How to convert PHP regex to JavaScript regex

Question

I am currently porting my web app codes from PHP to JS.

I am having an issue with this regex. from PHP

/\(\d*\)|\/\(P\)\//

used like this

preg_replace('/\(\d*\)|\/\(P\)\//', '', $string);

how can I convert this to work on JS ?

str.replace();

Thank you in advance

RegExp is a native feature on Javascript, so you don't need the quotes, just /^$/.test("string"). — Wesley Schleumer de Góes, May 6 '13 at 12:46
Drop the appostrophes and at a /g flag if you want to perform a global regex! ;) — Tim, May 6 '13 at 12:47

Nothing really special. PHP regex syntax is very much the same as in JavaScript:

str = str.replace(/\(\d*\)|\/\(P\)\//g, "");

You can find more information about regular expressions in JavaScript in this manual from MDN: https://developer.mozilla.org/en-US/docs/JavaScript/Guide/Regular_Expressions.

yes, nothing really special other than the /g flag. thank you! – beeant May 6 '13 at 16:32

The /s flag is valid PHP but not JS. – Wyatt8740 Jun 16 at 14:15
