FeatureLayer selectFeatures does not return "features" and "method"

PitersonPaulgek

Hi,

Version 3.17.

We surprised that FeatureLayer selectFeatures() method does not return "features" and "method" - just Array of objects.

And help is not correct

FeatureLayer | API Reference | ArcGIS API for JavaScript 3.18

That means there is a difference to use QueryTask.execute() or FeatureLayer.selectFeatures().

Should we use 3.18?

Any help please.

You are right.

Could we do it in

function initFunctionality() {
var query2 = new Query();
query2.outFields = ["*"];
query2.where = "OBJECTID < 5";

censusBlockPointsLayer.selectFeatures(query2, FeatureLayer.SELECTION_NEW, function (featureSet) {
console.info(featureSet);
});

...

};

The print in console is the same: Array of Objects

What is the point in doing a selection inside the response of another selection. Also by adding that, you would be creating an infinite loop in your code, because you are executing a selection inside the selection complete handler event.

Robert,

Thank you for the response.

I see.

Please try this

censusBlockPointsLayer.on("selection-complete", function(evt) {
var query = new Query();
query.outFields = ["*"];
query.where = "OBJECTID < 5";

censusBlockPointsLayer.selectFeatures(query, FeatureLayer.SELECTION_NEW, function (featureSet) {
console.info(featureSet);
});
//console.info(evt);
var totalPopulation = sumPopulation(censusBlockPointsLayer.getSelectedFeatures());
var r = "";
r = "<b>The total Census Block population within the drive time polygon is <i>" + totalPopulation + "</i>.</b>";
dom.byId('messages').innerHTML = r;
});

Piterson,

Not sure how your code is handling the FeatureLayer.selectFeatures but this sample does return feature and method just fine (I just added a console.info(evt)):
