We saw in a similar question that the Places API should return up to 5 results, but right now we are only able to get 1 result. We were following the tutorial to display museums in Sydney. Does anyone know how to display more than one result? The script for the Maps and Places API is below.
let map;
let service;
let infowindow;
function initMap() {
const sydney = new google.maps.LatLng(-33.867, 151.195);
infowindow = new google.maps.InfoWindow();
map = new google.maps.Map(document.getElementById("map"), {
center: sydney,
zoom: 15
});
const request = {
query: "Museum",
fields: ["name", "geometry"]
};
service = new google.maps.places.PlacesService(map);
service.findPlaceFromQuery(request, (results, status) => {
if (status === google.maps.places.PlacesServiceStatus.OK) {
for (let i = 0; i < results.length; i++) {
createMarker(results[i]);
}
map.setCenter(results[0].geometry.location);
}
});
}
function createMarker(place) {
const marker = new google.maps.Marker({
map,
position: place.geometry.location
});
google.maps.event.addListener(marker, "click", () => {
infowindow.setContent(place.name);
infowindow.open(map);
});
}
From the documentation:
Find Place from Query takes a text input and returns a place.
(note the singular "a place")
To get multiple results use nearbySearch (or textSearch)
const sydney = new google.maps.LatLng(-33.867, 151.195);
var request = {
location: sydney ,
radius: '10000',
type: ['museum']
};
service = new google.maps.places.PlacesService(map);
service.nearbySearch(request, (results, status) => {
if (status === google.maps.places.PlacesServiceStatus.OK) {
for (let i = 0; i < results.length; i++) {
createMarker(results[i]);
}
map.setCenter(results[0].geometry.location);
}
});

I am trying to add pins to a Google Map using postcodes stored in a Google Sheet. So far I have been able to access to the Postcodes in the spreadsheet using JSON:
$.getJSON('http://cors.io/?u=https://spreadsheets.google.com/feeds/list/1pksFEATRRWfOU27kylZ1WLBJIC-pMVxKk9YlCcDG0Kk/od6/public/values?alt=json', function(data) {
$.each(data.feed.entry, function(i, v) {
var data = $('<div class="listing">').append('<h4 id="bandb">' + v.gsx$postcode.$t + '</h4>');
$('body').append(data);
});
});
I am also able to add pins to a Google Map using the postcodes.
Example: http://codepen.io/aljohnstone/pen/eJOyrP
I am having trouble combining the two. I would like the postcodes variable in the Codepen to take the postcodes from my Google Sheet.
Working example using the Google Maps Javascript API v3:
$(document).ready(function() {
var geocoder = new google.maps.Geocoder();
var map = new google.maps.Map(document.getElementById("map_canvas"), {
center: {
lat: 54,
lng: -3
},
zoom: 5
});
var i;
var postcodes = [];
$.getJSON('http://cors.io/?u=https://spreadsheets.google.com/feeds/list/1pksFEATRRWfOU27kylZ1WLBJIC-pMVxKk9YlCcDG0Kk/od6/public/values?alt=json', function(data) {
$.each(data.feed.entry, function(i, v) {
postcodes.push(v.gsx$postcode.$t);
});
}).done(function() {
map.setCenter(new google.maps.LatLng(54.00, -3.00));
map.setZoom(5);
var bounds = new google.maps.LatLngBounds();
for (i = 0; i < postcodes.length; i++) {
geocoder.geocode({
'address': "" + postcodes[i]
}, (function(i) {
return function(results, status) {
if (status === google.maps.GeocoderStatus.OK) {
var marker = new google.maps.Marker({
position: results[0].geometry.location,
map: map,
title: postcodes[i]
});
bounds.extend(marker.getPosition());
map.fitBounds(bounds);
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
}
})(i));
}
});
});

So I am trying to make a simple application that will allow the user to search for restaurants and have the results show as markers on the map and as text below. The results object that returns from the textSearch doesn't provide detailed information like: phone number, pictures, etc. So i decided to create an array of place id's pushed from the results object, get the place details for each id, then push that into an array. The problem I get is a message from google saying I'm over my quota and I think it's because I'm requesting the place details for every single search result.
Is there a way I can request the place details only for the marker I click? Or is there a better solution to my problem? Thank you in advance for your help.

I had the same issue some time ago. The geocoding function by google is done in order to avoid the user executing it on a large set of data (and then, avoid you to get a large amount of geocoded address easily).
My solution was to execute the geocoding function only when the user choose a particular place, and then, display this particular data (handled by the click on the pin).
I think it would be very useful to initiate a jsfiddle with a working version of your code.
Basically on your function :
google.maps.event.addListener(marker, 'click', function() {
//Execute geocoding function here on marker object
//Complete your html template content
infowindow.setContent(this.html);
infowindow.open(map,this);
});
A few people have asked this before but with no joy. But, it seems as though recently, google have offered the availability to fetch reviews from your google places via their api.
https://developers.google.com/maps/documentation/javascript/places
I have the url that shows the json of the exact google place I want, however, I cannot see an example on how to fetch the reviews only from this and am completely stuck. Their example shows how to show the map, but not how to fetch the reviews only. Has anyone done this? If so, is there an example of how to do it? Thanks.
Once you have the id of a place you can do
var request = {
placeId: 'place-ID-here' // example: ChIJN1t_tDeuEmsRUsoyG83frY4
};
var service = new google.maps.places.PlacesService(map); // map is your map object
service.getDetails(request, function(place, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
console.log(place.reviews);
}
});
Update with full working example (https://codepen.io/gpetrioli/pen/OmQyEE)
var map, service;
function initMap() {
var central_park = new google.maps.LatLng(40.764243, -73.973049);
map = new google.maps.Map(document.getElementById("map"), {
center: central_park,
zoom: 14
});
var request = {
location: central_park,
radius: "500",
types: ["food"]
};
service = new google.maps.places.PlacesService(map);
service.nearbySearch(request, searchResult);
}
function searchResult(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
// show first result on map and request for details
var place = results[0];
var marker = new google.maps.Marker({
position: place.geometry.location,
map: map,
title: place.name
});
var infowindow = new google.maps.InfoWindow({
content: place.name
});
infowindow.open(map, marker);
service.getDetails({placeId: place.place_id}, function(place, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
let reviewEl = document.querySelector('.reviews');
for (let review of place.reviews){
let li = document.createElement('li');
li.innerHTML = `<div>Author: ${review.author_name}</div>

I am using Google map api v3 to plot markers of location array. My script is
function OnSuccess(response) {
var markers = response.d.split('^^');
var latlng = new google.maps.LatLng(51.474634, -0.195791);
var mapOptions1 = {
zoom: 14,
center: latlng
}
var geocoder = new google.maps.Geocoder();
var infoWindow = new google.maps.InfoWindow();
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions1);
for (i = 0; i < markers.length; i++) {
var data = markers[i];
geocoder.geocode({ 'address': data }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location,
title: data
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
(function (marker, data) {
// Attaching a click event to the current marker
google.maps.event.addListener(marker, "click", function (e) {
infoWindow.setContent(data);
infoWindow.open(map, marker);
});
})(marker, data);
}
where markers variable is bringing proper data, my test data is array of 5 elements
The Game Larder, 24 The Parade, Claygate, Surrey,KT10 0NU
24 The Parade, Claygate, Esher, Surrey KT10 0NU
Card Collection, 14 The Parade, Claygate, ESHER, KT10 0NU
16A The Parade, Claygate, ESHER, KT10 0NU
and same is coming into array markers however it is plotting only two markers. What could be wrong here
Solution
I was entering locations which are very close to each other e.g 1 and 2 point which gives same latlong hence mark as one place. I found latlong here. Thanks for answers btw :)
In page.aspx. insert tag <div id="map-canvas" ></div>
view source page.aspx and insert script into it>
var lis_marker = new Array();
for (i = 0; i < markers.length; i++) {
var data = markers[i];
geocoder.geocode({ 'address': data }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
lis_marker[i] = new google.maps.Marker({
map: map,
position: results[0].geometry.location,
title: data
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
there are difference with your code:
1: var lis_marker = new Array();
2: lis_marker[i] = new google.maps.Marker({...});
Here is the code:
<script type="text/javascript">
var offender_locations = [
["10010", "xxxxx", 3],
["10001", "xxxxx", 2],
["10002", "zzzzz", 1]
];
for (i = 0; i < offender_locations.length; i++) {
var address = offender_locations[i][0];
var icon_img = offender_locations[i][1];
}
</script>
This is the output:
1) 10010 - zzzzz
2) 10001 - zzzzz
3) 10002 - zzzzz
AS you can see var address outputs the correct value, but *var icon_img* does always repeat the same value.
I am a Javascript beginner and I have tried all ways I can think of but I still get the same results.
P.S. I have pasted the full script here :
<script type="text/javascript">
var offender_locations = [
["10010", "offender_icon.png", 3],
["10001", "offender_icon.png", 2],
["10002", "visitor_icon.png", 1]
];
var myOptions = {
zoom: 10,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), myOptions);
var latlng = new google.maps.LatLng(0, 0);
for (i = 0; i < offender_locations.length; i++) {
var infowindow = new google.maps.InfoWindow();
var geocoder_map = new google.maps.Geocoder();
var address = offender_locations[i][0];
var icon_img = offender_locations[i][1];
geocoder_map.geocode({
'address': address
}, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: map.getCenter(),
icon: icon_img
});
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infowindow.setContent(offender_locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
} else {
alert("The requested offender is not mappable !")
};
});
}
</script>
The markers in this script are all # the correct postal code, but they all show the same icon (visitor_icon.png) !
The problem is that you are creating a function in a loop. JavaScript has only function scope, not block scope. I.e. variables you create in a loop exist only once in the whole function, just the values changes per iteration.
At the time icon_img is evaluated (in the callback passed to geocode), the outer for loop already finished and icon_img has the value of the last iteration. It works for address because it is evaluated inside the loop, not later.
You have to 'capture' the current value of icon_img and you can do so by using an immediate function:
for (i = 0; i < offender_locations.length; i++) {
var infowindow = new google.maps.InfoWindow(),
geocoder_map = new google.maps.Geocoder(),
address = offender_locations[i][0],
icon_img = offender_locations[i][1];
(function(addr, img) { // <-- immediate function call
geocoder_map.geocode({'address': addr}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: map.getCenter(),
icon: img
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(addr);
infowindow.open(map, marker);
});
} else {
alert("The requested offender is not mappable !");
}
});
}(address, icon_img)); // <-- immediate function call
}
Maybe you hav to do this for even more variables... not sure.
