get the second to last item of an array?

Question

How can I get the last second item in an array?

For instance,

var fragment = '/news/article-1/' var array_fragment = fragment.split('/'); var pg_url = $(array_fragment).last()[0]; 

This returns an empty value. But I want to get article-1

Thanks.

Answer 1

Not everything has to be done using jQuery.

In plain old javascript you can do:

var pg_url = array_fragment[array_fragment.length - 2] 

Easier and faster :)

Looks like you can also use Javascript's slice method:

var path = 'a/b/c/d'; path.split('/').slice(-2, -1)[0]; // c 

You can also think of "second to last element in the array" as "second element of the array reversed":

var path = 'a/b/c/d'; path.split('/').reverse()[1]; // c
