返回值:jQueryend()

V1.0概述

回到最近的一个"破坏性"操作之前。即，将匹配的元素列表变为前一次的状态。

如果之前没有破坏性操作，则返回一个空集。所谓的"破坏性"就是指任何改变所匹配的jQuery元素的操作。这包括在 Traversing 中任何返回一个jQuery对象的函数--"add", "andSelf", "children", "filter", "find", "map", "next", "nextAll", "not", "parent", "parents", "prev", "prevAll", "siblings" and "slice"--再加上 Manipulation 中的 "clone"。

示例

描述:

选取所有的p元素，查找并选取span子元素，然后再回过来选取p元素

HTML 代码:

<p><span>Hello</span>,how are you?</p>

jQuery 代码:

$("p").find("span").end()

结果:

[ <p><span>Hello</span> how are you?</p> ]
