Google Maps API marker move on scroll and layout style - javascript

I'm new in the Google Maps API, I am trying to embed a marker with the address on google maps but I have errors.
https://developers.google.com/maps/documentation/javascript/adding-a-google-map#map
I'm using this documentation and I have copied this code but it doesn't work properly because when you scroll the marker it's not fixed in the map but its move and doesn't stay in the correct place.
Also, the buttons in the left corner MAP and SATELLITE doesn't appear properly, they appear with a background line in the whole map and don't together smaller.
Finally, the + and - button doesn't appear.
Someone could tell me why I have all this problem?
Here is my code:
<script>
function initMap() {
var blitz8 = {lat: 45.806510, lng: 10.109520};
var map = new google.maps.Map(document.getElementById("map"), {
zoom: 18,
center: blitz8
});
var marker = new google.maps.Marker({
position: blitz8,
map: map
});
};
</script>
And here the Live Page:

Hi I resolve that problem by disabled some css option in your base.scss please check and fix that, check my picture uploaded below

google maps refresh without displaying gray

I am using the Google Maps API v3 in javascript, and I am constantly reloading the map with an app.get, and adding layers and bookmarks using mongodb. To erase everything I reload the map, and while it's loading a gray background displays in the div that contains the map.
What technique do you recommend so that the gray transition is not displayed, and the map is displayed all at once?
I'm reloading the map with the following code, within the function that does the reload; if I put this code outside of the function, the new elements that arrive will appear on top. This is why I do it this way.
var geocoder,map
geocoder = new google.maps.Geocoder();
var options = {
zoom: 5,
minZoom: 5,
center: new google.maps.LatLng(5.1573603, -74.982409),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'), options);
You can first set the visibility of the div which contains map to hidden; then listen to the first tilesloaded event, and set the visibility back to visible. Doing this the Maps should only pop up after all it tiles is loaded (so no gray screen)
Here is a quick demo which do just that:

Google Maps API : Display location with Marker and Description

I am working on my own website, and everything is starting to come together except for the buttons. Currently, when the location button is clicked, a JS alert message appears. This is unacceptable! What I would like to do instead is have a little box appear with the Google Maps map of some location with a pin. This could be a jpg or png for all it matters. The important thing is to have it appear and have an X to close it in the top right. To see what I mean, go to my site: http://andreihetman.com and click on the location pin.
Check out the Google Maps API Documentation relative to markers
Anyway here is a sample:
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
zoom: 4,
center: myLatlng
}
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
}
NOTE: By reading the API you will find out even how to add a detail box.

Set Google maps coordinates as center screen

I wrote a script which allows an admin to click on a map (google maps api v3) setting up as many locations as he wants, naming them. That is, clicking on the map shows an information window with a form for naming that location. These locations are saved in a database (LatLng coordinates) and show as markers on the map.
Then, users (admin or not) may choose any of these locations from a select box (by name). Once this is selected, there's an option for showing a map with a marker on the selected location. The marker shows correctly, but I would like the map to be centered in that location. That is, the marker in the center of the screen but, instead, it shows in the extreme upper left corner. Actually, initially, the marker isn't even visible. You have to drag the map up and left a little for it to show.
This is rather strange, as I use the same coordinates for both the marker and the center screen. Here's my code (or the relevant part, at least):
var latlng = new google.maps.LatLng(parseFloat(location.lat), parseFloat(location.ltn));
var latlng2 = new google.maps.LatLng(parseFloat(location.lat) + 0.025, parseFloat(location.ltn) - 0.05);
var map = new google.maps.Map($('.modal-body', modal)[0], {
'center': latlng,
'zoom': 13,
'mapTypeId': google.maps.MapTypeId.ROADMAP,
});
var marker = new google.maps.Marker({
'position': latlng,
'map': map,
'title': location.name,
});
marker.setMap(map);
Notice how in this sample I don't use the latlng2 value. This is what I tried, but it seems to only work for a given resolution. How can I center the map in those coordinates?
Best regards
Edit:
$(map).focus();
modal.on('shown', function() {
$(window).resize(function() {
google.maps.event.trigger(map, 'resize');
});
google.maps.event.trigger(map, 'resize');
});
I'm not sure if this will work... If that window resize is cause than it might help. I don't know how it will interact with other code.
Add event listener for resize event:
...
marker.setMap(map);
google.maps.event.addListener(map, 'resize', function() {
map.setCenter(latlng);
});

Google maps not display entire map on the div container

I have a div with a google map inside but the map is not showing entirely.. just shows a part of the map and the other it's all grey and if i move the map with the cursor, the maps visual part moves fine but the size changes but not taking the entire div size.
This is the div and a snapshot:
<div style="height: 275px; width: 715px;" id="map_display"></div>
You need to trigger a resize event in Google maps like
google.maps.event.trigger(myMap, 'resize');
After initializing the Google maps
The answer provided Here may be of use to you, the problem is likely that the map has been loaded prior to the sizing of the div (is it perhaps dynamically sized?).
Loading the map after the rest of the page elements should help.
Working Fiddle
function InitializeMap() {
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_display"), myOptions);
}
$(document).ready(function () {
InitializeMap();
});

Google Maps API - Strange Map "Offset" Behaviour

I'm adding a map next to a form on my web page. The idea is that people can sign up, and when they type in their address and click search, it place-marks their house, they must do this before they submit the form (geolocation has a large role on my site).
Unfortunately, I have added the map, but within the map window the map itself appears to be offset. See the image below to illustrate what I mean:
I can only drag the map from within the "mapped" part of the box. If I select the grey area to drag the map around, it fails.
Any ideas what could cause this?
EDIT:
Here is my map-initialising Javascript, called on page load.
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(52.428385,-3.560257);
var myOptions = {
zoom: 7,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("adminMap"), myOptions);
Here is my map CSS
#adminMap{
float:left;
width:270px;
height:370px;
margin-left:20px;
}
Here is my map HTML
<div id="adminMap">
</div>
I've seen things similar to this. Without access to any code, my best bet is that the map is initialized at a time when the container div is hidden. I've seen that cause such symptoms. Try to set up your map as you're showing it, rather than before.
To render the map fully again on changing div visibility you can use this code.
google.maps.event.trigger(map, 'resize');
This will rerender your map inside the div and will display it fully.
