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 then() 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 });
