Property Overview

Property Details

actionsCollection

Collection of Accessor objects. Each object represents an action that may be executed by clicking the icon or image symbolizing them in the popup. By default, every popup has a zoom-to action styled with a magnifying glass icon . When this icon is clicked, the view zooms in four LODs and centers on the selected feature.

You may override this action by removing it from the actions Collection or by setting the overwriteActions property to true in a PopupTemplate. The order of each action in the popup is the order in which they appear in the actions Collection.

The trigger-action event fires each time an action in the popup is clicked. This event should be used to execute custom code for each action clicked. For example, if you would like to add a zoom-out action to the popup that zooms the view out several LODs, you would define the zoom-out code in a separate function. Then you would call the custom zoom-out function in the trigger-action event handler. See the sample code snippet below for more details on how this works.

Actions are defined with the properties listed in the Action class.

Example:

// Defines an action to zoom out from the selected feature
var zoomOutAction = {
  // 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 font used to style the action button
  className: "esri-icon-zoom-out-magnifying-glass"
};
// Adds the custom action to the popup.
view.popup.viewModel.actions.push(zoomOutAction);

// The function to execute when the zoom-out action is clicked
function zoomOut() {
  // Zoom out two levels (LODs)
  view.goTo({
    center: view.center,
    zoom: view.zoom - 2
  });
}

// This event fires for each click on any action
view.popup.viewModel.on("trigger-action", function(event){
  // If the zoom-out action is clicked, fire the zoomOut() function
  if(event.action.id === "zoom-out"){
    zoomOut();
  }
});

contentString|Node

The content of the popup. When set directly on the Popup, this content may only be static and cannot use fields to set content templates. To set a template for the content based on field or attribute names, see PopupTemplate.content.

See also:

• Sample - Popup Docking

Example:

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

declaredClassStringreadonly

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

featureCountNumberreadonly

The number of selected features available to the popup.

Default Value: 0

featuresGraphic[]

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 poup 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.
var 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.
// Each graphic may share the same PopupTemplate or have a unique PopupTemplate
var graphics = [g1, g2, g3, g4, g5];
view.popup.viewModel.features = graphics;

highlightEnabledBoolean

Since: ArcGIS API for JavaScript 4.4

Highlight the selected popup feature using the highlightOptions set on the SceneView. Currently highlight only works in 3D.

Default Value: true

locationPoint

Geometry used to position the popup. This is automatically set when viewing the popup by selecting a feature. If using the Popup to display content not related to features in the map, such as the results from a task, then you must set this property before making the popup visible to the user.

Examples:

// Sets the location of the popup to the center of the view
view.popup.location = view.center;
// Displays the popup
view.popup.set("visible", true);

// Sets the location of the popup to the location of a click on the view
view.on("click", function(event){
  view.popup.viewModel.location = event.mapPoint;
  // Displays the popup
  view.popup.set("visible", true);
});

pendingPromisesCountNumberreadonly

The number of promises remaining to be resolved.

Default Value: 0

See also:

• Popup.promises

promisesPromise[]

An array of pending Promises that have not yet been fulfilled. If there are no pending Promises, the value is null. When the pending Promises are resolved they are removed from this array and the features they return are pushed into the features array.

selectedFeatureGraphicreadonly

The selected feature accessed by the popup. The content of the Popup is determined based on the PopupTemplate assigned to this feature.

selectedFeatureIndexNumber

Index of the feature that is selected. When features are set, the first index is automatically selected.

stateStringreadonly

The view model's state.

Known Values: ready | disabled

Default Value: disabled

titleString

The title of the popup. This can be set generically on the popup no matter the features that are selected. If the selected feature has a PopupTemplate, then the title set in the corresponding template is used here.

Example:

// This title will display in the popup unless a selected feature's
// PopupTemplate overrides it
view.popup.viewModel.title = "Population by zip codes in Southern California";

viewMapView|SceneView

The view associated with the Popup instance.
