This sample demonstrates that you can query data from a map service without displaying the service. Most map services contain datasets with attribute information that can be queried and displayed in a simple list or table. This sample queries for colleges and universities in the United States, then displays a list of attribute information about that school.
The code creates a QueryTask along with a Query that is used as input to the task.
Notice that the query.returnGeometry is set to false because the results won't be displayed on a map. The outFields determine which fields in the layer will be queried.
When you click the Get Details button, the execute function is called. The query task searches based on a SQL where clause, using "query.where".
