Is there a simple call from arcgis javascript api 4.x to delete all records from a feature class

Jay,

This is the only way I know how.

featureLayer.queryFeatures().then(function(results){

featureLayer.applyEdits({deleteFeatures: results.features});

});

Is there a way to get an alert when the applyEdits is completed or successful? Want to verify its done and then write to the same FC.

Jay,

Sure, applyEdits returns a promise.

featureLayer.queryFeatures().then(function(results){
  featureLayer.applyEdits({deleteFeatures: results.features}).then(results){
    //do something here
  }
});‍‍‍‍‍

hmmmm..

I added a ; at the end of appyEdits but no go...

featureLayer.queryFeatures().then(function(results){
  featureLayer.applyEdits({deleteFeatures: results.features}).then(results){
    //do something here
  };
});‍‍‍‍‍‍‍‍‍‍

Jay, sorry for the bad code I forgot the function part.

featureLayer.queryFeatures().then(function(results){
  featureLayer.applyEdits({deleteFeatures: results.features}).then(function(results2){
    //do something here
  });
});‍‍‍‍‍‍‍‍‍‍

think I got it with this

featureLayer.queryFeatures().then(function (results) {
  featureLayer.applyEdits({ deleteFeatures: results.features }).then(function (results) {
         alert("Im done and now building the multipart features");
  });
});‍‍‍‍‍
