Method Details
-
highlight(target){Handle}Since: ArcGIS API for JavaScript 4.4
-
Highlights the given feature(s).
Known Limitations
Currently the highlight method is only supported in a SceneView.
Parameter:optional The feature(s) to highlight.
Returns:Type Description Handle Returns a highlight handler with a remove()
method that can be called to remove the highlight.Example:// highlight feature on click view.on("click", function(event){ view.hitTest(event).then(function(response){ if (response.results.length) { var graphic = response.results.filter(function (result) { return result.graphic.layer === myLayer; })[0].graphic; view.whenLayerView(graphic.layer).then(function(lyrView){ lyrView.highlight(graphic); }); } }); });
-
isFulfilled()
may be used to verify if creating an instance of the class is fulfilled (either resolved or rejected). If it is fulfilled,true
will be returned.Returns:Type Description Boolean Indicates whether creating an instance of the class has been fulfilled (either resolved or rejected).
-
isRejected()
may be used to verify if creating an instance of the class is rejected. If it is rejected,true
will be returned.Returns:Type Description Boolean Indicates whether creating an instance of the class has been rejected.
-
isResolved()
may be used to verify if creating an instance of the class is resolved. If it is resolved,true
will be returned.Returns:Type Description Boolean Indicates whether creating an instance of the class has been resolved.

Since: ArcGIS API for JavaScript 4.6
-
when()
may be leveraged once an instance of the class is created. This method takes two input parameters: acallback
function and anerrback
function. Thecallback
executes when the instance of the class loads. Theerrback
executes if the instance of the class fails to load.Parameters:callback FunctionoptionalThe function to call when the promise resolves.
errback FunctionoptionalThe function to execute when the promise fails.
Returns:Type Description Promise Returns a new promise for the result of callback
that may be used to chain additional functions.Example:// Although this example uses MapView, any class instance that is a promise may use when() in the same way var view = new MapView(); view.when(function(){ // This function will execute once the promise is resolved }, function(error){ // This function will execute if the promise is rejected due to an error });
