如何使用jquery删除子元素和空格？

我有以下内容:

<div class="sectionA"> <p>sfadfafdafdafdaf</p>  </div>

如果我这样做:

$(".sectionA *").remove();

我明白了:

<div class="sectionA">   </div>

删除 <p> 后如何删除空格子元素？

Answer 1

您需要的是.empty()方法，它的作用正是您所描述的:

This method removes not only child (and other descendant) elements, but also any text within the set of matched elements. This is because, according to the DOM specification, any string of text within an element is considered a child node of that element.

示例:

 $(".sectionA").empty();
