Search | API Reference | ArcGIS Maps SDK for JavaScript 4.33

ESM: import Search from "@arcgis/core/widgets/Search.js";

CDN: const Search = await $arcgis.import("@arcgis/core/widgets/Search.js");

Class: @arcgis/core/widgets/Search

Since: ArcGIS Maps SDK for JavaScript 4.0

The Search widget provides a way to perform search operations on locator service(s), map/feature service feature layer(s), SceneLayers with an associated feature layer, BuildingComponentSublayer with an associated feature layer, GeoJSONLayer, CSVLayer, OGCFeatureLayer, and/or table(s). If using a locator with a geocoding service, the findAddressCandidates operation is used, whereas queries are used on feature layers.

By default, the Search widget uses the ArcGIS World Geocoding Service via this URL: https://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer. If a global apiKey is present, the Search widget uses this URL: https://geocode-api.arcgis.com/arcgis/rest/services/World/GeocodeServer. If an apiKey is present on the LocatorSearchSource, then the Search widget uses the URL defined by the LocatorSearchSource.url property.

The Search widget sets the view on the Search result. The level of detail (LOD) at the center of the view depends on the data source, with higher quality data sources returning extents closer to the feature obtained from the search. To manually define the scale of the view at the Search result, use the zoomScale property of the LocatorSearchSource or LayerSearchSource.

Search widget results are typically sorted according to their relevance to the search and their relative importance. However, when the scale of the MapView or SceneView is less than or equal to 300,000, the operations support prioritization of candidates based on their distance from a specified point (the center of the view) by passing in the location parameter. Features closest to the input location show up higher in the list of results. This behavior can be changed by using the localSearchDisabled property.

You can use the view's DefaultUI to add widgets to the view's user interface via the ui property on the view. See the example below.

Example

const searchWidget = new Search({
  view: view
});
// Adds the search widget below other elements in
// the top left corner of the view
view.ui.add(searchWidget, {
  position: "top-left",
  index: 2
});

Property Details

activeMenu Property activeMenu String

The current active menu of the Search widget.

Possible Values:"none" |"suggestion" |"source" |"warning"

activeSourceIndex Property activeSourceIndex Number: The selected source's index. This value is -1 when all sources are selected.

String value used as a hint for input text when searching on multiple sources. See the image below to view the location and style of this text in the context of the widget.

Default Value:"Find address or place"

Since: ArcGIS Maps SDK for JavaScript 4.8 Search since 4.0, allSources added at 4.8.: The combined collection of defaultSources and sources. The defaultSources displays first in the Search UI.

autoSelect Property autoSelect Boolean: Indicates whether to automatically select and zoom to the first geocoded result. If false, the findAddressCandidates operation will still geocode the input string, but the top result will not be selected. To work with the geocoded results, you can set up a search-complete event handler and get the results through the event object.

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"
});

// The following snippet uses Search 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);
};

Example

// includeDefaultSources passed as a boolean value
const searchWidget = new Search({
  view: view,
  sources: [customSearchSource],
  includeDefaultSources: false
});

// includeDefaultSources passed as a function
const searchWidget = new Search({
  view: view,
  sources: [customSearchSource],

For more information, refer to the css display value of "none".

Example

// Hides the widget in the view

Parameter

optional

This searchTerm can be a string, geometry, suggest candidate object, or an array of [longitude,latitude] coordinate pairs. If a geometry is supplied, then it will reverse geocode (locator) or findAddressCandidates with geometry instead of text.
