jQuery - change index of list item

Question

I am trying to change the index of a list item in jquery by doing the following:

 $(this).index(2);

This does not appear to work correctly.

Is the only way to achieve this by using insertBefore/insertAfter?

Answer 1

index() simply returns the index, it does not set it, so you have to use a method that actually changes the DOM to move the element around.

$(this).siblings().eq(1).after(this);
