Get text between two rounded brackets

Question

How can I retrieve the word my from between the two rounded brackets in the following sentence using a regex in JavaScript?

"This is (my) simple text"

Answer 1

console.log(    "This is (my) simple text".match(/\(([^)]+)\)/)[1]  );

\( being opening brace, ( — start of subexpression, [^)]+ — anything but closing parenthesis one or more times (you may want to replace + with *), ) — end of subexpression, \) — closing brace. The match() returns an array ["(my)","my"] from which the second element is extracted.

Answer 2

var txt = "This is (my) simple text"; re = /\((.*)\)/; console.log(txt.match(re)[1]);​
