LocatorSearchSource

Property Overview

Property Details

apiKey String

Since: ArcGIS Maps SDK for JavaScript 4.19

An authorization string used to access a resource or service. API keys are generated and managed in the ArcGIS Developer dashboard. 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 Boolean inherited

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

Default Value:true

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 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 Stringreadonly inherited

Since: ArcGIS Maps SDK for JavaScript 4.7

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

defaultZoomScale Number

Since: ArcGIS Maps SDK for JavaScript 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
searchWidget.watch("viewModel.state", function(state) {
  if (state === "ready") {
    let firstSource = searchWidget.allSources.getItemAt(0);
    if (firstSource) {
      firstSource.defaultZoomScale = 100000;
    }
  }
});

filter Object

Since: ArcGIS Maps SDK for JavaScript 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.

• withinViewEnabled

Example

const theExtent = new Extent({
  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 Boolean

Since: ArcGIS Maps SDK for JavaScript 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
    }
  ]
});

locationType String

Since: ArcGIS Maps SDK for JavaScript 4.12

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
searchWidget.watch("viewModel.state", function(state) {
  if (state === "ready") {
    let firstSource = searchWidget.allSources.getItemAt(0);
    if (firstSource) {
      firstSource.locationType = "rooftop";
    }
  }
});

maxResults Number inherited

Indicates the maximum number of search results to return.

Default Value:6

maxSuggestions Number inherited

Indicates the maximum number of suggestions to return for the widget's input.

Default Value:6

minSuggestCharacters Number inherited

Indicates the minimum number of characters required before querying for a suggestion.

Default Value:1

name String

The name of the source for display.

outFields String[] inherited

Specifies the fields returned with the search results.

placeholder String

Used as a hint for the source input text.

popupEnabled Boolean inherited

Indicates whether to display a Popup when a selected result is clicked.

popupTemplate PopupTemplate inherited

The popup template used to display search results. If no popup is needed, set the source's popupTemplate to null.

This property should be set in instances where there is no existing PopupTemplate configured. For example, feature sources will default to any existing popupTemplate configured on the layer.

prefix String inherited

Specify this to prefix the user's input of the search text.

resultGraphicEnabled Boolean inherited

Indicates whether to show a graphic on the map for the selected source using the resultSymbol.

resultSymbol Symbol inherited

The symbol used to display the result.

Known Limitations

This property only applies when the layer/locator/source is not part of the map.

A template string used to display multiple fields in a defined order when results are displayed.

Example

locatorLayerSource.searchTemplate = "{County}, {State}";

singleLineFieldName String

The field name of the Single Line Address Field in the REST services directory for the locator service. Common values are SingleLine and SingleLineFieldName.

suffix String inherited

Specify this to add a suffix to the user's input for the search value.

suggestionsEnabled Boolean

Indicates whether to display suggestions as the user enters input text in the widget.

Default Value:true

url String

Since: ArcGIS Maps SDK for JavaScript 4.22

URL to the ArcGIS Server REST resource that represents a locator service. This is required.

Example

const sources = [{
  url: "https://geocode-api.arcgis.com/arcgis/rest/services/World/GeocodeServer"
}];

const searchWidget = new Search({
  view: view,
  sources: sources  // autocasts as new LocatorSearchSource()
});

withinViewEnabled Boolean inherited

Indicates whether to constrain the search results to the view's extent.

Default Value:false

zoomScale Number
