Hi all,

I'm new to JavaScript and am having some problems creating the exact (simple!) regular expression I need. I need to validate a form field to ensure that all words are separated by commas. For example:

word1, word2, word3
or
word1,word2, word3
etc... (note there is no comma after the last word)

So far, my regular expression is able to test for one word, random spaces and the comma, but I'm not sure how to extend this to an arbitrary number of words. So far I've got:

/\w+\s*,{0,1}/

Any help here would be really appreciated!!

Jill
