Is it possible to pass polygon to query.geometry

veenahosur1 — Mon, 01 Feb 2016 07:53:10 GMT

HI,

i am trying to highlight polygon and corresponding points.so i am trying to do some thing like:

var queryTask = new QueryTask("http://myserver/arcgisserver/rest/services/CRD/CRD2/MapServer/0");

var query = new Query();

query.geometry = event.mapPoint; //your district polygon geometry

query.outFields = ["*"];

query.returnGeometry = true;

//Execute task

queryTask.execute(query, showResults);

function showResults (results) {

var resultItems = [];

var resultCount = results.features.length;

for (var i = 0; i < resultCount; i++) {

var featureAttributes = results.features.attributes;

}

is it possible to pass polygon to query.geometry.if so how to do

Hi Veena,

Here is a JS Fiddle that can help you get started. You can select a polygon and the intersecting points will be selected.

Can you elaborate? How is the user inputting a polygon? i.e. Draw toolbar?
