Popup | API Reference | ArcGIS Maps SDK for JavaScript 4.32

Overview

The Popup widget 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.

Loading the Popup

At version 4.27, the view's default popup is loaded on demand when popupEnabled is set to true (which is the default), when the openPopup() method is called, or when some widgets need the popup, such as Search. Please see the read more section below for details on how to manually load the popup or take advantage of the API lazy loading.

The Popup class can be loaded when the View is instantiated, however, this does not take advantage of the performance improvements of lazily loading the popup.

// Create a new MapView
const view = new MapView({
// set the popup property to a new instance of Popup
  popup: new Popup(...)
});

To utilize the performance improvements and the API automatically lazy loading the popup:

Set options/properties on the view's popup:

const view = MapView({
  popup: {
    dockEnabled: true,
    dockOptions: {
      position: true,
      ...
    }
  }
});

Use popupEnabled to prevent the popup appearing when the user clicks the view.

// The popup doesn't show for features on selection, but will on Search results and when `openPopup()` is called.
view.popupEnabled = false;

Use openPopup() instead of open() and closePopup() instead of close().

// A deprecation warning is prompted if the popup isn't created
// and calls view.openPopup() or view.closePopup() respectively under the hood.
view.popup.open(...);
view.popup.close(...);

// Opens or closes the popup on the View.
view.openPopup(...);
view.closePopup(...);

Use reactiveUtils to watch properties on the popup and its view model instead of the watch() method.

// This will throw an error that watch() is not a method
// since the popup hasn't been created yet.
view.popup.watch("selectedFeature", ...)

// Call reactiveUtils.watch() on popup properties with optional chaining.
reactiveUtils.watch(() => view.popup?.selectedFeature, ...);

Use the reactiveUtils.when() method to check when the popup instance is created. Once its created, then it's properties or methods can be accessed and called.

// This will throw an error that actions is not a property.
view.popup.actions.push(...);

// Wait for the popup to load before accessing properties.
reactiveUtils.when(() => view.popup?.actions, ()=>{
  view.popup.actions.push(...);
});

Popup UI

All Views contain a default popup. This popup can display generic content, which is set in its title and content properties. When content is set directly on the Popup instance it is not tied to a specific feature or layer.

In the image above, the text "Marriage in New York County Census Tract 8" is the popup's title. The remaining text is its content. A dock button popup-dock-btn may also be available in the top right corner of the popup. This allows the user to dock the popup to one of the sides or corners of the view. The options for docking may be set in the dockOptions property.

Popups can also contain actions that act like buttons, which execute a function defined by the developer when clicked. By default, every popup has a "Zoom to" action popupTemplate-zoom-action that allows users to zoom to the selected feature. See the actions property for information about adding custom actions to a popup.

The Popup widget is tied to the View, whether it's docked or anchored to the selected feature. If wanting to utilize the Popup functionality outside of the View, the Features widget can be used to display the same content in its own container that's not tied to the View.

Popup and PopupTemplate

PopupTemplate is closely related to Popup, but is more specific to layers and graphics. It allows you to define custom titles and content templates based on the source of the selected feature. When a layer or a graphic has a defined PopupTemplate, the popup will display the content defined in the PopupTemplate when the feature is clicked. The content may contain field values from the attributes of the selected feature.

Custom PopupTemplates may also be assigned directly to a popup by setting graphics on the features property. For more information about Popup and how it relates to PopupTemplate see the samples listed below.

Property Details

actions Property actions Collection<(ActionButton|ActionToggle)>autocast 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, popups have 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 classes.

The ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use case when working with widgets.

Examples

// Create the HTML div element programmatically at runtime and set to the widget's container
const basemapGallery = new BasemapGallery({
  view: view,
  container: document.createElement("div")
});

// Add the widget to the top-right corner of the view

See also

Example

// This sets generic instructions in the popup that will always be displayed
// unless it is overridden by a PopupTemplate
view.popup.content = "Click a feature on the map to view its attributes";

currentDockPosition Property currentDockPosition String |null |undefinedreadonly

Dock position in the View.

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.7 Accessor since 4.0, declaredClass added at 4.7.

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 Popup since 4.0, 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, ImageryLayer, and VoxelLayer).

Starting with version 4.12, PopupTemplate content can no longer be set using a wildcard, e.g. *. Instead, set the defaultPopupTemplateEnabled property to true.
Starting with 4.16, the default popup has been improved to no longer display system fields that do not hold significant value, e.g. Shape__Area and Shape__Length are two fields that no longer display.
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

dockEnabled Property dockEnabled Boolean

Indicates whether the placement of the popup is docked to the side of the view.

Docking the popup allows for a better user experience, particularly when opening popups in apps on mobile devices. When a popup is "dockEnabled" it means the popup no longer points to the selected feature or the location assigned to it. Rather it is attached to a side, the top, or the bottom of the view.

See dockOptions to override default options related to docking the popup.

Default Value:false

Sample - Popup docking

Example

// The popup will automatically be dockEnabled when made visible
view.popup.dockEnabled = true;

dockOptions Property dockOptions Object

Docking the popup allows for a better user experience, particularly when opening popups in apps on mobile devices. When a popup is "dockEnabled" it means the popup no longer points to the selected feature or the location assigned to it. Rather it is placed in one of the corners of the view or to the top or bottom of it. This property allows the developer to set various options for docking the popup.

See the object specification table below to override default docking properties on the popup.

Sample - Popup docking

Example

view.popup.dockOptions = {
  // Disable the dock button so users cannot undock the popup
  buttonEnabled: false,
  // Dock the popup when the size of the view is less than or equal to 600x1000 pixels
  breakpoint: {
    width: 600,
    height: 1000
  }
};

featureCount Property featureCount Numberreadonly

The number of selected features available to the popup.

Default Value:0

features Property features Graphic[]

An array of features associated with the popup. Each graphic in this array must have a valid PopupTemplate set. They may share the same PopupTemplate or have unique PopupTemplates depending on their attributes. The content and title of the popup is set based on the content and title properties of each graphic's respective PopupTemplate.

When more than one graphic exists in this array, the current content of the Popup is set based on the value of the selected feature.

This value is null if no features are associated with the popup.

Example

// When setting the features property, the graphics pushed to this property
// must have a PopupTemplate set.
let g1 = new Graphic();
g1.popupTemplate = new PopupTemplate({
  title: "Results title",
  content: "Results: {ATTRIBUTE_NAME}"
});
// Set the graphics as an array to the popup instance. The content and title of
// the popup will be set depending on the PopupTemplate of the graphics.

fetchFeatures Method fetchFeatures(screenPoint, options){Promise<FetchPopupFeaturesResult>} Since: ArcGIS Maps SDK for JavaScript 4.15 Popup since 4.0, 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 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
