i use query task return points and i was set symbol and infotemple for points, how to how to get id object atribute of point when click symbol?
You can get the ObjectID from a feature by examining its attributes. For example, the following code (a modification of this sample) will put the ObjectID of the features in the console (lines 124 and 133).
