Add Google API javascript file in the HTML header section.

Google Maps JavaScript API and Locations Library, are used to search for locations and display location predictions in the autocomplete box. This javascript file will load the Address Autocomplete Google API class.

<script src="http://maps.googleapis.com/maps/api/js?key=
YOUR GOOGLE API KEY
&libraries=places&callback=initMap" async defer 
type="text/javascript"></script>

Javascript

Define the search box ID attribute of the component and specify this ID as a selector (searchInput) in JavaScript code.

function initMap() {
    var input = document.getElementById("searchMap");

    var autocomplete = new google.maps.places.Autocomplete(input);

    autocomplete.addListener("place_changed", function () {
        var place = autocomplete.getPlace();
        document.getElementById("locationPlace").innerHTML = place.formatted_address;
        document.getElementById("latitude").innerHTML = place.geometry.location.lat();
        document.getElementById("longitude").innerHTML = place.geometry.location.lng();
    });
}
