I'm trying to insert an li element into a specific index on a ul element using jQuery. I only seem to be able to insert an element on the end of the list. I am very new to jQuery, so I may just not be thinking properly.
Try something like this:
$("#thelist li").eq(3).after("<li>A new item</li>");
eq function, you can get a specific index of the elements retrieved...then, insert the new list item after it.
In the above function, I am inserting a new item at position 4 (index 3).
More info about the function at the jQuery Docs
