Features not found with query.geometry

Hello,

Im trying to make a query with the map.onclick to get the features founded around the click.

I have added 2 featurelayers that have some values that i want to get when the user clicks to make another analysis.

The problem that now im having is that even if i make a polygon to search for any value, my featureSet doesnt give me any.

My code is:

function clickSearch(mapPoint){

var rectangle = new esri.geometry.Polygon(new esri.SpatialReference(mapPoint.spatialReference.wkid));

rectangulo.addRing(createRectangle(mapPoint,20));

console.log(rectangulo);

var queryTask = new esri.tasks.QueryTask(layers.read_layer_interr_sed());

var query = new esri.tasks.Query;

query.spatialRelationship=esri.tasks.Query.SPATIAL_REL_CONTAINS;

query.geometry = rectangulo;

query.outFields=['*'];

query.returnGeometry = true;

queryTask.execute(query,(featureSet)=>{

console.log("found something here...what is it?");

if(featureSet.features.length!=0){

console.log(featureSet.features);

}else console.log("nothing");

},(error)=>{

console.log("no encontre na" , error);

});

}

function createRectangle(mapPoint,delta){

var arrayOfPoints = [];

arrayOfPoints[0] = new esri.geometry.Point(mapPoint.x-delta,mapPoint.y-delta,mapPoint.spatialReference);

arrayOfPoints[1] = new esri.geometry.Point(mapPoint.x-delta,mapPoint.y+delta,mapPoint.spatialReference);

arrayOfPoints[2] = new esri.geometry.Point(mapPoint.x+delta,mapPoint.y+delta,mapPoint.spatialReference);

arrayOfPoints[3] = new esri.geometry.Point(mapPoint.x+delta,mapPoint.y-delta,mapPoint.spatialReference);

arrayOfPoints[4] = new esri.geometry.Point(mapPoint.x-delta,mapPoint.y-delta,mapPoint.spatialReference);

return arrayOfPoints;

}

Note:

Im not using require to load the modules.

Im programming with ReactJS, webpack server and i just installed the api in that server.

I have been used all the elements for the api in this way:

Example for featureLayer.

var myDynamicSedLayer = new esri.layers.FeatureLayer(layers.read_layer_interr_sed(),{

mode: esri.layers.FeatureLayer.MODE_SNAPSHOT,

infoTemplate: myinfotemplate.getSubFailure(),

outFields: ["*"]

});

Anyone knows what could be happening? or any example doing this.

I already search about it in the sample api.

Thanks in advice.

Evelyn,

You have seriously limited the number of people that will be able to help you (probably by 95% or more) now that you have chosen to use react instead of vanilla javascript, just FYI.

Are you sure you need SPATIAL_REL_CONTAINS and not SPATIAL_REL_INTERSECTS?

Well, im using the legacy side and not amd to play with reactjs, so how in the samples some of them are with AMD and legacy code, i choose legacy.

Well now i think i fix part of my problem doing this:

myDynamicLayer1.on("click",(event)=>{

// console.log(event.graphic.attributes);

});

In this way i will be able to get any attribute that im looking for the click and then using it to more complex analysis or queries.

Thanks for your response.
