How do I append a element a specific index of the children elements using jQuery append e.g. 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?
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')); 
eq() method instead of the non-CSS-standard (and hence less efficient) :eq selector. However, be careful with :nth-child; unlike eq() and most of the rest of everything, its indices are 1-based (argh).("div.container div.item:eq(1)").after("<element to insert>")
$('.container').children()[1].append('whatever'); 
class=".container"is a typo? It's valid to have.in a class name, but not something you'd generally want to do.
