We worked this out in the IRC room but I wanted to post the answer
here in case someone else found this thread wondering the same thing
(sorry for the chatlog transcript, but I didn't want to misrepresent
what was said):
<kurrik>
the response of that will be an object like { "<user id>" : <key,value
data> }
if the user doesn't have any data, I don't believe that they will show
up in that object
so if nobody has that data, then you should get { } back
<PSobota>
ok.. would that object have any name or it's a dynamically created
object?
<kurrik>
just dynamically created - should be what you get out of the getData()
call
if you set data, you should see something in there
<PSobota>
{ "<user id>" : <key,value data> } is this a dictionary of
dictionaries? what would be this called?
<kurrik>
you can think of it that way
in js, it's all just "objects"
but objects <==> dictionaries for the most part
<PSobota>
i am looking for a way to test whether that has nothing inside.. but
looks like js doesn't have a dictionary syntax
like.. have i gotten {} back? init the data to some string
<kurrik>
I see
hm, I'm actually surprised that I wasn't able to find a better way to
do this
assuming the response is called "obj"
var keys = 0;
for (var i in obj) if (obj.hasOwnProperty(i)) keys++;
if (keys == 0) {
<init the data>
}
