Info window with place details is not showing (Google Places API) - javascript

I created a city specific film production company locator. I'm using the nearbySearch service with pagination of all places. Until that point everything is working fine.
Now I'm trying to add the getDetails service to display company info in an info window. Unfortanly I didn't figure out how to display an info window for each marker with the data from the getDetails service. I would be very thankful if someone can help me out to solve my problem! I put the code below!
var map;
var labels = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890';
var labelIndex = 0;
function initMap() {
// Create the map.
var duesseldorf = {lat: 51.2277, lng: 6.7735};
map = new google.maps.Map(document.getElementById('map'), {
center: duesseldorf,
zoom: 12
});
// Create the places service.
var service = new google.maps.places.PlacesService(map);
var getNextPage = null;
var moreButton = document.getElementById('more');
moreButton.onclick = function() {
moreButton.disabled = true;
if (getNextPage) getNextPage();
};
// Perform a nearby search.
service.nearbySearch(
{location: duesseldorf, radius: 14000, keyword: ['filmproduktion']},
function(results, status, pagination) {
if (status !== 'OK') return;
createMarkers(results);
moreButton.disabled = !pagination.hasNextPage;
getNextPage = pagination.hasNextPage && function() {
pagination.nextPage();
};
});
}
//display place details in info window

I get a javascript error with the posted code: Uncaught ReferenceError: google is not defined on this line: var infowindow = new google.maps.InfoWindow();, because that is outside of initMap so executes before the API is loaded. Make it global (var infowindow;), then initialize it inside initMap.
var infowindow;
function initMap() {
infowindow = new google.maps.InfoWindow();
Then to open the details in the infowindow, call the getDetails request when the marker is clicked, opening the infowindow when the response comes back, keeping track of the reference to the marker from the click event (the var that=this; line, that gives you function closure on that so it is available when the response comes back to the getDetails request):

combining google street view with places search

For a project I'm currently working on, I'm looking to incorporate both elements of Google places to search with google street view, essentially forcing the location (after searching) to view as street/pano.
Google has a pretty solid 'basic' version but I can't seem to force it to use street view. Any insight would be awesome.
https://developers.google.com/maps/documentation/javascript/examples/places-searchbox
https://www.instantstreetview.com/ - Seems to do a pretty good job of it, but I can't seem to find any documentation regarding both.
Combine the code from the SearchBox example, with the StreetView example, should give you a first cut.
Probably more what you are looking for would be to combine the answer to this related question: Facing the targeted building with Google StreetView, with the SearchBox example
proof of concept fiddle
code snippet:
// This example adds a search box to a map, using the Google Place Autocomplete
// feature. People can enter geographical searches. The search box will return a
// pick list containing a mix of places and predicted search terms.
// This example requires the Places library. Include the libraries=places
// parameter when you first load the API. For example:
// <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">

What's wrong with my search that doesn't display their marker in google map?

I created a places search google map that likes to search for places like types of schools, I made a marker for both private and public, the search box works, but when I click enter, It does not show the public/private schools, Is this because of my code? on icon? or marker?
The only problem is when I click enter, It does not display its markers

Getting user's location for google Maps

So I'm trying to have google maps with direction service It works fine until I try to get the user's location to use as a start point. The idea is to give a user directions from their current location to one of the three. I have been following along with some guides on on Google's API.
When I try to get the user's location I try using:
if (navigator.geolocation) {
var position = navigator.geolocation.getCurrentPosition();
googleCoords = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
}
else {
alert("No geolocation!");
}
But for some reason this breaks the map? Trying to get the user's coordinates in a variable to use in the Directions services and as an origin for the map. Thanks

You must do into a function getCurrentPosition.
navigator.geolocation.getCurrentPosition(function(position) {
var pos = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
you should get the position from callback function like this.
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position){
var googleCoords = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
});
} else {
alert("Geolocation is not supported by this browser.");
}

Reverse Geocoding example doesn't display the street name of a location in some regions

This reverse geocoding code does not return the street name of a location in some areas (Example: {36.82687, 10.09948}), actually, I get only the name of the town and the country despite the fact that the name of the street is available on the map. I was wondering if there was a trick to get the streets' names in those regions?
Thanks for your help.
The example you reference returns the formatted_address of the 2nd entry ("[1]") in the results array. The most detailed entry is usually the 1st entry ("[0]"). If I change the code to use that, I get the street name.

If you really only want the street name, you should not depend on the entry in the results array, you should iterate through the results of the first (most exact) entry, looking for the address_component with type route
