jQuery将div附加到特定的

Question

How do I append a element a specific index of the children elements using jQuery append eg if I have:

<div class=".container">
   <div class="item"><div>
   <div class="item"><div>
   <div class="item"><div>
   <div class="item"><div>
</div>

and I want to append another item between the second and third item?

Answer 1

There are a few options:

$("div.container div.item").eq(2).after($('your html'));

$("div.container div.item:nth-child(3)").after($('your html'));

$($("div.container div.item")[2]).after($('your html'));

The same options, but inserting into the same position using "before":

$("div.container div.item").eq(3).before($('your html'));

$("div.container div.item:nth-child(4)").before($('your html'));

$($("div.container div.item")[3]).before($('your html'));

Answer 2

("div.container div.item:eq(1)").after("<element to insert>")

Answer 3

$('.container').children()[1].append('whatever');
