Multiple service areas

MattTenold

Hi everyone,

I new to using the ESRI JS API, and I have a hard time working with arrays and the ESRI ServiceAreaTask.   What I would like to do is allow a user to place multiple points and see a 1 and 2 minute response area around each point.

Here is my code

I keep getting the following warning with Firebug: "Graphic is not defined"  I am confused since I am defining Graphic as new.

Any help would be greatly appreciated.

function mapClickHandler(evt){
      map.graphics.clear(); //clear existing graphics   
     
      //define the symbology used to display the results and input point
      var pointSymbol = new esri.symbol.SimpleMarkerSymbol(
        esri.symbol.SimpleMarkerSymbol.STYLE_DIAMOND,
        20,
        new esri.symbol.SimpleLineSymbol(
          esri.symbol.SimpleLineSymbol.STYLE_SOLID,
          new dojo.Color([88,116,152]),
          2
        ),
        new dojo.Color([88,116,152,0.45])
      );     
   //map.graphics.add(new esri.Graphic(evt.mapPoint, pointSymbol)).getDojoShape().moveToBack();
   //alert(evt.mapPoint.toString());
   var geometry = new esri.geometry.Point(evt.mapPoint.x,evt.mapPoint.y,map.spatialReference);
   var graphic = new Graphic(geometry);
   var inPoint = new array();
   for (var i = 1; i < evt.geometry.length; i++) {
      inPoint.push();
   }
   //alert(evt.inPoint.toString());
      //var inPoint = new esri.geometry.Point(evt.mapPoint.x,evt.mapPoint.y,map.spatialReference);
      //var location = new esri.Graphic(inPoint,pointSymbol);
      //map.graphics.add(location);
     
      var features = [];
      features.push(location);
     
      var facilities = new esri.tasks.FeatureSet();
      facilities.features = features;
      params.facilities = facilities;

      //solve
      serviceAreaTask.solve(params, function(serviceAreaSolveResult){
        var serviceAreaSymbol = new esri.symbol.SimpleFillSymbol(
          esri.symbol.SimpleFillSymbol.STYLE_SOLID, 
          new esri.symbol.SimpleLineSymbol(
            esri.symbol.SimpleLineSymbol.STYLE_SOLID,
            new dojo.Color([232,104,80]),
            2
          ),
          new dojo.Color([232,104,80,0.25])
        );

        dojo.forEach(serviceAreaSolveResult.serviceAreaPolygons,function(serviceArea){
          serviceArea.setSymbol(serviceAreaSymbol);
          map.graphics.add(serviceArea);
        });
       
      }, function(err){
        console.log(err.message);
      });
    }

Thanks

Never mind I got it to work.   It was my fault. Thanks John.
