Removing Numbers from a String using Javascript

Question

How do I remove numbers from a string using Javascript?

I am not very good with regex at all but I think I can use with replace to achieve the above?

Answer 1

\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.

Answer 2

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).
