Property Overview

Property Details

activeSourceFeatureLayerSearchSource|LocatorSearchSourcereadonly

The source object currently selected. Can be either a feature layer or a locator task.

activeSourceIndexNumber

sourcesCollection<(FeatureLayerSearchSource|LocatorSearchSource)>

The Search widget may be used to search features in a FeatureLayer or geocode locations with a Locator. The sources property defines the sources from which to search for the view specified by the Search widget instance. There are two types of sources:

• FeatureLayerSearchSource
• LocatorSearchSource

Any combination of these sources may be used together in the same instance of the Search widget.

Examples:

// Default sources[] when sources is not specified
[
  {
    locator: new Locator("//geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer"),
    singleLineFieldName: "SingleLine",
    outFields: ["Addr_type"],
    name: "ArcGIS World Geocoding Service",
    localSearchOptions: {
      minScale: 300000,
      distance: 50000
    },
    placeholder: i18n.placeholder,
    resultSymbol: {
       type: "picture-marker",  // autocasts as new PictureMarkerSymbol()
       url: this.basePath + "/images/search/search-symbol-32.png",
       size: 24,
       width: 24,
       height: 24,
       xoffset: 0,
       yoffset: 0
   }
  }

},
{
  featureLayer: new FeatureLayer({
    outFields: ["*"]
  });
  placeholder: "esri",

var searchWidget = new Search({
  viewModel: { // autocasts as new SearchViewModel()
    sources: []
  }
});

// Set source(s)
var searchWidget = new Search();
var sources = [{ ... }, { ... }, { ... }]; //array of sources
