wrap(html|element|fn)
概述
把所有匹配的元素用其他元素的结构化标记包裹起来。
这种包装对于在文档中插入额外的结构化标记最有用，而且它不会破坏原始文档的语义品质。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裹元素。当HTML标记代码中的元素包含文本时无法使用这个函数。因此，如果要添加文本应该在包裹完成之后再行添加。
参数
htmlStringV1.0
HTML标记代码字符串，用于动态生成元素并包裹目标元素
elementElementV1.0
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
html参数描述:
把所有的段落用一个新创建的div包裹起来
jQuery 代码:
$("p").wrap("<div class='wrap'></div>");elem参数描述:
用ID是"content"的div将每一个段落包裹起来
jQuery 代码:
$("p").wrap(document.getElementById('content'));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').wrap(function() {
return '<div class="' + $(this).text() + '" />';
});结果:
<div class="container"> <div class="Hello"> <div class="inner">Hello</div> </div> <div class="Goodbye"> <div class="inner">Goodbye</div> </div> </div>
