google places autocomplete restrict to particular area - google-maps

Question

My requirement is to get google places autocomplete suggestion only for Bangalore places, but I am not getting places only for Bangalore or within mention latitude longitude.
I want to retireve only below image places in autocomplete textfield.
can someone plz suggest how to achieve the same and where I am going wrong.
Javascript:
<script type="text/javascript">
function initialize1() {
var southWest = new google.maps.LatLng( 12.97232, 77.59480 );
var northEast = new google.maps.LatLng( 12.89201, 77.58905 );
var bangaloreBounds = new google.maps.LatLngBounds( southWest, northEast );
var options = {
bounds: bangaloreBounds,
types: ['(cities)'],
componentRestrictions: {country: 'in'}
};
var input = document.getElementById('searchTextFieldTo');
var autocomplete = new google.maps.places.Autocomplete(input, options);
}
google.maps.event.addDomListener(window, 'load', initialize1);
</script>
TextField:
<input type="text" id="searchTextFieldTo" class="ui-timepicker-hour" style="width:350px;text-align:left;font-style:italic;" placeholder="Enter To location" autocomplete="on" />

Google Provides two ways to achieve this. If you are not satisfied because in countries like India it do not work well, because states and provisions here do not have rectangular or structure boundaries.
1.LatLngBounds (LatLng southwest, LatLng northeast): Where you can give latitude and longitude to form an rectangle.
2. Location (Lat,Lng) & Radius: Where you can give latitude and longitude to form a circle.
But the problem with these approaches they do not provide expected results if you are from countries like India, where states and provisions are not in structured shapes (Rectangular) as in USA.
If you are facing same issue than there is an hack.
With jQuery/Jacascript, you can attach functions which will consistently maintain city name in text input which is bounded with Autocomplete object of Places API.
Here it is:
<script>
$(document).ready(function(){
$("#locality").val(your-city-name) //your-city-name will have city name and some space to seperate it from actual user-input for example: “Bengaluru | ”
});
$("#locality").keydown(function(event) { //locality is text-input box whixh i supplied while creating Autocomplete object
var localeKeyword = “your-city-name”
var localeKeywordLen = localeKeyword.length;
var keyword = $("#locality").val();
var keywordLen = keyword.length;
if(keywordLen == localeKeywordLen) {
var e = event || window.event;
var key = e.keyCode || e.which;
if(key == Number(46) || key == Number(8) || key == Number(37)){
e.preventDefault();
}//Here I am restricting user to delete city name (Restricting use of delete/backspace/left arrow) if length == city-name provided
if(keyword != localeKeyword) {
$("#locality").val(localeKeyword);
}//If input-text does not contain city-name put it there
}
if(!(keyword.includes(localeKeyword))) {
$("#locality").val(localeKeyword);
}//If keyworf not includes city name put it there
});
</script>

Answer 2

As mentioned in my answer here:
It is currently not possible to restrict results to a specific locality. You can use bounds as you have done so above to bias results towards, but not restricted to places contained within the specified bounds.
If you believe restriction by locality would be a useful feature please file a Places API - Feature Request.
EDIT:
As per 2018-07 it's possible to define the types of places to be retrieved, like cities (which are locality or administrative_area3 according to the API). Check out full answer here.

I think you can try this.
var bangaloreBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(12.864162, 77.438610),
new google.maps.LatLng(13.139807, 77.711895));
var autocomplete = new google.maps.places.Autocomplete(this, {
bounds: bangaloreBounds,
strictBounds: true,
});
autocomplete.addListener('place_changed', function () {
});
Note form xomena:
strictBounds option was added in version 3.27 of Maps JavaScript API which is currently (January 2017) the experimental version.

Answer 4

function initialize() {
var bangaloreBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(12.864162, 77.438610),
new google.maps.LatLng(13.139807, 77.711895));
var options = {
bounds: bangaloreBounds,
componentRestrictions: {country: 'in'},
strictBounds: true,
};
var input = document.getElementById('autocomplete');
var autocomplete = new google.maps.places.Autocomplete(input, options);
}
google.maps.event.addDomListener(window, 'load', initialize);

Answer 5

As in the current documentation for Google javascript Places API here, you can define an array of types of places to be retrieved. In the example below, I set it to retrieve only cities (which are, according to the API, locality or administrative_area3). You can set it retrieve regions, addresses, establishments and geocodes as well.
function initMap() {
var input = document.getElementById('my-input');
var options = {
types: ['(cities)']
};
var autocomplete = new google.maps.places.Autocomplete(input, options);
// the rest of the code ...
}
