Removing Numbers from a String using Javascript

\d matches any number, so you want to replace them with an empty string:

string.replace(/\d+/g, '')

I've used the + modifier here so that it will match all adjacent numbers in one go, and hence require less replacing. The g at the end is a flag which means "global" and it means that it will replace ALL matches it finds, not just the first one.

Just paste this into your address bar to try it out:

javascript:alert('abc123def456ghi'.replace(/\d+/g,''))

\d indicates a character in the range 0-9, and the + indicates one or more; so \d+ matches one or more digits. The g is necessary to indicate global matching, as opposed to quitting after the first match (the default behavior).
