I have tried this code on my own appserv localhost. It works well (both the map and the marker). However, when I uploaded it into remote server, the marker doesn't show up. I have no idea what's wrong since I don't even modify the google example code. Any suggestions would be appreciated.
ps. phpsqlajax_genxml2.php works well on the server since I've test by calling it and it return the correct marker's xml format.
(Here's my code)

You probably forgot to change the API key to reflect the remote server's domain name.

I am aiming to have a map that centre's on a user's current location with markers pulled from a mysql database displayed. I can make my map display a certain lat or lng when specified but I am having trouble taking the user's current location and using this to modify the map's centre.
Any help would be appreciated!
:)

I have done a Google Maps based application in PhoneGap (jQuery mobile). The task is to connect the starting and finishing locations. I am able to link these points by using marker and polyline technique. I can get only a straight line which is connecting both. But, I want to link the two locations via the driving path between these two locations. Like the marked area from the map below. Please help me on this.
I have my code here: http://jsfiddle.net/rajmathan/NALA5/
Update: I also find a code in ActionScript with the same functionality.But,I do not know how to use this in mycode
var directionOptions:DirectionsOptions = new DirectionsOptions({language: 'en',countryCode: 'US,DE',travelMode: DirectionsOptions.TRAVEL_MODE_DRIVING});
<script>
$(document).ready(function(){
navigator.geolocation.getCurrentPosition(onSuccess, onError);
});
function onSuccess(position) {
var vLatitude = 18.9750;
var vLongitude = 72.8258;
var cur_lat = position.coords.latitude;
var cur_lng = position.coords.longitude;
var start = cur_lat+","+cur_lng;
var end = vLatitude+","+vLongitude;
var url = 'https://maps.google.com/?saddr='+start+'&daddr='+end;
location.href = url;
}
function onError(error)
{
alert((error.code)
}
</script>
If you are working with PhoneGap , you should install InAppBrowser and open url like this.. instead of location.href
var ref = window.open(url, 'random_string', 'location=no');
OR
You can also do with...

I am trying to show different points on any route on google map using the API. I want to pass in starting, stopping and finishing locations. Is this possible using the javascript API or would I need to look into other options such as geolocation?
I am using the following code to achieve this:
function initialize() {
var mapOptions = {
zoom: 10,
center: new google.maps.(-64.397, 150.644),
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
}
function loadScript() {
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://maps.googleapis.com/maps/api/js?key=52554&sensor=false&callback=initialize";
document.body.appendChild(script);
}
Here is my code.
`<script type="text/javascript">
var geocoder = null;
var arr = new Array();
var arr1 = new Array();
var arr2 = new Array();
var map = null;
var chr;
var baseIcon = null;
function initialize() {
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById("map_canvas"));
map.setCenter(new GLatLng('<%=Request["Lat"]%>', '<%=Request["Long"]%>'), 13);
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
// Create a base icon for all of our markers that specifies the
// shadow, icon dimensions, etc.
baseIcon = new GIcon();
// baseIcon.shadow = "http://www.google.com/mapfiles/shadow50.png";
baseIcon.iconSize = new GSize(25, 30);
baseIcon.shadowSize = new GSize(37, 34);
baseIcon.iconAnchor = new GPoint(9, 34);
baseIcon.infoWindowAnchor = new GPoint(9, 2);
baseIcon.infoShadowAnchor = new GPoint(18, 25);
// Creates a marker whose info window displays the letter corresponding to the given index.
function createMarker(point, index) {
// Create a lettered icon for this point using our icon class
var letter = String.fromCharCode("A".charCodeAt(0) + index);
var letteredIcon = new GIcon(baseIcon);
letteredIcon.image = "markers/marker" + index + ".png";
// Set up our GMarkerOptions object
markerOptions = { icon: letteredIcon };
var marker = new GMarker(point, markerOptions);
GEvent.addListener(marker, "click", function () {
marker.openInfoWindowHtml("<table><tr><td><img src=markers/marker" + index + ".png length=25 width=25 /></td>" + "<td>" + arr2[index] + "</td></tr></table>");
});
return marker;
}
for (var i = 0; i < arr.length; i++) {
var latlng = new GLatLng(arr[i], arr1[i]);
map.addOverlay(createMarker(latlng, i));
}
}
}

I have generated XML(alarms.xml) in format (example)
<markers>
<marker lat="41.932797" lng="21.483765" alarm="Boston" severity="0" />
<marker lat="41.732797" lng="21.183765" alarm="Toronto" severity="2" />
</markers>
Depending on severity different color for default marker needs to be showed:
0-green
1-violet
2-ocher
etc.
What do I have to change in this my simple html file?
Thanks for help

Before you add the marker, set up a custom icon per severity level:
var severity = parseInt(markers[i].getAttribute("severity"));
var severityIcon = new GIcon(G_DEFAULT_ICON);
var color;
if (severity == 1) color = "red";
else if (severity == 2) color = "blue";
else if (severity == 3) color = "green";
else color = "yellow";
severityIcon.image = "http://www.google.com/intl/en_us/mapfiles/ms/micons/" + color + "-dot.png";
markerOptions = { icon:severityIcon };
Then add it to the map like this:
map.addOverlay(new GMarker(latlng, markerOptions));
This is taken from the excellent Google Maps examples site here: https://google-developers.appspot.com/maps/documentation/javascript/v2/examples/icon-simple
I will really appreciate help for this.
My html v2 file with some temporary key works fine. I am getting locations from some XML, create different colors markers and add some URLs also from XML attributes in Info Window(not too much complicated). Now I need to migrate this to v3. I found some equivalents for functions from v2 but I didn't find for GDownloadUrl( for loading XML) and also GIcon(G_DEFAULT_ICON); Can someone please look at both of my codes and tell me how to change to make this works also in v3. I changed most of the things so if someone can see some error I will be thankful. Thanks in advance.

As you've noted GDownloadUrl() no longer exists in GMap V3. I'd recommend jQuery.get(url)
I posted an example How to parse xml file for marker locations and plot on map.
UPDATE: As #user1191860 points out below there is a utility for GMap V3 xmlparsing. I was not aware of it. AFAIK, no reason not to use it.
You need to add
<script src="http://gmaps-samples-v3.googlecode.com/svn-history/r28/trunk/xmlparsing/util.js"></script>
to your html page.
Interesting that the author also includes a jQuery example
