Property Details

abilities Property abilities Abilitiesautocast Since: ArcGIS Maps SDK for JavaScript 4.21 FeatureViewModel since 4.7, abilities added at 4.21.

Defines the specific abilities that the Feature and Popup widgets should use when querying and displaying its content.

content Property content Content[]|Widget|HTMLElement|Stringreadonly

The content of the feature.

Default Value:null

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

The name of the class. The declared class name is formatted as esri.folder.className.

defaultPopupTemplateEnabled Property defaultPopupTemplateEnabled Boolean Since: ArcGIS Maps SDK for JavaScript 4.11 FeatureViewModel since 4.7, defaultPopupTemplateEnabled added at 4.11.

Enables automatic creation of a popup template for layers that have popups enabled but no popupTemplate defined. Automatic popup templates are supported for layers that support the createPopupTemplate method. (Supported for FeatureLayer, GeoJSONLayer, OGCFeatureLayer, SceneLayer, CSVLayer, PointCloudLayer, StreamLayer, and ImageryLayer).

Starting with version 4.28, date fields are formatted using the short-date-short-time preset dateFormat rather than long-month-day-year in default popup templates created by setting the defaultPopupTemplateEnabled property to true. For example, previously a date that may have appeared as "December 30, 1997" will now appear as "12/30/1997 6:00 PM".

Default Value:false

formattedAttributes Property formattedAttributes Objectreadonly

The formatted attributes calculated from fieldInfo PopupTemplate content. They are obtained from the feature's graphic attribute values and can be read:

globally using the fieldInfos property directly at the root level of the PopupTemplate, or
per an individual content element. This element is defined with a fieldsContent popup element set on the PopupTemplate content property.

Properties: global Object

optional
The formatted attributes specified at the root level of the PopupTemplate using the PopupTemplate.fieldInfos property.

content Object

optional
The formatted attributes for an individual content element. This is derived from the esri/PopupTemplate PopupTemplate, or per an individual content element. This element is defined with a fieldsContent popup element set on the PopupTemplate's content.
Default Value:null

graphic Property graphic Graphic

The Graphic used to represent the feature.

Default Value:null

PopupTemplate.content

Example

let graphic = new Graphic({
  geometry: view.center,
  attributes: {
    "name": "Spruce",
    "family": "Pinaceae",
    "count": 126
  },
  symbol: new SimpleMarkerSymbol({
    style: "square",
    color: "blue",
    size: "8px"
  }),
  popupTemplate: {
    content: [
      {
        // Set popup template content
      }
    ]
  }
});

lastEditInfo Property lastEditInfo Objectreadonly

A read-only property containing metadata regarding the last edit performed on a feature. This object has the following properties:

Properties: user String

User who performed the last edit on a feature.

date String

Date that the edit was performed.

type String

The type of edit that was performed on the feature.

Possible Values:"edit"|"create"

location Property location Point Since: ArcGIS Maps SDK for JavaScript 4.29 FeatureViewModel since 4.7, location added at 4.29.

The Point representing the location of the MapView interaction used to trigger the opening of the widget.

This value should be set when executing Arcade expressions in the Feature widget that expect the $userInput profile variable to have a value.

Default Value:null

See also

Example

view.on("click", (event) => {
  const { mapPoint } = event;
  feature.viewModel.location = mapPoint;
});

map Property map Map Since: ArcGIS Maps SDK for JavaScript 4.11 FeatureViewModel since 4.7, map added at 4.11.

A map is required when the input graphic has a popupTemplate that contains Arcade expressions in ExpressionInfo or ExpressionContent that may use the $map profile variable to access data from layers within a map. Without a map, expressions that use $map will throw an error.

Alternatively, the view property can be used to provide the map instance for this property.

Default Value:null

See also

Example

// The building footprints represent the buildings that intersect a clicked parcel
let buildingFootprints = Intersects($feature, FeatureSetByName($map, "Building Footprints"));

spatialReference Property spatialReference SpatialReference Since: ArcGIS Maps SDK for JavaScript 4.11 FeatureViewModel since 4.7, spatialReference added at 4.11.

The spatial reference used for Arcade operations. This property should be set if executing Arcade expressions that contain geometry functions.

Default Value:null

See also

state Property state Stringreadonly Since: ArcGIS Maps SDK for JavaScript 4.21 FeatureViewModel since 4.7, state added at 4.21.

The view model's state.

Possible Values:"ready"|"disabled"|"error"|"loading"

Default Value:disabled

timeZone Property timeZone String Since: ArcGIS Maps SDK for JavaScript 4.29 FeatureViewModel since 4.7, timeZone added at 4.29.

Dates and times displayed in the widget will be displayed in this time zone. By default this time zone is inherited from MapView.timeZone. When a MapView is not associated with the widget then the property will fallback to the system time zone.

Possible Values

Value	Description
system	Dates and times will be displayed in the timezone of the device or browser.
unknown	Dates and time are not adjusted for any timezone.
Specified IANA timezone	Dates and times will be displayed in the specified IANA time zone. See wikipedia - List of tz database time zones.

title Property title Stringreadonly

The title for the feature.

view Property view MapView|SceneView

A reference to the MapView or SceneView. Set this to link the widget to a specific view.

The FeatureViewModel requires a view if the user expects it to display content in any of the following situations:

The graphic has a popupTemplate containing Arcade expressions in ExpressionInfo or ExpressionContent that may use geometry functions or reference the $map profile variable (i.e. access data from layers within a map).
Content is displayed from the popup template of an aggregate feature (i.e. a cluster or bin).
Values from date and timestamp-offset fields should respect the view's time zone.

waitingForContent Property waitingForContent Booleanreadonly

Indicates whether the feature is currently waiting for all of its content to finish loading.
