Chris,
Here is the actual JSON I was returning, and then using Object.values(
jsonarray.VidID)[i], etc, etc to grab the values:
{"VidPathStr":{"1":"anotherpath","2":"somepath"},"VidDescrip":{"1":"another
description","2":"some description"},"VidID":{"1":3473,"2":3472}}
Sorry for the confusion earlier. (which do you think is a better/ faster
structure to access -- the array of hashes, or this JSON above?). Your
thoughts?
