next选择下一个元素:默认情况下，它不仅选择相同类型的元素.

next chooses the next element: by default it does not only select an element of the same type.

$('#test h2').next();      // selects the p
$('#test h2').next('p');   // selects the p
$('#test h2').next('h2');  // does not select the p

除非提供选择器，否则next 将选择下一个兄弟元素.因此，您可以执行以下操作:

Unless you provide a selector, next will choose the next sibling element. You can therefore do this:

$('#test h2').text('Changed title').next().text('Changed text');
