AutocompleteSearchBox

The AutocompleteSearchBox is used to tie in a Google Maps Places search into a text input field using the Google Maps Places Autocomplete widget.

info

It's recommended to use the AutocompleteSearchBox over PlacesSearchBox because you have more options to configure the search box. See the Places widgets page "Summary of classes" for more information on the differences.

AutocompleteSearchBox extends Evented.

Example usage

const autocompleteSearchBox = G.autocompleteSearchBox('.inputSelector');
autocompleteSearchBox.init().then(() => {
    autocompleteSearchBox.onPlaceChanged((place, bounds) => {
        G.marker({
            map: map,
            position: place.geometry.location,
            tooltip: place.name,
        });
        map.fitBounds(bounds);
    });
});

Creating the AutocompleteSearchBox object

G.autocompleteSearchBox(input?: AutocompleteSearchBoxValue, options? AutocompleteSearchBoxOptions): AutocompleteSearchBox

There are a few ways that you can setup the AutocompleteSearchBox object.

No parameters.

G.autocompleteSearchBox(): AutocompleteSearchBox

const autocompleteSearchBox = G.autocompleteSearchBox();

Pass the options.

G.autocompleteSearchBox(options: AutocompleteSearchBoxOptions): AutocompleteSearchBox

Parameter	Type	Required	Description
options	AutocompleteSearchBoxOptions	Yes	The options.

const autocompleteSearchBox = G.autocompleteSearchBox({
    input: '#inputId'
});

Pass the input selector.

G.autocompleteSearchBox(input: HTMLInputElement | string): AutocompleteSearchBox

Parameter	Type	Required	Description
input	HTMLInputElement \| string	Yes	The input selector.

const autocompleteSearchBox = G.autocompleteSearchBox('#inputId');

Pass the input selector and the options.

G.autocompleteSearchBox(input: HTMLInputElement | string, options: AutocompleteSearchBoxOptions): AutocompleteSearchBox

Parameter	Type	Required	Description
input	HTMLInputElement \| string	Yes	The input selector.
options	AutocompleteSearchBoxOptions	Yes	The options.

const myTextField = document.querySelector('.myInput');
const autocompleteSearchBox = G.autocompleteSearchBox(myTextField, {bounds: myLatLngBoundsObject});

Pass an existing AutocompleteSearchBox object.

G.autocompleteSearchBox(object: AutocompleteSearchBox): AutocompleteSearchBox

In this case the AutocompleteSearchBox object is simply returned.

Parameter	Type	Required	Description
object	AutocompleteSearchBox	Yes	A AutocompleteSearchBox object.

const autocompleteSearchBox = G.autocompleteSearchBox(autocompleteSearchBoxObject);

AutocompleteSearchBox value type

The AutocompleteSearchBoxValue can be one of the following values:

AutocompleteSearchBox object
AutocompleteSearchBoxOptions object
An HTMLInputElement object that is the text input to associate the search box with.
A string CSS selector for the text input to associate the search box with. Any valid selector for document.querySelector can be used.

AutocompleteSearchBox options

Type AutocompleteSearchBoxOptions

Option	Type	Default	Description
bounds	LatLngBoundsValue		A LatLngBounds value type.
countryRestriction	string \| Array \| null	null	The country or countries to restrict the search to. The value should be a single two letter country code or an array of two letter country codes.
fields	string \| Array	['ALL']	The fields to be returned from Google when a Place is found. By default all fields are returned.
input	HTMLInputElement \| string		The input selector.
strictBounds	boolean	false	Whether the Autocomplete widget should only return those places that are inside the bounds of the Autocomplete widget at the time the query is sent.
types	string \| Array		The types of predictions to be returned. For example, you can restrict to certain business types or location types. See setTypes for more information.

tip

You can lower your Google billing by only returning the actual fields that you need for each place.

Events

Below are the events that the AutocompleteSearchBox will emit.

Event	Description
place_changed	Called when the user selects a Place.

place_changed

autocompleteSearchBox.on('place_changed', (event) => {
    // Handle the event
    console.log('Place: ', event.place);
    console.log('Bounds: ', event.bounds);
});

// Or, you can destructure the Event object
autocompleteSearchBox.on('place_changed', ({place, bounds}) => {
    // Handle the event
    console.log('Place: ', place);
    console.log('Bounds: ', bounds);
});

// Or you can call methods to get the data
autocompleteSearchBox.on('place_changed', () => {
    // Handle the event
    console.log('Place: ', autocompleteSearchBox.getPlace());
    console.log('Bounds: ', autocompleteSearchBox.getPlaceBounds());
});

// You can also use the event constant
autocompleteSearchBox.on(G.AutocompleteSearchBoxEvents.PLACE_CHANGED, () => {
    // Handle the event
    console.log('Place: ', autocompleteSearchBox.getPlace());
    console.log('Bounds: ', autocompleteSearchBox.getPlaceBounds());
});

// Or, use the onPlaceChanged() method
autocompleteSearchBox.onPlaceChanged(() => {
    // Handle the event
    console.log('Place: ', autocompleteSearchBox.getPlace());
    console.log('Bounds: ', autocompleteSearchBox.getPlaceBounds());
});

Properties

Properties inherited from Layer.

Property	Type	Description
bounds	LatLngBoundsValue	A LatLngBounds value type.
countryRestriction	string\|Array\|null	The country or countries to restrict the search to. The value should be a single two letter country code or an array of two letter country codes.
fields	string \| Array	The fields to be returned from Google when a Place is found. By default all fields are returned.
input	HTMLInputElement \| string	The input selector.
strictBounds	boolean	Whether the Autocomplete widget should only return those places that are inside the bounds of the Autocomplete widget at the time the query is sent.
types	null \| string \| Array	The types of predictions to be returned. For example, you can restrict to certain business types or location types. See setTypes for more information.

bounds

Get and set the region to use for biasing query predictions. The value returned is the same as getBounds.

Get the bounds. A LatLngBounds object is returned if the bounds exist, otherwise undefined is returned.

const bounds = autocompleteSearchBox.bounds;

Set the bounds. This does the same thing as the setBounds method.

autocompleteSearchBox.bounds = myLatLngBoundsObject;

countryRestriction

Get and set the country restriction(s) for the search.

Get the country restriction(s).

const countries = autocompleteSearchBox.countryRestriction;

Set the country restriction. The value should be a single two letter country code or an array of two letter country codes. You can only set up to five country code strings. See the IBAN ISO codes for a list. (Only use the Alpha-2 codes).

This does the same thing as the setCountryRestriction method.

// Set a single value
autocompleteSearchBox.countryRestriction = 'us';

// Set mulitple country codes
autocompleteSearchBox.countryRestriction = ['es', 'fr'];

fields

Get and set the fields to return for a matched Place.

Get the fields. The value returned is the same as getFields.

const fields = autocompleteSearchBox.fields;

Set the fields to be included for the Place response when a Place is successfully retrieved. If ['ALL'] is passed in, all available fields will be returned and billed for (this is not recommended for production deployments). For a list of fields see the Google PlaceResult documentation. Nested fields can be specified with dot-paths (for example, "geometry.location"). The default is ['ALL'].

This does the same thing as calling the setFields method.

// Set a single field to return
autocompleteSearchBox.fields = 'geometry';
autocompleteSearchBox.fields = ['geometry'];

// Set multiple fields to return
autocompleteSearchBox.fields = ['address_components', 'geometry'];

// Retrieve all fields
autocompleteSearchBox.fields = ['ALL'];

input

Get and set the selector for the text input to associate the search box with.

Get the input. The value returned is the same as getInput.

const input = autocompleteSearchBox.input;

Set the input. This does the same thing as the setInput method.

autocompleteSearchBox.input = document.querySelector('.inputClass');
// Or
autocompleteSearchBox.input = '.inputClass';

strictBounds

Get and set whether the Autocomplete widget should only return those places that are inside the bounds of the Autocomplete widget at the time the query is sent.

Get the value. The value returned is the same as getStrictBounds.

const strictBounds = autocompleteSearchBox.strictBounds;

Set the value. This does the same thing as calling the setStrictBounds method.

Setting strictBounds to false (which is the default) will make the results biased towards, but not restricted to, places contained within the bounds.

Setting strictBounds to true will sell the Autocomplete service to only return those places that are inside the bounds of the Autocomplete widget at the time the query is sent.

autocompleteSearchBox.strictBounds = true;

types

Get and set the types of preditions to return.

Get the value. The value returned is the same as getTypes.

const types = autocompleteSearchBox.types;

Set the value. This does the same thing as calling the setTypes method.

info

See setTypes for more information as there are restrictions on the values that you can set.

// Clear existing types
autocompleteSearchBox.types = null;

// Set a single type
autocompleteSearchBox.types = 'regions';

// Set multiple types
autocompleteSearchBox.types = ['electrician', 'electronics_store', 'hardware_store'];

Methods

Methods inherited from Base.

getBounds

getBounds(): LatLngBounds | undefined

Get the bounds to which query predictions are biased.

const bounds = autocompleteSearchBox.getBounds();

getCountryRestriction

getCountryRestriction(): string|string[]|null

Get the country or countries to restrict the search to.

const countries = autocompleteSearchBox.getCountryRestriction();

getFields

getFields(): string[]

Get the fields to be included for the Place in the details response when the details are successfully retrieved.

const fields = autocompleteSearchBox.getFields();

getInput

getInput(): HTMLInputElement | undefined

Get the HTML input reference that the autocomplete is associated with, if it's set.

const input = autocompleteSearchBox.getInput();

getPlace

getPlace(): google.maps.places.PlaceResult | undefined

Gets the place that has been found. The results from the places_changed event is one place and it's the place that the user clicked on.

const place = autocompleteSearchBox.getPlace();

getPlaceBounds

getPlaceBounds(): LatLngBounds | undefined

Get the map bounds based on the place that has been found. This value is available after the user selected a place.

This is often used to update the map bounds to show the selected place.

myMap.fitBounds(autocompleteSearchBox.getPlaceBounds());

getStrictBounds

getStrictBounds(): boolean

Get whether the Autocomplete widget should only return those places that are inside the bounds of the Autocomplete widget at the time the query is sent.

const strictBounds = autocompleteSearchBox.getStrictBounds();

getTypes

getTypes(): string[] | undefined

Get the types of predictions to be returned.

const types = autocompleteSearchBox.getTypes();

init

init(): Promise<void>

Initialize the places search box object. Call this after you've set the input selector.

important

This must be called in order for the places search box to work.

const autocompleteSearchBox = G.autocompleteSearchBox('.inputSelector');
autocompleteSearchBox.init().then(() => {
    autocompleteSearchBox.on('places_changed', () => {
        const place = autocompleteSearchBox.getPlace();
        G.marker({
            map: map,
            position: place.geometry.location,
            tooltip: place.name,
        });
        map.fitBounds(autocompleteSearchBox.getPlaceBounds());
    });
});

isInitialized

isInitialized(): boolean

Returns whether the places search box object has been initialized.

if (autocompleteSearchBox.isInitialized()) {
    // Do something
}

onPlaceChanged

onPlaceChanged(callback: (place: google.maps.places.PlaceResult, bounds: LatLngBounds) => void): void

This is an alternate option to doing:

autocompleteSearchBox.on('place_changed', (event) => {
    // Handle the event
    console.log('Place: ', event.place)
});

Instead, you can do this:

autocompleteSearchBox.onPlaceChanged((place, bounds) => {
    G.marker({
        map: map,
        position: place.geometry.location,
        tooltip: place.name,
    });
    map.fitBounds(bounds);
});

// Or you can call methods to get the data
autocompleteSearchBox.onPlaceChanged(() => {
    // Handle the event
    console.log('Place: ', autocompleteSearchBox.getPlace());
    console.log('Bounds: ', autocompleteSearchBox.getPlaceBounds());
});
