simple regex matching help

Hi, I'm trying to match valid names from a list. Valid names can only contain letters, periods ".", commas "," , spaces " ", and must atleast contain 1 letter.

var checkname = /[a-zA-Z]+(\.|,|\s)*/;

but with this regex string, it also matches names that contain letters and numbers. How do I make it to match only what I've mentioned above?
Any help would be appreciated...

Thanks

Hello.

I'm guessing by the example you gave that you also want the name to be valid only when it starts with a letter. Here's one way to go about it:

var checkname = /^[a-zA-Z][a-zA-Z., ]*$/;

This is assuming that the beginning and ending white-space has already been stripped from the variable you're checking against.

Thanks, I completely forgot about the start and end anchors..
