Strip all non-numeric characters from string in JavaScript

Question

Consider a non-DOM scenario where you\'d want to remove all non-numeric characters from a string using JavaScript/ECMAScript. Any characters that are in range 0 - 9

Answer 1

Use the string's .replace method with a regex of \D, which is a shorthand character class that matches all non-digits:

myString = myString.replace(/\D/g,'');
