Replace non-numeric characters with JavaScript?

I use the regular expression /^+(90)[2-5]{1}[0-9]{9}$/ for phone validation, but when someone enters any special characters (such as * - / ( ) - _) in the input, I want to replace the characters with an empty string (remove them). Note that I don't want to replace the +.

How can I do that?

This will remove all non-numeric characters in a given string:

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

D matches anything that isn't a number; d matches a number.

Misread the question. To remove all non-numeric characters except +, do:

myString = myString.replace(/[^d+]/g,);
