我如何能够从美元中获取一个子要素?
因此,例如,我如何把这个目标中的一个跨段内容作为目标?
您可使用。 方法:
$(this).find("span");
这将找到所有<代码>span元素的后代,这些元素是<代码>this中提及的要素的后代。
如果你只关心直接儿童,你可使用http://api.jquery.com/children/>children。 相反:
$(this).children("span");
或者,您可使用<代码>该作为选择人的背景:
$("span", this);
如果<代码>该是含有一套纤维元素的 j子(即<代码>span不是后代),则还需要另一种解决办法。 在此情况下,你需要filter:
$(this).filter("span");
