How to get the coordinate searched from callback function of QueryTask execute

AdeebFarhan — Mon, 15 Jun 2020 20:42:29 GMT

I have a function checkCoverage for a particular x,y coordinate. Which executes a QueryTask. And get the result in a call back function. A Query Object is passed to QueryTask.execute(). The coordinate to search is set in Query as below.

Is there any way to find the coordinate (Point x and y) which was set in Query object from the callback function (reportMyCoverage) result object?

This is required because I trying to run this Check Coverage Function for multiple coordinates.

Check Coverage Function

checkCoverage: function (x, y ) {

var map = mySelfSearch.map;

var geographicPoint = new Point(x, y);

var projectedPoint=webMercatorUtils.geographicToWebMercator(geographicPoint);

var graphic = new Graphic(projectedPoint);

if (mySelfSearch.map.getLayer('coverageCheckGraphics_point') != undefined) { mySelfSearch.map.getLayer('coverageCheckGraphics_point').clear(); }

mySelfSearch.map.getLayer('coverageCheckGraphics_point').add(graphic);

try{

mySelfSearch.map.getLayer('coverageCheckGraphics_point').graphics[0]);

var chkpnt = map.getLayer('coverageCheckGraphics_point').graphics[0].geometry;

var query = new Query();

var fiberCovCompletionFlagCheck = mySelfSearch.fiberCoverageCompletion;

query.geometry = chkpnt;

query.where = " 1=1 ";

query.returnGeometry = true;

query.spatialRelationship = "esriSpatialRelIntersects";

var queryTaskFiber = new QueryTask(mySelfSearch.queryURLFiber);

query.outFields = ['*'];

queryTaskFiber.execute(query, mySelfSearch.reportMyCoverage, function (error) { console.log(getADBDate() + "Error occured in queryTaskFiber.execute " + error.message); });

mySelfSearch.fiberCoverageCompletion=false;

} catch (e) {

console.log("Error occured in check coverage " + e.message);

}

reportMyCoverage: function (result)

reportMyCoverage: function (result) {

var isCovered = result.features.length > 0;

if (isCovered) {

mySelfSearch.fiberCoverage = 'TRUE';

} else {

mySelfSearch.fiberCoverage = 'FALSE';

}

Adeeb,

Sure here is how. This is call JS Closure. You pass the point object to the result function.

queryTaskFiber.execute(query, 
  function(result){
    mySelfSearch.reportMyCoverage(result, chkpnt);
  }, 
  function (error) {
    console.log(getADBDate() + "Error occured in queryTaskFiber.execute  " + error.message); 
  }
);

reportMyCoverage: function (pntGeom, result) {
  var isCovered = result.features.length > 0;
  if (isCovered) {
    console.log(pntGeom);
    mySelfSearch.fiberCoverage = 'TRUE';
  } else {
    mySelfSearch.fiberCoverage = 'FALSE';
  }
},‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
