Google maps not showing up - google-maps-api-3

I have a written a simple code which would display the location on the google map. But for some reasons its not showing up. Any idea whats happening?
<html>
<head>
<title>Google Maps </title>
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
(function() {
window.onload = function(){
var latlng = new google.maps.LatLng(57.8, 14.0);
var options = {
zoom: 6,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map'), options);
}
})();
</script>
</head>
<body>
<div id="map"></div>
</body>
</html>

You need to set dimensions for your map container, try this:
<style type="text/css">
#map {
width: 500px;
height: 500px;
}
</style>

Can't get google.maps.event.trigger(geoXml.docs[0].placemarks[0].marker,'click') to work

I want an infowindow to open automatically when this map is loaded. I'm trying to apply the very fine answer here, the only difference I can see being that I'm triggering a click on a marker rather than on a polygon. I've been staring at and fiddling with the code for a while but just can't get it to trigger that click. What am I missing?
Thanks,
Drew
This pared-down version is using a KML file with one placemark. The relevant code for the event.trigger is down at line 33.

You have a javascript error in your code: Uncaught ReferenceError: geoXml is not defined (because geoXml is undefined). That should be blues in your code.
function initialize() {
var mapOptions = {
zoom: 6,
center: new google.maps.LatLng(47.606209, -122.332069)
};
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var blues = new geoXML3.parser({
map: map,
zoom: false
});
blues.parse('allbluesdance_seattle.kml');
google.maps.event.addListenerOnce(map, 'idle', function () {
alert("Clicking now.");
google.maps.event.trigger(blues.docs[0].placemarks[0].marker, 'click');
});
}
google.maps.event.addDomListener(window, 'load', initialize);

Showing marker on address of the users on google map

I am using Google maps JavaScript API, i get users zip code from database, find lang, lat for it from another table, pass it to JavaScript and show marker on the map.this is showing marker perfectly.
But i want to show marker on exact address of the user instead of just zip code.
But unable to find a way how to do this.
Can anybody please guide me.
Thanks
if you want to place the marker on given lat and lng use this code,
use this code

Blank page when I use FusionTablesLayer with Google Maps JavaScript API v3

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
<!DOCTYPE html>

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

function initialize() {

google-maps-api-3

My application will not recognize my KML file. The application will go to the correct location (lat/long) and zoom level, but will not recognize the KML file location. I have attempted to use two different servers to check the problem, so I believe it is the code that is the problem.

Your kml file does not exist.
http://webgis.uwm.edu/engelki7/KMLFiles/Richfield_Homes2.kml
Gives me: HTTP Error 404 - File or directory not found
If you believe it is there (the path on the server is correct), then it is possible that the server doesn't know how to deal with kml/kmz files. See this portion of the documentation on kml files.

How to change polyline markers in drawing manager?

I test a new drawing library and has led me to question how to get from drawing manager polyline position and set another markers? As in this example: polyline-complex.
My example:
<!DOCTYPE html>

<head>
<title>test</title>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&libraries=drawing"></script>
<style type="text/css">
#map, html, body {
padding: 0;
margin: 0;
height: 100%;
}
</style>
<script type="text/javascript">
function initialize() {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 6,
center: new google.maps.LatLng(52.000, 16.000),
mapTypeId: google.maps.MapTypeId.ROADMAP,
});
drawingManager = new google.maps.drawing.DrawingManager({
drawingMode: google.maps.drawing.OverlayType.POLYLINE,
drawingControl: false,
polylineOptions: {
editable: true
},
map: map
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
