Regex remove all special characters except numbers

Question

I would like to remove all special characters  except for numbers  from a string  I have been able to get this far  var name   name replace    a-zA-Z            but it seems that it is removing the first number and leaving all of the others    For example   name    collection1234       gt  collection234   or   name    1234567       gt  234567

If you don t mind including the underscore as an allowed character  you could try simply   result   subject replace   W  g         If the underscore must be excluded also  then  result   subject replace    A-Z0-9   ig          Note the case insensitive flag
