Nadir,

What does the code look like that you are using to check if the polygon contains the point? Are the point and the Polygon Feature in the same WKID?

dear robert

my code below,

pt = new Point(txtLong, txtLat, map.spatialReference);

queryTask = new esri.tasks.QueryTask(RestServiceUrl + "/4");

query = new esri.tasks.Query();

query.geometry = pt;

// query.spatialRelationship = Query.SPATIAL_REL_INTERSECTS;

query.spatialRelationship = Query.SPATIAL_REL_WITHIN;

i check both query option.but same result.

pls help.

Hi Nadir!

Is this the complete Code? Have you check your require if it's complete?

It seems you are using the legacy-Modul, is that right?

If you check the legacy Documentation for the esri.Task.query your definition should look like this:

query.spatialRelationship = esri.Task.Query.SPATIAL_REL_WITHIN;

Maybe this will do the job.

By the way, I would recommend you to have a close look inside the documentation.

Nadir,

I think Miriam is on the right track here. You are mixing Legacy and AMD in your code and you REALLY need to get out of this habit. If you are not aware what differentiates the two then the simple way to know is if you are using "esri.tasks.QueryTask" instead of just "QueryTask" and it associated require then you are using Legacy. I do not recommend anyone continue using Legacy module as the JS API 4.0 is just about to be released and legacy will NOT be supported. Spend some time reading this blog about AMD

So assuming that you have the require for QueryTask and Query as well as their positional arguments then your code would look like this:

pt = new Point(txtLong, txtLat, map.spatialReference);
queryTask = new QueryTask(RestServiceUrl + "/4");
query = new Query();
query.geometry = pt;

query.spatialRelationship = Query.SPATIAL_REL_WITHIN;
