Query multiple feature layers

RyanSmith1 — Wed, 23 Jul 2014 19:03:32 GMT

Hi, is it possible to query multiple feature layers using the the .queryFeatures method? I would like to store all results found into a global array which can then be used elsewhere. Is there any sample i could look at for this situation?

Thanks,

Ryan

To store all results in a global array, you probably want to look at dojo deferred

You would batch up the queries and run them - since they run asynchronously, you'd let the deferred manager handle the receipt of responses, which you would store in the global array.

I posted a similar question on Stack Exchange a while ago - the answer there includes a code sample which may help you.
