jQuery复杂的手风琴

标签： javascript jquery css accordion

我90％在那里。我有一个手风琴模块，我正在努力完成，但有一件作品让我望而却步。

功能（工作）

  • 手风琴已关闭（默认）
  • 用户点击底栏（“+”符号）
  • 模块打开
  • 模块打开
    • 顶部区域更改为蓝色背景
    • 顶部区域中的图标变为黄色
    • “+”更改为“ - ”
  • 用户点击另一个手风琴模块
  • 关闭以前打开的模块

功能（缺失/未按预期工作）。当用户单击下一个模块将其打开时，先前打开的模块将关闭（正常工作），但是不会删除这些类以使其恢复到默认状态。

我意识到我的jQ可能不是最优化的;所以我也很欣赏这方面的任何建议。

// jQuery Plugins
$(function(){
  "use strict";

  $('.mod-accordion-bottom').click(function(){
    $(this).removeClass('active');
    $(this).parent().find('.mod-accordion-top').removeClass('open');
    $(this).parent().find('i.fa').removeClass('active');
    $(this).find('i').addClass('fa-plus').removeClass('fa-minus');
    $('.mod-accordion-content').slideUp();


    if( $(this).prev().is(':hidden') === true ) {
      $(this).prev().slideDown('normal');
      $(this).parent().find('.mod-accordion-top').addClass('open');
      $(this).addClass('active');
      $(this).parent().find('i.fa').addClass('active');
      $(this).find('i').removeClass('fa-plus').addClass('fa-minus');
    }
  });

您可以通过将活动类添加到wrap元素而不是将其添加到每个元素来简化此操作。这将有助于我们简化脚本

// jQuery Plugins
$(function() {
  "use strict";
  // Accordion Section
  $('.mod-accordion-bottom').click(function() {
    var $wrap = $(this).closest('.mod-accordion-wrap').toggleClass('active'),
      active = $wrap.hasClass('active');
    $wrap.find('.mod-accordion-bottom i').toggleClass('fa-minus', active).toggleClass('fa-plus', !active);
    $wrap.find('.mod-accordion-content')[active ? 'slideDown' : 'slideUp']('normal');

    if (active) {
      var $other = $('.mod-accordion-wrap.active').not($wrap).removeClass('active');
      $other.find('.mod-accordion-content').slideUp();
      $other.find('.mod-accordion-bottom i').removeClass('fa-minus').addClass('fa-plus');
    }
  });
