feature

Question asked by anjelinaponkerat on Jan 30, 2018

I,m going to change portal item in edit sample and add feature layer, but no result: 

 

var MyFeature = new FeatureLayer({
url: "https://localhost:6080/arcgis/rest/services/Texass_Layer/FeatureServer/4",

visible:true,
});

 

How to replace feature layer instead of portal item in this sample?:
