Scipts Hangs when executing query

vinayb — Sat, 11 Dec 2021 13:57:06 GMT

HI

I have a service which is deployed in my local arcgis server which has world country boundries , when i load just a map it works fine but when i add a query task it hangs , the whole browser system and system hangs can anybody tell what could be the reason , i checked in firebug the query response is in milliseconds still it hangs but there are some other request like http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer/tile/2/0/3 and many more of these which take hell lot of time , please let me know what could the issue.Below is query code

var queryTask = new esri.tasks.QueryTask(url);
      var query = new esri.tasks.Query();
      query.returnGeometry = true;
                        query.where = "COUNTRY='India'";
dojo.connect(queryTask, "onComplete", function(featureSet) {
          //alert('calling queryTask'+featureSet);
       //map.graphics.clear();
        try{
         /*var sfs = new SimpleFillSymbol(SimpleFillSymbol.STYLE_FORWARD_DIAGONAL, new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color([255, 0, 0]), 2), new Color([255, 255, 0, 0.5]));
         alert('somethign');*/
         
         var symbol = new SimpleFillSymbol(
          SimpleFillSymbol.STYLE_SOLID,
          new SimpleLineSymbol(
            SimpleLineSymbol.STYLE_SOLID,
            new Color([255,0,0,0.65]), 2
          ),
          new Color([255,0,0,0.35])
           );

         
         //QueryTask returns a featureSet.  Loop through features in the featureSet and add them to the map.
         dojo.forEach(featureSet.features,function(feature){
          alert('feature'+feature);
          var graphic = feature;
          graphic.setSymbol(symbol);
          alert("infoTemplate"+infoTemplate);
          graphic.setInfoTemplate(infoTemplate);
          alert("graphic"+graphic);
          alert("map.graphics"+map.graphics);
          map.graphics.add(graphic);
       
        });
       }catch(e){
         alert("e"+e);
       }
      });
     queryTask.execute(query);

initialization of map

var bounds = new Extent({
            "xmin":-16045622,
            "ymin":-811556,
            "xmax":7297718,
            "ymax":11142818,
            "spatialReference":{"wkid":102100}
          });
           map = new esri.Map("map", { 
          basemap: "streets", 
          zoom: 2 
        }); 
          var url = "http://10.32.9.106:6080/arcgis/rest/services/Demo/World_Countries_v1/MapServer/0";
          var fl = new FeatureLayer(url, {
            id: "world-regions"
            //infoTemplate: template
          });

Have you tried directly querying the rest service in browser?
http://10.32.9.106:6080/arcgis/rest/services/Demo/World_Countries_v1/MapServer/0/query

If not, try it and check if you are getting the result in browser directly.

In your code are you getting into the onComplete function? Means where is your process actually hanging?
Also , add error handling event to querytask
dojo.connect(queryTask, "onError", function(error) {
alert(error.description);
});

This may be due to the different projection system of your map. Do one thing set the coordinate system 102100 in you MXD data frame properties. And re-publish your service

Currently we have WGS84 is this a problem

Regarding your query hangs,have you added your geometry service and your service url in your proxy.config?
