I have the following regular expression:

/^[0-9]{4,5}$/

Open in new window


This validates that an input field only accepts 4 or 5 digits as the input.  I need to change it to accept either 4, 5 or 6 digits now.  

I tried the following:

/^[0-9]{4,5,6}$/

Open in new window


This did not work.

Any help is appreciated.
Thanks.
