Question

I want to extract this “SD” from text “SouthDacota (SD)” in Javascript. I am newbie to regex in js and wanted to know if any one has any ideas.

Answer 1

The simplest regex would match the parentheses, and in between two upper-case letters. In addition you can “capture” the two letters (with unescaped parentheses), so you can retrieve them without the parentheses:

var regex = /\(([A-Z]{2})\)/;
var matches = inputString.match(regex);
var stateCode = matches[1];

But you should really read up on some basics.
