get all numbers in a string and push to an array (javascript)

Question

So if I had the following string:

\'(01) Kyle Hall - Osc (04) Cygnus - Artereole (07) Forgemasters - Metalic (10) The Todd Terry Project - Back to the Beat (14)          


        

Answer 1

Use a regular expression:

var numbers = str.match(/\d+/g);

This will result in ["01", "04", "07", "10", "14"] (array of strings). If the type of the elements matters to you you can follow up with .map(Number) to convert to numbers:

var reallyNumbers = str.match(/\d+/g).map(Number);

which will result in [1, 4, 7, 10, 14].

Note that map is not available in IE earlier than version 9, so depending on your compat requirements you might need a polyfill. There's a ready-made one on MDN.
