I'm a newbie to RegEx, and this particular issue is flummoxing me. This is for use with a JavaScript function.

I need to validate an input so that it matches only these criteria:

  • Letters A-Z (upper and lowercase)
  • Numbers 0-9
  • The following additional characters: space, period (.), comma (,), plus (+), and dash (-)

I can write a pattern easily enough for the first two criteria, but the third one is more difficult. This is the last pattern I managed, but it doesn't seem to work with the test string Farh%%$$+++,

Here's the pattern I'm trying 

[ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789\\+\\.\\,\\s]*$

It's failing in that it's letting characters other than those specified in the text field when submitting the form.

Any help would be greatly appreciated.
