Split a given string and get last split value

Question

I have a string like

count-contribute-1
count-contribute-11
count-contribute-1111

Here I want to split the string and get the last split value (i.e 1 , 11, 1111);

How can I do it?

Though not a good solution, just to add there is a way like `var string = "count-contribute-1"; string.substring(string.lastIndexOf('-')+1, string.length)` — Praveen, Apr 01 '14 at 12:02

split() on - and pop() of the last value

string.split('-').pop()

Use .pop() to get the last item from the array created by .split()

"count-contribute-1".split('-').pop();

Also you can get last part of numbers using regular expression. Like this:

s = "count-contribute-111"
s.match(/\d+$/)
//return "111"

It doesn't matter what separator you use.

s = "count-contribute-+*%111"
s.match(/\d+$/)
//return "111"
