把所有匹配的元素插入到另一个、指定的元素元素集合的后面。

实际上，使用这个方法是颠倒了常规的$(A).after(B)的操作，即不是把B插入到A后面，而是把A插入到B后面。

返回值:jQuery

参数:

• expr (String): 用于匹配元素的jQuery表达式

示例:

与 $("#foo").after("p")相同

$("p").insertAfter("#foo"); 

HTML 代码:

<p>I would like to say: </p><div   id="foo">Hello</div>

结果:

<div id="foo">Hello</div><p>I would like to   say: </p>

Insert all of the matched elements after another, specified, set of elements. This operation is, essentially, the reverse of doing a regular $(A).after(B), in that instead of inserting B after A, you're inserting A after B.

Return value: jQuery
Parameters:

• content (<Content>): Content to insert the selected element after.

Example:

Same as $("#foo").after("p")

 $("p").insertAfter("#foo");  

 <p>I would like to say: </p><div id="foo">Hello</div>  

Result:

 <div id="foo">Hello</div><p>I would like to say: </p>
