Trouble with Google Maps Javascript API - javascript

I am new to JavaScript and this website, so please bear with me (and my English) I am doing a draft for my HSC project, for this project I am using Google Maps JavaScript API to show the location of an area. I am unable to find the code to disable the sensor, as the old API thing had in it, instead of 'callback', which would disable the user of the website the ability to move the map around. Would anyone here be able to help me with my issue?
The code I am using is the Google's sample code.
(I have not changed the default location to keep some privacy)

Add this to your map:
draggable: false
For example:
map = new google.maps.Map(document.getElementById('map'), {
center: {lat: -34.397, lng: 150.644},
zoom: 8,
draggable: false
});

Third party latitude and longitude are not matching in google map

I have an external json which I am trying to overlay on a google map. The overall plumbing works fine.
The map gets generated. Data gets iterated, and markers are placed by reading the coordinates. But the when i look at the map the coordinates are way off on the map. The data set can not be wrong, i can give my word on that. Is there some adjustment I need to make to get this thing map to each other. Here is my code

Fusion Tables API and google Maps Advanced Visualization [duplicate]

I prepared a simple page by using the data of a fusion table. ( FusionTablesLayer with Google Maps JavaScript API v3 ) but the map is not displayed. You can see the page here: http://www.siterary.com/0test.html . What's the problem ? The code is as below

<script>
function initialize() {
var istanbul = new google.maps.LatLng(41.01, 28.97);
map = new google.maps.Map(document.getElementById('map_canvas'), {
center: istanbul,
zoom: 11,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
layer = new google.maps.FusionTablesLayer({
query: {
select: 'Location' ,

layer.setMap(map);
}
</script>

The file "/maps/documentation/javascript/examples/default.css" doesn't exist on your site. Your map doesn't have a valid size.
Working version
code snippet:
function initialize() {
var istanbul = new google.maps.LatLng(41.01, 28.97);
map = new google.maps.Map(document.getElementById('map_canvas'), {

Google Maps assign a php pop-up window on clicking a marker

Assume I have put a marker at a specific location on the Map.
I want the program to open a pop-up window called bla.php when the user click on this marker.
This is what I already done to put the marker:
<!DOCTYPE html>

<script type="text/javascript">
function initialize() {
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(48, 2),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
var position = new google.maps.LatLng(48,2);
var marker = new google.maps.Marker({
position: position,
map: map
});
marker.setTitle("pv-unit");
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"/>
</body>
I tried it, the whole map is not loading
First you need an event listener for your marker. Then within that, whatever code you want for opening a popup, e.g.
google.maps.event.addListener(marker, 'click', function() {
window.open('blah.php','name','height=200,width=150');
});

Google Maps API v3 Street View "google is not defined"

I am just getting started with the Maps API and I was trying to copy the following example.
https://code.google.com/apis/maps/documentation/javascript/examples/streetview-simple.html
When I copy the source I get the following error in the script.
google is not defined
Line 11
var fenway = new google.maps.LatLng(42.345573,-71.098326);
This is the html file I am using.

</body>
</html>
The google example loads perfectly but my code does not.
I have seen a few people getting this error but none of the fixes listed seem to work for me. Have I just made a basic error while copying the script?
There is the protocol missing in the path.
//maps.googleapis.com/maps/api/js?sensor=false
should be
http://maps.googleapis.com/maps/api/js?sensor=false
(it's missing in many of the examples)

Button to drop markers on google maps (for a non programmer)

I'm dabbling a bit with google maps and data presentation and was wondering if it is possible to create a button on the map page to drop the markers.
I have no programming experience (I deal with SQL mainly) so any help appreciated - I have the following code taken from varying webistes:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map_canvas { height: 100% }
</style>
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?sensor=false">
</script>
<script type="text/javascript">
// Standard google maps function
function initialize() {
var myLatlng = new google.maps.LatLng(52.469397,-3.208008);
var myOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
TestMarker();
}
// Function for adding a marker to the page.
function addMarker(location) {
marker = new google.maps.Marker({
position: location,
map: map,
animation: google.maps.Animation.DROP
});
}
// Testing the addMarker function
function TestMarker() {
Marker1=new google.maps.LatLng(52.268000,-3.043000); addMarker(Marker1);
Marker23=new google.maps.LatLng(51.524243,-3.193911); addMarker(Marker23);
Marker24=new google.maps.LatLng(51.524243,-3.193911); addMarker(Marker24);
Marker25=new google.maps.LatLng(51.524243,-3.193911); addMarker(Marker25);
Marker26=new google.maps.LatLng(51.524243,-3.193911); addMarker(Marker26);
Marker584=new google.maps.LatLng(51.747777,-3.500599); addMarker(Marker584);
Marker585=new google.maps.LatLng(51.608871,-3.647570); addMarker(Marker585);
}
</script>
</head>
<body onload="initialize()">
<div id="map_canvas" style="border: 1px solid black; width: 500px; height: 400px;">map div</div>
<p style="margin-top: 5px">
<button id="drop">Drop</button>
</p>
</body>
</html>
Now this creates a button, but I can't for the life of me work out how to link this back to my markers. I have found something here that I should be able to adapt but I just don't have the knowhow.
My markers are defined by a sql query, but for now I would like to be able to simply feed in a list and get a drop button to drop them when I click on it.
Any help massively appreciated :)
Remove the call to TestMarker from your initialize function. Then just add an onclick attribute to your button:
<button id="drop" onclick="TestMarker()">Drop</button>
