Property Details

apiKey Property apiKey String Since: ArcGIS Maps SDK for JavaScript 4.19 LocatorSearchSource since 4.0, apiKey added at 4.19.

An authorization string used to access a resource or service. API keys are generated and managed in the portal. An API key is tied explicitly to an ArcGIS account; it is also used to monitor service usage. Setting a fine-grained API key on a specific class overrides the global API key.

Example

const searchWidget = new Search({
  view: view,
  includeDefaultSources: false,
  sources: [{
    name: "apiKey locator",
    placeholder: "APIs are Key",
    apiKey: "YOUR_API_KEY",
    url: "https://geocode-api.arcgis.com/arcgis/rest/services/World/GeocodeServer"
  }]
});

autoNavigate Inherited Property autoNavigate Boolean Inherited from SearchSource

Indicates whether to automatically navigate to the selected result once selected.

Default Value:true

categories Property categories String[]

A string array which limits the results to one or more categories. For example, Populated Place or airport. Only applicable when using the World Geocode Service.

World Geocode Service documentation

countryCode Property countryCode String

Constricts search results to a specified country code. For example, US for United States or SE for Sweden. Only applies to the World Geocode Service.

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.

defaultZoomScale Property defaultZoomScale Number Since: ArcGIS Maps SDK for JavaScript 4.13 LocatorSearchSource since 4.0, defaultZoomScale added at 4.13.

Sets the scale of the MapView or SceneView for the resulting search result, if the locator service doesn’t return an extent with a scale. An example of this is using the Use current location option in the Search bar.

If you want to override the scale returned by the locator service, use zoomScale instead.

Default Value:null

Example

// create the Search widget
let searchWidget = new Search({
  view: view
});

// wait for the widget to be ready to set the defaultZoomScale
reactiveUtils.when(
  () => searchWidget.viewModel.state === "ready",
  () => {
    let firstSource = searchWidget.allSources.at(0);
    if (firstSource) {
      firstSource.defaultZoomScale = 100000;
    }
  }
);

filter Property filter Object Since: ArcGIS Maps SDK for JavaScript 4.4 LocatorSearchSource since 4.0, filter added at 4.4.

This property replaces the now deprecated searchQueryParams, suggestQueryParams, and searchExtent properties. Setting a value here takes precedence over withinViewEnabled. Please see the object specification table below for details.

Property

geometry Geometry

optional

The filter geometry for suggests or search results. Extent is the only supported geometry when working with locator sources. See Find Address Candidates for additional information.

  xmin: 11376463,
  ymin: -5163501,
  xmax: 18890529,
  ymax: -662888,
  spatialReference: {
    wkid: 3857
  }
});

const searchExtent = {
  geometry: theExtent
};

const sources = [{
  url: "https://geocode-api.arcgis.com/arcgis/rest/services/World/GeocodeServer",
  placeholder: "Darwin",
  maxResults: 3,
  filter: searchExtent
}];

const searchWidget = new Search({
  view: view,
  sources: sources
});

localSearchDisabled Property localSearchDisabled Boolean Since: ArcGIS Maps SDK for JavaScript 4.22 LocatorSearchSource since 4.0, localSearchDisabled added at 4.22.

This property controls prioritization of Search widget result candidates depending on the view scale.

When this property is false (the default value), the location parameter is included in the request when the scale of the MapView or SceneView is less than or equal to 300,000. This prioritizes result candidates based on their distance from a specified point (the center of the view).

When this property is true, the location parameter is never included in the request, no matter the scale of the MapView or SceneView.

Default Value:false

Example

const searchWidget = new Search({
  view: view,
  includeDefaultSources: false,
  sources: [
    {
      name: "ArcGIS World Geocoding Service",
      placeholder: "example: Campton, NH",
      apiKey: "YOUR_API_KEY",
      singleLineFieldName: "SingleLine",
      url: "https://geocode-api.arcgis.com/arcgis/rest/services/World/GeocodeServer",
      localSearchDisabled: true
    }
  ]
});

Defines the type of location, either street or rooftop, of the point returned from the World Geocoding Service.

Possible Values:"rooftop" |"street"

Example

// create the Search widget
let searchWidget = new Search({
  view: view
});

// wait for the widget to be ready to set the locationType
reactiveUtils.when(
  () => searchWidget.viewModel.state === "ready",
  () => {
    let firstSource = searchWidget.allSources.at(0);
    if (firstSource) {
      firstSource.locationType = "rooftop";
    }
  }
);
