SCRIPT TO LOAD MAP AND AUTOCOMPLETE WITH POLYGON REGION
<script>
var map;
var google;
var latlong;


$(document).ready(function () {
    initialize();
});

function initialize() {

var myLatlng1 = new google.maps.LatLng(12.9716, 77.5946);

var mapOptions = {
 zoom: 8,
 center: myLatlng1,
 mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('mapCanvas'),mapOptions);

var zone = [[14.022132, 75.571558], 
            [14.681398, 77.602789], 
            [13.627854, 79.420593], 
            [12.116034, 78.162132], 
            [11.986247, 75.376120]
           ];

var box = [];
$.each(zone, function(index, item){
    var kpoint = new google.maps.LatLng(item[0], item[1]);
    box.push(kpoint);
});


polygon_area = new google.maps.Polygon({
    path: box,
    map: map,
    strokeColor: '#2cae72',
    strokeOpacity: 0.8,
    strokeWeight: 1,
    fillColor: '#2cae72',
    fillOpacity: 0.2
});
}

$(function () {
    $("#PickupAddress")
        .geocomplete()
        .bind("geocode:result", function (event, result) {
        $("#spanPick").text($("#PickupAddress").val());
        
        var latitude  = result.geometry.location.lat();
        var longitude = result.geometry.location.lng();
        
        $('#pickupLatitude').val(latitude);
        $('#pickupLongitude').val(longitude);
                
        var curPositionB = new google.maps.LatLng(latitude, longitude);
        var result = google.maps.geometry.poly.containsLocation(curPositionB, polygon_area);
        if(result == true){
        routeDirection("PickupAddress", curPositionB);
        }else{
        $('.showerror').show();
        $(".showerror").hide( 5000 );
        $('#PickupAddress').val('');
        $('#PickupAddress').focus();
        }   
        
      });





function routeDirection(id, latLong) {
    geocoder = new google.maps.Geocoder();
    var mapOptions = {
        zoom: 12,
        center: latLong,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    map = new google.maps.Map(document.getElementById('mapCanvas'), mapOptions);
    var start = $("#PickupAddress").val();
    if (start != null) {
        geocoder.geocode({ "address": start }, function (results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                map = new google.maps.Map(document.getElementById('mapCanvas'), mapOptions);
                marker = new google.maps.Marker({
                    position: latLong,
                    map: map,
                });
            }
        });
    }
  };





});
</script>

the variable zone in script, you can add more number of region as you need. you can change it. routeDirection function is to show the marker after you selected the place. and for this you need to add google api library places for autocomplete and geometry for containsLocation.
