I'm using Javascript and JSONP and want to find-out a user's total badge-count (i'm not using any libraries).

At first I naively added up the badge counts individually, but some user's have no badges. I also want to make sure it keeps working if the API changes to only list badge types the user has or a platinum badge is added.

I can't iterate through them either and userInfo.badge_counts.length is undefined.

What is the best way to do this?

The API (once it's version 1.0*, anyway) won't change. You're concerns are unwarranted.

Just sum the gold, silver, and bronze badges counts you get from /users/{id}.

*And with 0.9 being a release candidate, there almost certainly won't be any changes in badges of all things before 1.0

  • I know, but it makes sense (at least to me) to make it easier to upgrade when a new version does appear. Still, the main problem that prompted this question was that when I do that for some users (such as #999 on SuperUser) that don't have badges, the result I get is "NaN."

  • @Simon - those fields are marked as optional. You'll have to check for presence before summing across them. There are lots of places in the API where such checks are necessary. Jun 26, 2010 at 18:35
