I am new to all of coding and I have a rest point with all of my park polygons, what I want to do is be able to select a park name from a drop down menu and query out and display the single park that is chosen. I believe I have everything set up to query my geometry, now I don't know how to get it to draw the queried feature. right now I have 2 different drop downs. According to my professor i have the 2 selections stored in "selectedParkFeature" and "selectedLayer" variable, and all I have to do now is to draw them on the map. I have researched and I am stuck, please help. I am doing all of this on ArcGIS JavaScript API 3.17.
query("#selectParkName").on('change', function (evt) {
var tempParkName = evt.target.value;
getParkFeature(tempParkName);
});
//function to select the park
function getParkFeature(in_park_name) {
var query = new Query();
query.where = "NAME='" + in_park_name + "'";
query.outFields = ["*"];
park.queryFeatures(query, function (featureSet) {
console.log(featureSet);
selectedParkFeature = featureSet.features[0];
});
}
query("#myPick").on('change', function (evt) {
var tempLayerName = evt.target.value;
chooseLayer(tempLayerName);
});
function chooseLayer(inLyrName) {
selectedLayer = map.getLayer(inLyrName);
var query = new Query();
query.geometry = selectedParkFeature.geometry;
query.outFields = ["*"];
selectedLayer.queryFeatures(query, function (featureSet) {
console.log(featureSet);
//now you can draw these features on the map
});
