wrapInner(htm|element|fnl)
概述
将每一个匹配的元素的子内容(包括文本节点)用一个HTML结构包裹起来
这个函数的原理是检查提供的第一个元素（它是由所提供的HTML标记代码动态生成的），并在它的代码结构中找到最上层的祖先元素－－这个祖先元素就是包装元素。
参数
htmlStringV1.2
HTML标记代码字符串，用于动态生成元素并包装目标元素
elementElementV1.2
用于包装目标元素的DOM元素
fnFunctionV1.4
生成包裹结构的一个函数
示例
参数html描述:
把所有段落内的每个子内容加粗
jQuery 代码:
$("p").wrapInner("<b></b>");参数elem描述:
把所有段落内的每个子内容加粗
jQuery 代码:
$("p").wrapInner(document.createElement("b"));回调函数 描述:
用原先div的内容作为新div的class，并将每一个元素包裹起来
HTML 代码:
<div class="container"> <div class="inner">Hello</div> <div class="inner">Goodbye</div> </div>
jQuery 代码:
$('.inner').wrapInner(function() {
return '<div class="' + $(this).text() + '" />';
});结果:
<div class="container"> <div class="inner"> <div class="Hello">Hello</div> </div> <div class="inner"> <div class="Goodbye">Goodbye</div> </div> </div>
