Looks like you want to execute identify on multiple map services. What you need here is dojo.deferredList
Below extracts from one of my old project where i have used deferred list for wiring multiple selection operation. You should be able to build up on this.
// 1. Populate your deferred array
var deferredQuery = this._queryTask.execute(args.spatialQuery);
this._deferredQueryArray[this._deferredQueryArray.length] = deferredQuery;
// 2. Hook up your deferred list then action
if (this._deferredQueryArray.length > 0) {
this._deferredQueryList = new dojo.DeferredList(this._deferredQueryArray);
this._deferredQueryList.then(
dojo.hitch(this, this.handleDeferredResults, extent, businessData, queryLayerMap),
dojo.hitch(this, function (err) {
alert(err);
}));
}
// 3. Handle your deferred
handleDeferredResults: function (extent, businessData, queryLayerFieldMaps, results) {
console.log("Entered Method: " + arguments.callee.nom);
if (results.length != queryLayerFieldMaps.length) {
alert("Somethings not right, contact application support. Business data and spatial results don't match");
}
this.removeFiredFromDeferred(this._deferredQueryArray);
// Do whatever you would normally do with your identify result.
}
// 4. Clear Your fired deferred from your deferred list
removeFiredFromDeferred: function (deferredArray) {
for (var idx = deferredArray.length -1; idx >= 0; idx--) {
if (deferredArray[idx].fired > -1) {
deferredArray.splice(idx, 1);
}
}
}
