Replace values between parentheses using Javascript and Regex

Question

I need to replace the text between two parentheses using Regex in Javascript. For example:

var x = "I need to go (now)";

I need to replace 'now' with 'tomorrow'. I tried this, but it didn't work:

x.replace(/\(now)\b/g, 'tomorrow');

You don't need Regex for such trivial problem. Use String's methods, as @anubhava suggested — hindmost, Aug 06 '15 at 15:27
@hindmost You do not actually know how complex the search is. Perhaps it is a generic "replace something in brackets with something else" more than once in a sentence — mplungjan, Aug 06 '15 at 15:28
@anubhava does that replace all occurrences? I think it replaces only one — netgen, Aug 06 '15 at 15:29

"I need to know (now)".replace(/\(now\)/g, 'tomorrow');

You don't need the \b and you need to escape the second ).

Does that replace all occurrences? – netgen Aug 06 '15 at 15:29
The code in my post will replace all occurrences because of the `g` flag at the end of the regex. Remove it to only replace the first occurrence. – Mike Aug 06 '15 at 15:30
