I'm developing a website that requires to get and show user's location.
However, I get this error message every time I run the project:

What's I'm doing wrong???
can anyone help please??
I solved my problem !
I just added this line of code to add my API Key:

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,

});
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);

Kinda of new to Google mashups. I have an KML on our Webserver (http://www.madisonareampo.org/maps/BRT_National.kmz) to draw on Google Maps.
I have a Google Maps mashup where I want an infowindow to display the contents of the KML description field through a click event. The KML file was exported from a geodatabase using ArcGIS.
Nothing is being returned when I click on a marker in the KML file.

InfoWindows needs a position attribute and you have to call open(map) to bind it to the map. Here's a working version of your code :
google.maps.event.addListener(layer, 'click', function(kmlEvent) {
showInContentWindow(kmlEvent.latLng, kmlEvent.featureData.description);
});
function showInContentWindow(position, text) {
var content = "<div style='margin-left:-20px;border:2px dotted #897823;'>" + text + "</div>";
var infowindow = new google.maps.InfoWindow({
content: content,
position: position
})
infowindow.open(map);
}
The default infoWindow size is way too big for me. I want it to be much smaller can I can't figure out how to do it. I've tried setting a maxWidth parameter on my infoWindow constructor like this
var infowindow = new google.maps.InfoWindow({'maxWidth':'10px'});
and setting the CSS width like this
<style type="text/css">
#infoWindow {
width: 10px;
}
</style>
but that only seems to change the size of the text wrapping, not the actual box. How do I change the size of the infoWindow box?
Here is my code.

The native infoWindow has a minimum size. If it is to big for you, you need to look at using an alternative solution like infoBubble or InfoBox
your CSS section doesn't do anything because var infoWindow is not the same as <div id="infoWindow">
The documentation says:
maxWidth: Maximum width of the infowindow, regardless of content's width. This value is only considered if it is set before a call to
open. To change the maximum width when changing content, call close,
setOptions, and then open.
Also what Larry, (geocodezip), said. (he types faster than me) ;-)
This is a drop down Div - which works with everything except GoogleMap.
I get half the map showing or maybe a 1/4 of it... When I get rid of the div's all works fine... Or is there a workaround without div's? Ideas... I tried declaring table, p etc... No luck...
Javascript Drop Down Code and Div calls
<script type="text/javascript">
function showElement(layer){
var myLayer = document.getElementById(layer);
if(myLayer.style.display=="none"){
myLayer.style.display="block";
myLayer.backgroundPosition="top";
} else {
myLayer.style.display="none";
}
}
</script>
<div class=catlist>
<table border=0 cellpadding=4>
<tr>
<td valign=middle><img src="images/plus.png" onclick="javascript:showElement('ed')"></td>
<td valign=middle><a href="#" onclick="javascript:showElement('ed')"><b>Edit GPS
Map</b></a></td>
</tr></table>
</div>
<div class="qlist" id="ed" style="display:none;">
<div id="map" style="width: 500px; height: 250px;"></div>
</div>
Adding the Google Javascript...
This is the actual Google Maps Javascript...
Cold Fusion Plots the # markers...
This works fine outside of divs...
Code suggested above works to display the correct map interface...
But the centering of the plot is not working...
And marker shows at top left corner with above code provided...
<div id="map" style="width: 500px; height: 250px;"></div>
<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript">
</script>
<script type="text/javascript">
var locations = [
["#bsname#", #gpslat#, #gpslong#, #busid#],
];
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 15,
center: new google.maps.LatLng(#gpslat#, #gpslong#),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}
</script>
The changes I made were:
triggering a resize when the div is expanded
centering the map after the resize
making map and locations variables global.

Making the map resize after you show the div should work:
From the docs: "Developers should trigger this event on the map when the div changes size:" google.maps.event.trigger(map, 'resize') .
EDIT - I'll be more specific, please try again
function showElement(layer){
var myLayer = document.getElementById(layer);
if(myLayer.style.display=="none"){
myLayer.style.display="block";
myLayer.backgroundPosition="top";
// *** add the trigger here ***
google.maps.event.trigger(map, 'resize')
} else {
myLayer.style.display="none";
}
}

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?

var map = new google.maps.Map(document.getElementById('map'), options);

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