javascript - Regex for getting text between the last brackets ()

Question

I want to extract the text between the last () using javascript

For example

var someText="don't extract(value_a) but extract(value_b)";
alert(someText.match(regex));

The result should be

value_b

Thanks for the help

Try this

(([^)]*))[^(]*$

See it here on regexr

var someText="don't extract(value_a) but extract(value_b)";
alert(someText.match(/(([^)]*))[^(]*$/)[1]);

The part inside the brackets is stored in capture group 1, therefor you need to use match()[1] to access the result.
