String manipulation - getting value after the last position of a char

Question

How I can get the value after last char(. ; + _ etc.): e.g.

string.name+org.com

I want to get "com". Is there any function in jQuery?

Answer 1

Use lastIndexOf and substr to find the character and get the part of the string after it:

var extension = name.substr(name.lastIndexOf(".") + 1);
