A significant portion of this code can be eliminated.

HTML excerpt:

<head>
...
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
...
</head>
<body>
...
<input id="searchTextField" type="text" size="50">
...
</body>

Javascript:

function initialize() {
var input = document.getElementById('searchTextField');
new google.maps.places.Autocomplete(input);
}


google.maps.event.addDomListener(window, 'load', initialize);

Just copy and paste the sameple code below.

<!DOCTYPE html>
<html>
<head>
<script src="https://maps.googleapis.com/maps/api/jsvv=3.exp&sensor=false&libraries=places"></script>
</head>
<body>
<label for="locationTextField">Location</label>
<input id="locationTextField" type="text" size="50">


<script>
function init() {
var input = document.getElementById('locationTextField');
var autocomplete = new google.maps.places.Autocomplete(input);
}


google.maps.event.addDomListener(window, 'load', init);
</script>
</body>

Use Google Maps JavaScript API with places library to implement Google Maps Autocomplete search box in the webpage.

HTML

<input id="searchInput" class="controls" type="text" placeholder="Enter a location">

JavaScript

<script>
function initMap() {
var input = document.getElementById('searchInput');
var autocomplete = new google.maps.places.Autocomplete(input);
}
</script>

Complete guide, source code, and live demo can be found from here - Google Maps Autocomplete Search Box with Map and Info Window

To use Google Maps/Places APIs now, you're required to use an API Key. So the API URL will change from

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&signed_in=true&libraries=places"></script>

to

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places"></script>

I am using jQuery here to get the entered text and wrapping all code in $(document).ready(). Make sure you have your API key ready for Google Places API Web service. Replace it in the below script file.

<input type="text" id="location">
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=[YOUR_KEY_HERE]&libraries=places"></script>
<script src="javascripts/scripts.js"></scripts>

Use script file to load the autocomplete class. Your scripts.js file will look something like this.

    // scripts.js custom js file
$(document).ready(function () {
google.maps.event.addDomListener(window, 'load', initialize);
});


function initialize() {
var input = document.getElementById('location');
var autocomplete = new google.maps.places.Autocomplete(input);
}

To get latitude and longitude too, you can use this simple code:

<html>
<head>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places"></script>
<script>
function initialize() {
var input = document.getElementById('searchTextField');
var autocomplete = new google.maps.places.Autocomplete(input);
google.maps.event.addListener(autocomplete, 'place_changed', function () {
var place = autocomplete.getPlace();
document.getElementById('city2').value = place.name;
document.getElementById('cityLat').value = place.geometry.location.lat();
document.getElementById('cityLng').value = place.geometry.location.lng();
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<input id="searchTextField" type="text" size="50" placeholder="Enter a location" autocomplete="on" runat="server" />
<input type="hidden" id="city2" name="city2" />
<input type="hidden" id="cityLat" name="cityLat" />
<input type="hidden" id="cityLng" name="cityLng" />

Follow the below code.

Add this to your TS file.

declare this, top of your class.

declare var google;

declare the view child for Map and the input.

@ViewChild('mapElement', {static: true}) mapNativeElement: ElementRef;
@ViewChild('autoCompleteInput', {static: true}) inputNativeElement: any;

this method is run on ngOnInit() event or ngAfterViewInit() event.

autoComplete() {
const map = new google.maps.Map(this.mapNativeElement.nativeElement, {
center: {lat: -33.8688, lng: 151.2093},
zoom: 7
});


const infowindow = new google.maps.InfoWindow();
const infowindowContent = document.getElementById('infowindow-content');


infowindow.setContent(infowindowContent);


const marker = new google.maps.Marker({
map: map,
anchorPoint: new google.maps.Point(0, -29)
});
const autocomplete = new google.maps.places.Autocomplete(this.inputNativeElement.nativeElement as HTMLInputElement);
autocomplete.addListener('place_changed', () => {
infowindow.close();
marker.setVisible(false);
const place = autocomplete.getPlace();


let cus_location = {
lat: place.geometry.location.lat(),
long: place.geometry.location.lng()
}


console.log('place data :................', cus_location);
localStorage.setItem('LOC_DATA', this.helper.encryptData(cus_location));


if (!place.geometry) {
// User entered the name of a Place that was not suggested and
// pressed the Enter key, or the Place Details request failed.
window.alert('No details available for input: ' + place.name );
return;
}


if (place.geometry.viewport) {
map.fitBounds(place.geometry.viewport);
} else {
map.setCenter(place.geometry.location);
map.setZoom(17);  // Why 17? Because it looks good.
}


marker.setPosition(place.geometry.location);
marker.setVisible(true);
let address = '';
if (place.address_components) {
address = [
(place.address_components[0] && place.address_components[0].short_name || ''),
(place.address_components[1] && place.address_components[1].short_name || ''),
(place.address_components[2] && place.address_components[2].short_name || '')
].join(' ');
}


if(infowindowContent){
infowindowContent.children['place-icon'].src = place.icon;
infowindowContent.children['place-name'].textContent = place.name;
infowindowContent.children['place-address'].textContent = address;
}


infowindow.open(map, marker);
});


}

calling the method on ngAfterViewInit.

ngAfterViewInit(): void {
this.autoComplete();
}

And this is the HTML code. please modify as per your need.

<ion-content fullscreen>
<div class="location-col">




<div class="google-map">
<!-- <img src="../../assets/images/google-map.jpg" alt=""> -->
<div #mapElement id="map"></div>
</div>




<div class="location-info">
<h2>Where is your car located?</h2>
<p>Enter address manually or click location detector icon to use current address.</p>
<div class="form-group">


<div class="location-row">
<input type="text" #autoCompleteInput class="location-input" [(ngModel)]="search_location" placeholder="Search location">
<span class="location-icon" (click)="getCurrentLocation()">
<img src="../../assets/images/location-icon.svg" alt="">
</span>
</div>


<button type="button" class="location-search-btn" (click)="goToVendorSearch()">
<i class="fa fa-angle-right"></i>
</button>


</div>

I am currently using the Google API to retrieve the location that the user enters in the form/ input. I'm also using an angular function that showing the current location and suggests a city name pin code etc... - add google API index.html.
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=xxxxxxxx&libraries=geometry,places"></script>
- add id in input box to get string & charcters.
<input id="autocomplete" type="text"(keydown)="checkAddress($event.target.value)">
- and create function on your component.ts file.
import these file

import * as _ from 'lodash';
declare var google: any;

 checkAddress(value) {
if (!value) {
this.model.location = _.cloneDeep(value);
this.rfpForm.controls['location'].setValue(this.model.location);
}
}

initLocationAutocomplete() {
let autocomplete, place;
const getLocation = () => {
place = autocomplete.getPlace();
if (place && (place.formatted_address || place.name)) {
// if you want set value in your form controls like this
this.model.location = _.cloneDeep(place.formatted_address || place.name);
// YourFormName.controls['location'].setValue(this.model.location);
// YourFormName.controls['location']['_touched'] = true;
}
};
autocomplete = new google.maps.places.Autocomplete((document.getElementById('autocomplete')), { types: ['geocode'] });
autocomplete.addListener('place_changed', getLocation);
}

So I've been playing around with this and it seems you need both places and js maps api activated. Then use the following:

HTML:

<input id="searchTextField" type="text" size="50">
<input id="address" name="address" value='' type="hidden" placeholder="">

JS:

<script>
function initMap() {
var input = document.getElementById('searchTextField');
var autocomplete = new google.maps.places.Autocomplete(input);
autocomplete.addListener('place_changed', function() {
var place = autocomplete.getPlace();
document.getElementById("address").value = JSON.stringify(place.address_components);
});
}
</script>


<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places&callback=initMap" async defer></script>
