As others have said - this doesn't look like valid HTML - I'm going to assume that you just gave that as an example as this technique can be used to find any type of element.
This should do the trick to locate the body tag - 这应该可以找到身体标签 -
$('div.wrapper').find('body')
When you don't specify in your selector that you are talking about a class . 当你没有在你的选择器中指定你正在谈论一个类. or id # attribute - the whole string will be matched to the type of element. 或id #属性 - 整个字符串将匹配元素的类型。
The same could be done for - 同样可以做 -
-
<img>tags -<img>标签 -
$('div.wrapper').find('img') -
<a>tags -<a>标签 -
$('div.wrapper').find('a') -
<span>tags -<span>标签 -
$('div.wrapper').find('span') - etc... 等等...

Your HTML Markup is off, first of all. 首先，您的HTML标记已关闭。
<body>
<div class="wrapper">
<div class="body">
..
..
</div>
</div>
</body>
Select it with $('div.wrapper div.body') 用$('div.wrapper div.body')选择它

它看起来不像有效的HTML，但试试这个：
$('div.wrapper body')

Surely that HTML isn't correct to have a body tag within a div? 当然，在div中有一个body标签，HTML是不正确的？ Unless it's inside an iframe? 除非它在iframe里面？
However you could use this to select the body tag... 但是你可以使用它来选择body标签......
jQuery("div.wrapper body").whatever();
