index: The index of each child to match, starting with the last one (
1
), the stringeven
orodd
, or an equation ( eg.:nth-last-child(even)
,:nth-last-child(4n)
)
Because jQuery's implementation of :nth-
selectors is strictly derived from the CSS specification, the value of n
is "1-indexed", meaning that the counting starts at 1. For other selector expressions such as :eq()
or :even
jQuery follows JavaScript's "0-indexed" counting. Given a single <ul>
containing three <li>
s, $( "li:nth-last-child(1)" )
selects the third, last, <li>
.
Further discussion of this usage can be found in the W3C CSS specification.
