HTML 折叠表行与 jquery

Question

单击按钮"折叠"后尝试折叠行。但什么也没发生。

我做错了什么？

$(document).ready(function() {
  $('.clickme').click(function() {
    $(this).nextUntil('tr#test').slideToggle('slow');
  });
});

Answer 1

next直到元素的所有后续同级，直到(不包括(指定的元素。

按钮和tr#test不是同级。BUtton 没有任何兄弟姐妹，所以没有什么可显示的。

因此，您需要首先选择按钮的父级 (tr( 并在该 tr 上使用 nextAll，该 tr 是与tr#test的兄弟姐妹。此外，正如在另一个答案中指出的那样，不要使用重复的id，而是使用类代替class='test'

我想在"真实"应用程序中，按钮的父tr和您要隐藏的tr之间会有更多的兄弟姐妹。

否则，请使用 next() 而不是 nextUntil()，因为您要隐藏tr是具有按钮的tr中最接近的同级

$(document).ready(function() {
  $('.clickme').click(function() {
    
    $(this).closest('tr').nextUntil('tr.test').slideToggle('slow');
  });
});

Answer 2

使用

.closest('tr') 转到父tr，然后使用 .next('tr') 选择下一个：

$(this).closest('tr').next('tr').slideToggle('slow');

注意：确保没有重复的 id test，并改用公共类。

注2：您使用的nextUntil()也可以使用，但是当不需要时，它会搜索后续元素，next()方法更快，因为它将直接针对下一个元素。

工作片段：

$(document).ready(function() {
  $('.clickme').click(function() {
    $(this).closest('tr').next('tr').slideToggle('slow');
  });
});
