PopupViewModel | API Reference | ArcGIS Maps SDK for JavaScript 4.31

Provides the logic for the Popup widget, which allows users to view content from feature attributes. Popups enhance web applications by providing users with a simple way to interact with and view attributes in a layer. They play an important role in relaying information to the user, which improves the storytelling capabilities of the application.

Property Details

actions Inherited Property actions Collection<(ActionButton|ActionToggle)>autocast Inherited from FeaturesViewModel Autocasts from Object []

Collection of action or action toggle objects. Each action may be executed by clicking the icon or image symbolizing them. By default, every popup and Features widget has a Zoom To action styled with a magnifying glass icon popupTemplate-zoom-action . When this icon is clicked, the view zooms in four LODs and centers on the selected feature.

You may remove this default action by setting includeDefaultActions to false, or by setting the overwriteActions property to true in a PopupTemplate. The order of each action is the order in which they appear in the actions Collection.

The trigger-action event fires each time an action is clicked.

Actions are defined with the properties listed in the ActionButton or ActionToggle class.

// Defines an action button to zoom out from the selected feature
const zoomOutAction = {
  type: "button",
  // This text is displayed as a tooltip
  title: "Zoom out",
  // The ID by which to reference the action in the event handler
  id: "zoom-out",
  // Sets the icon used to style the action button
  icon: "magnifying-glass-minus"

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle []

Handles marked for removal once the object is destroyed.

groupKey *

optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

clear Inherited Method clear() Inherited from FeaturesViewModel

Removes all promises, features, content, and title.

emit Inherited Method emit(type, event){Boolean} Inherited from FeaturesViewModel Since: ArcGIS Maps SDK for JavaScript 4.5 FeaturesViewModel since 4.27, emit added at 4.5.

Emits an event on the instance. This method should only be used when creating subclasses of this class.

Parameters

type String

The name of the event.

event Object

optional

The event payload.

Returns

Type	Description
Boolean	`true` if a listener was notified

fetchFeatures Inherited Method fetchFeatures(screenPoint, options){Promise<FetchPopupFeaturesResult>} Inherited from FeaturesViewModel Since: ArcGIS Maps SDK for JavaScript 4.15 FeaturesViewModel since 4.27, fetchFeatures added at 4.15.

Use this method to return feature(s) at a given screen location. These features are fetched from all of the LayerViews in the view. In order to use this, a layer must already have an associated PopupTemplate and have its popupEnabled. These features can then be used within a custom Popup, Features, or Feature widget experience. One example could be a custom side panel that displays feature-specific information based on an end user's click location. This method allows a developer the ability to control how the input location is handled, and then subsequently, what to do with the results.

Parameters

screenPoint Object

An object representing a point on the screen. This point can be in either the MapView or SceneView.

Specification

x Number

The x coordinate.

y Number

The y coordinate.

options FetchFeaturesOptions

optional

The options to pass into the fetchFeatures method.

Returns

Type Description

Promise<FetchPopupFeaturesResult> Resolves with the selected hitTest location. In addition, it also returns an array of graphics if the hitTest is performed directly on the view, a single Promise containing an array of all resulting graphics, or an array of objects containing this array of resulting graphics in addition to its associated layerview. Most commonly if accessing all features, use the single promise returned in the result's allGraphicsPromise and call .then() as seen in the example snippet.

Type	Description
Promise<FetchPopupFeaturesResult>	Resolves with the selected `hitTest` location. In addition, it also returns an array of graphics if the `hitTest` is performed directly on the view, a single Promise containing an array of all resulting graphics, or an array of objects containing this array of resulting graphics in addition to its associated layerview. Most commonly if accessing all features, use the single promise returned in the result's allGraphicsPromise and call `.then()` as seen in the example snippet.
