javascript - 即使表被切换为不可见，粘性标题也会出现在滚动条上

我是一个菜鸟程序员，对于表格有一些问题，表格最终将成为网站的一部分，该网站将在表格中包含其他图形。为了避免潜在的视觉混乱，我希望用户能够打开或关闭表格（此处显示来自名为“ testdatastickyheadersissue.csv”的外部CSV文件的数据）。打开表格后，用户应该能够对表格进行排序，并在向下滚动页面时看到粘性标头。下面的代码使用tablesorter插件及其一些小部件，这些功能对于所有这些功能都非常有效，除了关闭表时不会在表的其余部分禁用粘性标题之外，因此粘性标题仍会显示向下滚动页面时，即使表格的其余部分不可见。关闭表格后，如何隐藏粘性标题？我确定可能有一个简单的解决方法，但是我很沮丧，不胜感激。谢谢！

最佳答案

我似乎无法复制您正在描述的问题... demo）

实际上，使用visiblilty: hidden隐藏表会导致这种情况，但是看起来该表已被display: none和visibility: hidden隐藏。

由于您使用的是jQuery插件tablesorter，因此我将修改用于隐藏表格的代码以使用jQuery：

的HTML

<a href="#" class="toggle">Click here to display/hide data table for counties.</a>


脚本

jQuery(function($){
  $('.toggle').click(function(){
    var isHidden = $('#CSVTable').toggle().is(':hidden');
    $('#displayText').html( (isHidden ? 'Show' : 'Hide') + ' data table for counties');
    return false;
  });
});
