Javascript how to ascertain if it is a comma delimited list?

Question

I'm curious, how would you test a string and say "yep, that is a comma delimited list!" I'm not so worried about the 'comma delimited' part more that this string has more than one item in it?

Thanks, R.

Answer 1

How about:

stringObject.indexOf(",") >= 0

Answer 2

To check if the string has more than one item, try something like:

str.split(",").length > 1

... although, as suggested in a comment, correct parsing is likely to be bit more complicated than this for the general case.

Edit:

whoops, misread language as Java - sorry.
