Bookmarks | API Reference | ArcGIS Maps SDK for JavaScript 4.31

The Bookmarks widget allows end users to quickly navigate to a particular area of interest. It displays a list of bookmarks, which are typically defined inside the WebMap.

bookmarks

Each bookmark may contain the following properties: name, thumbnail, viewpoint (defines rotation, scale, and target geometry), and timeExtent. If the timeExtent is defined on a bookmark, it will be displayed in the bookmark widget as shown in the following image.

bookmarks-time

When a bookmark with a timeExtent is selected, the timeExtent of the View will be set to the timeExtent of the selected bookmark. To disable time capability in the Bookmarks widget, set capabilities.time in the BookmarksViewModel to false.

container Inherited Property container String |HTMLElement Inherited from Widget

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
view.ui.add(basemapGallery, {
  position: "top-right"
});

// Specify an already-defined HTML div element in the widget's container

const basemapGallery = new BasemapGallery({
  view: view,
  container: basemapGalleryDiv
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

// HTML markup
<body>
  <div id="viewDiv"></div>
  <div id="basemapGalleryDiv"></div>
</body>

// Specify the widget while adding to the view's UI
const basemapGallery = new BasemapGallery({
  view: view
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

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

defaultCreateOptions Property defaultCreateOptions BookmarkOptions Since: ArcGIS Maps SDK for JavaScript 4.18 Bookmarks since 4.8, defaultCreateOptions added at 4.18.

Specifies how new bookmarks will be created if visibleElements.addBookmarkButton is set to true. Can be used to enable or disable taking screenshots or capturing the bookmark's viewpoint based on the current view when a bookmark is created. See BookmarkOptions for the full list of options.

Example

const bookmarks = new Bookmarks({
   view: view,
   visibleElements: {
     addBookmarkButton: true,
     editBookmarkButton: true
   },
   draggable: true,
   // whenever a new bookmark is created, a 100x100 px
   // screenshot of the view will be taken and the rotation, scale, and extent
   // of the view will not be set as the viewpoint of the new bookmark
   defaultCreateOptions: {
     takeScreenshot: true,
     captureViewpoint: false,
     captureTimeExtent: false, // the time extent of the view will not be saved in the bookmark
     screenshotSettings: {
       width: 100,
       height: 100
     }
   }
});

defaultEditOptions Property defaultEditOptions BookmarkOptions Since: ArcGIS Maps SDK for JavaScript 4.18 Bookmarks since 4.8, defaultEditOptions added at 4.18.

Specifies how bookmarks will be edited, if visibleElements.editBookmarkButton is set to true. Can be used to enable or disable taking screenshots or capturing the bookmark's viewpoint based on the current view when a bookmark is edited. See BookmarkOptions for the full list of options.

disabled Property disabled Boolean Since: ArcGIS Maps SDK for JavaScript 4.15 Bookmarks since 4.8, disabled added at 4.15.

When true, the widget is visually withdrawn and cannot be interacted with.

Default Value:false

dragEnabled Property dragEnabled Boolean Since: ArcGIS Maps SDK for JavaScript 4.29 Bookmarks since 4.8, dragEnabled added at 4.29.

Indicates if a Bookmark is able to be dragged in order to update its position in the list.

Default Value:false

editingEnabled Property editingEnabled Boolean Since: ArcGIS Maps SDK for JavaScript 4.13 Bookmarks since 4.8, editingEnabled added at 4.13. Deprecated since 4.29. Use visibleElements.editBookmarkButton, visibleElements.addBookmarkButton, and dragEnabled instead.

Indicates whether the bookmarks are able to be edited. When true, allows bookmarks to be added, edited, reordered, or deleted from within the widget.

When the "edit" icon is clicked, the timeExtent, scale, rotation, and extent of the view will update to match the bookmark's timeExtent (if defined) and viewpoint. A form opens to allow the user to edit the bookmark's title, thumbnail, viewpoint and timeExtent.

Since 4.17: The thumbnail can be "refreshed" (updated to a screenshot of the view's current extent), added from a URL (HTTPS protocol required), or removed. When the "Save" button is clicked, the bookmark's viewpoint is updated to match the current scale, rotation, and extent of the view.

Since 4.22: When adding a bookmark, the timeExtent will be set based on the View's timeExtent, if defined. When editing a bookmark, use the TimeSlider to update the timeExtent of the View. When the "Save" button is clicked, the bookmark's timeExtent is updated to match the timeExtent of the View. The Include time toggle button will remove the timeExtent from a bookmark when toggled off. When toggled on, the timeExtent of a bookmark will be set to the timeExtent of the View.

Any edits made will only be shown locally and will not be saved. See WebMap.save() or WebMap.saveAs() if you want to save the edits to your webmap.

Default Value:false

filterPlaceholder Property filterPlaceholder String Since: ArcGIS Maps SDK for JavaScript 4.29 Bookmarks since 4.8, filterPlaceholder added at 4.29.

Defines the text used as a placeholder when visibleElements.filter is set to true.

filterText Property filterText String Since: ArcGIS Maps SDK for JavaScript 4.29 Bookmarks since 4.8, filterText added at 4.29.

Defines the text used to filter the bookmarks when visibleElements.filter is set to true.

Example

// The following snippet uses the Search widget but can be applied to any
// widgets that support the goToOverride property.
search.goToOverride = function(view, goToParams) {
  goToParams.options = {
    duration: updatedDuration
  };
  return view.goTo(goToParams.target, goToParams.options);
};

headingLevel Property headingLevel Number Since: ArcGIS Maps SDK for JavaScript 4.20 Bookmarks since 4.8, headingLevel added at 4.20.

Indicates the heading level to use for the message "No bookmarks" when no bookmarks are available in this widget. By default, this message is rendered as a level 2 heading (e.g. <h2>No bookmarks</h2>). Depending on the widget's placement in your app, you may need to adjust this heading for proper semantics. This is important for meeting accessibility standards.

Default Value:2

visible Inherited Property visible Boolean Inherited from Widget

Indicates whether the widget is visible.

If false, the widget will no longer be rendered in the web document. This may affect the layout of other elements or widgets in the document. For example, if this widget is the first of three widgets associated to the upper right hand corner of the view UI, then the other widgets will reposition when this widget is made invisible. For more information, refer to the css display value of "none".

Default Value:true

Example

// Hides the widget in the view
widget.visible = false;

visibleElements Property visibleElements VisibleElements Since: ArcGIS Maps SDK for JavaScript 4.13 Bookmarks since 4.8, visibleElements added at 4.13.
