closest facility service does not work

NadavDoron — Sun, 12 Dec 2021 01:10:42 GMT

Hi all,

I used thr arcgis api help to create a Closest Facility script.

Find closest facilities | ArcGIS API for JavaScript 3.25

I copied almost the entire code, just changed the facilities and the spatial reference.

I uploaded my network analysis service to my server and it does not work.

Nothing i do make it works. I tried to check if the code from the help section works without my changes but apparently i cant connect the service from my PC, but it does work from the link

https://developers.arcgis.com/javascript/3/samples/routetask_closest_facility/

the log in the script is me trying to see where it went wrong, it seems like the

routeGraphicLayer.on("mouse-over", function(evt){
            console.log("ok4.3");
          //clear existing directions and highlight symbol
          map.graphics.clear();
          dom.byId("directionsDiv").innerHTML= "Hover over the route to view directions";
          console.log("ok4.5");
          var highlightSymbol = new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color([0,255,255],0.25), 4.5);
          var highlightGraphic = new Graphic(evt.graphic.geometry,highlightSymbol);
          console.log("ok5");
          map.graphics.add(highlightGraphic);
          dom.byId("directionsDiv").innerHTML = esriLang.substitute(evt.graphic.attributes,"${*}");
            console.log("ok6");
        });‍‍‍‍‍‍‍‍‍‍‍‍‍

and the

//solve 
        closestFacilityTask.solve(params, function(solveResult){
          console.log("ok7");
          array.forEach(solveResult.routes, function(route, index){
            //build an array of route info
            var attr = array.map(solveResult.directions[index].features, function(feature){
              return feature.attributes.text;
            });
            var infoTemplate = new InfoTemplate("Attributes", "${*}");
            console.log("ok");
            route.setInfoTemplate(infoTemplate);
            route.setAttributes(attr);
            
            routeGraphicLayer.add(route);
            dom.byId("directionsDiv").innerHTML = "Hover over the route to view directions";
          });
          console.log("ok??");
          //display any messages
          if(solveResult.messages.length > 0){
            dom.byId("directionsDiv").innerHTML = "<b>Error:</b> " + solveResult.messages[0];
          }      
        });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

does not work at all.

can someone maybe point me for what i`m doing wrong?

thanx

Hi,

you are using defaultCutoff value set to 7.0, while relying on the Length impedance attribute which is in meters, i.e. you are limiting the CF solver to search for facilities within 7m radius.

Increase the defaultCutoff value and keep debugging, pay close attention to the HTTP responses which come from the server - they contain a lot of valuable information.

Hope this helps.
