javascript string split negative

Question

Is it possible to use string split in javascript to get the last element in the array that is produced.

For example, im sure in php you can do the same and use a negative limit value to get the last item i.e. -1 or the last two items -2 etc.

Answer 1

You can use slice on the result array you get from split:

"Lorem ipsum dolor sit amet consectetur".split(/ /).slice(-2) // returns ["amet", "consectetur"]

Answer 2

There's a pop() method that removes and returns the last element of an array:

"/path/to/somefile.jpg".split("/").pop();
// -> "somefile.jpg"

As Gumbo mentioned, slice() will allow you to select a range of array elements.

Answer 3

pop and splice are what you are after

var a = "1,2,3,4,5";
var b = a.split(/,/g).pop();
var a1 = a.split(/,/g);
var c = a1.splice(a1.length-2,a1.length);
var d = a.split(/,/g).splice(-2);
