Hi everybody,

I'm doing this example https://developers.arcgis.com/en/javascript/jssamples/routetask_closest_facility.html
but I have a problem about the facilities creation.
                facilitiesGraphicsLayer.add(new Graphic(new Point(-13626477, 4549415, map.spatialReference)));
                facilitiesGraphicsLayer.add(new Graphic(new Point(-13625385, 4549659, map.spatialReference)));
                facilitiesGraphicsLayer.add(new Graphic(new Point(-13624374, 4548254, map.spatialReference)));
                facilitiesGraphicsLayer.add(new Graphic(new Point(-13624891, 4548599, map.spatialReference)))


The problem is whenever I create a map with a new different location (like Alabama, New York state...) I have to create a new facilities Point for that map. So can anybody can help me about creating automatically the facilities Point and routes when I make a new different location map and click on it ?

Thank you for your reading time about my topic ! Best wishes for you. :rolleyes:

This worked for me:

facilitiesFeatureLayer = new FeatureLayer("http://YourServerURL/arcgis/rest/services/MapServices/YourMapService/MapServer/0", {
       mode: FeatureLayer.MODE_SNAPSHOT,
       opacity: 0.0   
});

.....

params = new ClosestFacilityParameters();
params.defaultCutoff= 500.0;
params.returnIncidents=false;
params.returnRoutes=true;
params.returnDirections=true;
params.returnFacilities=true;

....

var facilities = new FeatureSet();
facilities.features = facilitiesFeatureLayer.graphics; 
params.facilities = facilities;
params.outSpatialReference = map.spatialReference;

Let me know if you need to see additional code.

Hope that helps.
