返回值:jQueryreplaceAll(selector)

概述

用匹配的元素替换掉所有 selector匹配到的元素。

在jQuery 1.3.2中,appendTo, prependTo, insertBefore, insertAfter, 和 replaceAll这个几个方法成为一个破坏性操作,要选择先前选中的元素,需要使用end()方法,参见 appendTo 方法的例二。

参数

selector选择器

用于查找所要被替换的元素

示例

描述:

把所有的段落标记替换成加粗标记

HTML 代码:
<p>Hello</p><p>cruel</p><p>World</p>
jQuery 代码:
$("<b>Paragraph. </b>").replaceAll("p");
结果:
<b>Paragraph. </b><b>Paragraph. </b><b>Paragraph. </b>
