javascript - 单击按钮切换 Accordion 选项卡的脚本

转载作者：太空宇宙更新时间：2023-11-04 11:30:11

我重用了网站中的一些代码并制作了一个购物车 Accordion 模块。我将整个代码作为 codepen 上的笔。这是笔的链接:http://codepen.io/applecool/pen/YXaJLa

<div class="summary">
 <button class="expand btn btn-lg">Collapse All for Summary</button>
</div>

上面按钮的 HTML:我在底部添加了一个名为“为摘要折叠所有”的按钮。此按钮的用途:当用户单击该按钮时，它应该打开所有 Accordion 选项卡，再次单击它时，应该关闭 Accordion 选项卡。 [即典型的切换功能]。

我写了一个小的 javascript 函数来切换 Accordion 选项卡，但它有很多错误。它完美地完成了工作，但问题是，一旦我点击按钮，一般点击选项卡就不起作用了。即，当您打开代码笔并单击 Accordion 选项卡时，它会顺利打开和关闭。但是在添加切换按钮功能后，您启动页面，单击“为摘要折叠所有”按钮， Accordion 选项卡工作正常。现在，当您尝试单击任何关闭或打开的 Accordion 选项卡时，该选项卡既不会打开也不会关闭。我认为问题肯定出在我正在使用 CSS 在 javascript 中所做的类更改。

脚本:

$('.expand').click(function(){

   if($('.accordionItem.is-collapsed').css('max-height')== '0px'){
    $('.accordionItem.is-collapsed').css({
      'max-height': '900px'
     });

   }else if($('.accordionItem.is-collapsed').css('max-height')== '900px'){
    $('.accordionItem.is-collapsed').css({
      'max-height': '0px'
     });

    }

});

特定于上述脚本和按钮 div 的 CSS:

 .accordionItem.is-collapsed{
   max-height: 0px;
  }

如有任何帮助，我们将不胜感激。如果有任何解决方法，我也很乐意遵循。请让我知道我在这里犯了什么愚蠢的错误。 :)

谢谢。

干杯，.SH

最佳答案

我稍微编辑了您的代码以包含展开/折叠所有功能。我认为它很草率，你应该在实现之前清理它，但它完成了工作。

根据您是单击单个元素还是展开/折叠全部按钮，添加项利用数组循环遍历一个元素或所有元素。这样做的好处是它与原始代码相同，但可以处理切换多个元素的类。

我在解释更多的 JavaScript 中添加了一些注释。

//uses classList, setAttribute, and querySelectorAll
//if you want this to work in IE8/9 youll need to polyfill these
