functions queryTask1.execute(query1, showResults) return of type point(only one point), how are getting this point and pass to functions centerAndZoom(point, lever).

this is my code

queryTask1.execute(query1, showResults);

function showResults(featureSet) {

//remove all graphics on the maps graphics layer

myMap.graphics.clear();

//Performance enhancer - assign featureSet array to a single variable.

var resultFeatures = featureSet.features;

//Loop through each feature returned

for (var i = 0, il = resultFeatures.length; i < il; i++) {

//Get the current feature from the featureSet.

//Feature is a graphic

var graphic = resultFeatures;

graphic.setSymbol(symbol1);

//Set the infoTemplate.

graphic.setInfoTemplate(infoTemplate);

//Add graphic to the map graphics layer.

myMap.graphics.add(graphic);

}

map.centerAndZoom(???, ????);

}

Hi,

you can try the following. It is not tested, but should work. It zooms to the first found feature.

queryTask1.execute(query1, showResults);
           


              function showResults(featureSet) {


                  //remove all graphics on the maps graphics layer
                  myMap.graphics.clear();


                  //Performance enhancer - assign featureSet array to a single variable.
                  var resultFeatures = featureSet.features;


                  //Loop through each feature returned
                  for (var i = 0, il = resultFeatures.length; i < il; i++) {
                      //Get the current feature from the featureSet.
                      //Feature is a graphic
                      var graphic = resultFeatures;
                      graphic.setSymbol(symbol1);


                      //Set the infoTemplate.
                      graphic.setInfoTemplate(infoTemplate);


                      //Add graphic to the map graphics layer.
                      myMap.graphics.add(graphic);
                  }

                  if (resultFeatures[1] !== undefined) {
                       myMap.centerAndZoom(resultFeatures[1].geometry, 12);
                  }
         

              }
