Center marker in Google Maps - javascript

I am trying to center a Google map in an iframe. The code below is the content of the iframe.
The marker is not in the center of the frame.
What is missing?
<!DOCTYPE html>
<html>
<head>
<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?key=MYAPIKEY&sensor=false"></script>
<script type="text/javascript">
function initialize() {
var myLatlng = new google.maps.LatLng('<?php echo $this->uri->segment(5); ?>', '<?php echo $this->uri->segment(4); ?>');
var myOptions = {
zoom: 8,
mapTypeControl: false,
scaleControl: false,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Hello World!"
});
}
initialize();
</script>
</head>
<body onload="initialize()">
<div id="map_canvas" style="width:100%; height:100%"></div>
</body>
</html>
UPDATE
I think I have solved it buy setting a fixed size for the map_canvas instead of using 100%.
I works much better now.

Your code works for me -> http://jsfiddle.net/yRHJv and in jsfiddle the map is inside of iframe.
I have replaced your PHP code with some dummy data.

you should set a size to your div#map like so:
#map1 {
height: 100%;
width: 100%;
}
Adjust according your needs of course.
The crux of your problem goes to integrating google map with bootstrap.In details, you should set the css height style of map tag's parent div(.container-fluid) to 100%;
In order to make the following demo run normally,you should provide your google map api key and your picture file for the marker.

marker.setMap(map);

PS: this is the first time I used google maps,so maybe some code is weird.I have tried as the following procedure.
1.see google maps getting started page.
2.add customized marker.
3.integrate with bootstrap.
Hope it can help you.

zoom_changed listener doesn't work for me

I'm trying to use a zoom listener event in a google maps so that I can resize some axis I have in it. As a beginning, I'm trying to use an alert so that I can see whether if the listener detects a change in the zoom level or not, but I'm not able to get any alert at all. My code is the following:
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>

function initialize() {
var centerlatlng = new google.maps.LatLng(49.801674, 11.188139);
var myOptions = {
zoom: 18,
center: centerlatlng,
scaleControl:true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
* plotting stuff *
google.maps.event.addDomListener(window, 'load',initialize);
google.maps.event.addDomListener(maps,'zoom_changed', function()
{
alert("changed");
});
</script>
</head>
<body>
<div style="text-align:center;">
<button onclick="draw_axis()">Enable/Disable Axis</button> <br><br> <div id="log"></div>
</div>
<div id="map_canvas" style="width: 100%; height: 90%;"></div>
</body>
</html>
Does anyone see the problem?
The map variable isn't defined when you create the zoom_changed listener, it is created later, when the initialize function runs (also the variable is map, not maps).
code snippet:
var map;
function initialize() {
var centerlatlng = new google.maps.LatLng(49.801674, 11.188139);
var myOptions = {
zoom: 18,
center: centerlatlng,
scaleControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addDomListener(map, 'zoom_changed', function() {
alert("changed");
});
}
google.maps.event.addDomListener(window, 'load', initialize);
html,
body,
#map_canvas {
height: 100%;
width: 100%;
margin: 0px;
padding: 0px
}
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCkUOdZ5y7hMm0yrcCQoCvLwzdM6M8s5qk"></script>
<div style="text-align:center;">
<div id="log"></div>
</div>
<div id="map_canvas" style="width: 100%; height: 90%;"></div>
You need to set zoom_changed event on the instance of google.maps.Map inside your initialize() function.
map.addListener('zoom_changed', function() {
alert("changed");
});

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

var istanbul = new google.maps.LatLng(41.01, 28.97);
map = new google.maps.Map(document.getElementById('map_canvas'), {

mapTypeId: google.maps.MapTypeId.ROADMAP

layer = new google.maps.FusionTablesLayer({
query: {
select: 'Location' ,

The file "/maps/documentation/javascript/examples/default.css" doesn't exist on your site. Your map doesn't have a valid size.

function initialize() {
var istanbul = new google.maps.LatLng(41.01, 28.97);

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>
<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="https://maps.googleapis.com/maps/api/js?key=AIzaSyDxVucBtLP4XefoM4syoigBgXntwkVGxv8&sensor=false">
</script>
<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');
});
