index * 0.5 + '%').css('margin-left', index * 0.25 + '%');        });        li.addClass('closed');        toggler.removeClass('active');      }      setClosed();      toggler.on('mousedown', function () {        var $this = $(this);        if ($this.is('.active')) {          setClosed();        } else {          $this.addClass('active');          li.removeClass('closed');          li.each(function (index) {            $(this).css('top', 60 * (index + 1)).css('width', '100%').css('margin-left', '0px');          });        }      });      links.on('click', function (e) {        var $this = $(this), label = $this.data('label');        icon = $this.children('i').attr('class');        li.removeClass('active');        if ($this.parent('li').is('active')) {          $this.parent('li').removeClass('active');        } else {          $this.parent('li').addClass('active');        }        toggler.children('span').text(label);        toggler.children('i').removeClass().addClass(icon);        setClosed();        e.preventDefault;      });    }(jQuery));
