Property Overview

Property Details

activeSourceFeatureLayer|Locatorreadonly

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

activeSourceIndexNumber

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

Default Value: 0

allPlaceholderString

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"

autoSelectBoolean

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.

declaredClassStringreadonly

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

defaultSourceFeatureLayerSource|LocatorSourcereadonly

The default source used for the Search widget.

maxInputLengthNumber

The maximum character length of the search text.

maxResultsNumber

The maximum number of results returned by the widget if not specified by the source.

maxSuggestionsNumber

The maximum number of suggestions returned by the widget if not specified by the source.

If working with the default ArcGIS Online Geocoding service, the default remains at 5.

minSuggestCharactersNumber

The minimum number of characters needed for the search if not specified by the source.

placeholderStringreadonly

The placeholder used by the activeSource.

popupEnabledBoolean

Indicates whether to display the Popup on feature click. The graphic can be clicked to display a Popup. This is not the same as using popupOpenOnSelect which opens the Popup any time a search is performed.

It is possible to have popupOpenOnSelect=false but popupEnabled=true so the Popup can be opened by someone but it is not opened by default.

popupOpenOnSelectBoolean

Indicates whether to show the Popup when a result is selected. Using popupOpenOnSelect opens the Popup any time a search is performed.

It is possible to have popupOpenOnSelect=false but popupEnabled=true so the Popup can be opened by someone but not opened by default.

popupTemplatePopupTemplate

A customized PopupTemplate for the selected feature. Note that specifying a wildcard {*} for the popupTemplate will return all fields in addition to search-specific fields.

resultGraphicGraphicreadonly

The graphic used to highlight the resulting feature or location.

resultGraphicEnabledBoolean

Indicates if the resultGraphic will display at the location of the selected feature.

Default Value: true

resultsObject[]

An array of current results from the search.

searchAllEnabledBoolean

Indicates whether to display the option to search all sources. When true, the "All" option is displayed by default:

When false, no option to search all sources at once is available:

searchTermString

The value of the search box input text string.

selectedResultObject

The result selected from a search.

sourcesCollection

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:

• LocatorSource
• FeatureLayerSource

Any combination of one or more Locator and FeatureLayer 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: i18n.esriLocatorName,
    localSearchOptions: {
      minScale: 300000,
      distance: 50000
    },
    placeholder: i18n.placeholder,
    resultSymbol: new PictureMarkerSymbol({
       url: this.basePath + "/images/search/search-symbol-32.png",
       size: 24,
       width: 24,
       height: 24,
       xoffset: 0,
       yoffset: 0
   })
  }
]

// Example of multiple sources[]
var sources = [
{
  locator: ,
  singleLineFieldName: "SingleLine",
  name: "Custom Geocoding Service",
  localSearchOptions: {
    minScale: 300000,
    distance: 50000
  },
  placeholder: "Search Geocoder",
  maxResults: 3,
  maxSuggestions: 6,
  suggestionsEnabled: false,
  minSuggestCharacters: 0
}, {
  featureLayer: new FeatureLayer({
    url: "https://services.arcgis.com/DO4gTjwJVIJ7O9Ca/arcgis/rest/services/GeoForm_Survey_v11_live/FeatureServer/0",
    outFields: ["*"]
  }),
  searchFields: ["Email", "URL"],
  displayField: "Email",
  exactMatch: false,
  outFields: ["*"],
  name: "Point FS",
  placeholder: "example: esri",
  maxResults: 6,
  maxSuggestions: 6,
  suggestionsEnabled: true,
  minSuggestCharacters: 0
},
{
  featureLayer: new FeatureLayer({
    outFields: ["*"]
  });
  placeholder: "esri",
  name: "A FeatureLayer",
  prefix: "",
  suffix: "",
  maxResults: 1,
  maxSuggestions: 6,
  exactMatch: false,
  searchFields: [], // defaults to FeatureLayer.displayField
  displayField: "", // defaults to FeatureLayer.displayField
  minSuggestCharacters: 0
}
];

// Set source(s) on creation
var searchWidget = new Search({
  viewModel: { // autocasts as new SearchViewModel()
    sources: []
  }
});

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

// Add to source(s)
var searchWidget = new Search();
searchWidget.viewModel.sources.push({ ... });  //new source

suggestionDelayNumber

The millisecond delay after keyup and before making a suggest network request.

suggestionsObject[]readonly
