I am a newbie in Google Maps API.
I have a XML file that contains the following:
<?xml version="1.0"?>
-<Customers>-
<Marker category="Production">
<title lang="en">Invensys</title>
<site_location>Neponset Avenue 22, Foxborough, Foxboro, MA, United States</site_location>
<cordinantes>42.066817,-71.24814</cordinantes>
<site_status>Normal</site_status>
</Marker>
<Marker category="Production"><title lang="en">Yokogawa Japan</title>
<site_location>Shinjuku, Tokyo,Japan</site_location>
<cordinantes>36.543915,136.629281</cordinantes>
<site_status>Critical</site_status>
</Marker>
</Customers>
And this is the JS file containing the function that reads the XML file and enters the data into an array, file is called func.js.
<script src="jquery.xml2json.js" type="text/javascript" language="javascript"></script>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
var markers = [];
$.get('Customers.xml', function(xml) {
var jsonObj = $.xml2json(xml);
$.each(jsonObj.Marker, function(){
var stat = this.site_status == "Critical" ? "redgoogle.png" : "green_marker.png";
var latlng = new google.maps.LatLng (this.cordinantes);
var mark = {
title: this.title,
location: this.site_location,
cord: latlng,
icon: stat
}
markers.push(mark);
});
debugger;
});
And this HTML file that contains the map & should generate two markers according to the content of the "markers" array.
<!DOCTYPE html>
<html>
<head>
<title>Simple Map</title>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">

<script>
markers;
var map;
function initialize() {
var mapOptions = {
zoom: 3,
center: new google.maps.LatLng(32.637929,-16.934395),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"></div>
</body>
</html>
I need assistance in using the data inside the "markers" array in order to generate markets.
How can I use the markers array in order to do that ?
Thanks in advance.
In the Initialize function do this (if your sure the markers have been loaded at this point):
for(var i=0; i< markers.length; i++){
var marker = new google.maps.Marker({ position: markers[i].cord, map:map });
}
If the markers have not been loaded create a function like this:
function AddMarkers(){
for(var i=0; i< markers.length; i++){
var marker = new google.maps.Marker({ position: markers[i].cord, map:map });
}
}
And call this function in the callback of your $.get like this:
$.get('Customers.xml', function(xml) {
var jsonObj = $.xml2json(xml);
$.each(jsonObj.Marker, function(){
var stat = this.site_status == "Critical" ? "redgoogle.png" : "green_marker.png";
var latlng = new google.maps.LatLng (this.cordinantes);
var mark = {
title: this.title,
location: this.site_location,
cord: latlng,
icon: stat
}
markers.push(mark);
});
AddMarkers();
debugger;
});
That will add your markers, for information on how to generate a custom icon refers to
GoogleMaps API Reference
GoogleMaps Icon
You can complete the function AddMarkers to generate the icons and so on

I've created a file that loads markers into a Google Maps JavaScript API canvas.
The markers are generated from an XML file, which get's the markers info from SQL.
I want to be able to call a function ex. loadMarkers() so that I can update the markers position when the SQL data has changed.
As of now, I could call load() again, but then it refreshes the whole map, and not just the markers. Just like a hard refresh of the site..
How can I wrap the code for just inserting markers, so that I can call it back as a function?

create a function (setMarkers) that does the downloadUrl call to load the XML and create markers on the map.
make the map variable global or pass it in to that function
create a global array to track those markers so you can remove them before loading the new ones.
var gmarkers = [];
function setMarkers() {
downloadUrl(urlString, function(data) {
var xml = data.responseXML;
for (var i=0; i<gmarkers.length; i++)
gmarkers[i].setMap(null);
gmarkers = [];
var markers = xml.documentElement.getElementsByTagName("marker");

gmarkers.push(marker);

call that function in the load function and in the setTimeout.
var map;

map = new google.maps.Map(document.getElementById("map"), {

working example
So I have some working code which fetches results from my DB and displays them on a Google map. I also have some code which uses my location to place a marker on a Google map.
My issue is that when I add them together the page loads the results from the DB then I accept geoloaction and it centers the map to my location but doesn't display my marker and also removes the markers for the DB results.
Here is the DB result code:

This is my geolocation code:

Also I get this in the console:
ReferenceError: locations is not defined
for (i = 0; i < locations.length; i++) {
As the ReferenceError already says, you do not have the variable locations defined in your geolocation code.
This code it's not displayed in Google Chrome. Why?
It worked in Firefox.
The code: I'm trying to load from a xml file a set of coordinates+description to
render a map and plot them on it.
And there's a mouse handle to return on screen the coordinates on a mouse click.

You are loading the Google Maps API twice:
<!-- Loading Google Map API engine v3 -->
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script src="http://maps.googleapis.com/maps/api/js?key=MYID&sensor=false">
</script>
You should see the following in the Chrome DevTools console:
Warning: you have included the Google Maps API multiple times on this page. This may cause unexpected errors.
Change your HTML for the API to just one script tag:
<!-- Loading Google Map API engine v3 -->
<script src="http://maps.googleapis.com/maps/api/js?v=3&key=MYID&sensor=false"></script>
I'm sure this is something so basic, but I've been looking at it for an hour, and I can't see it. I'd appreciate a fresh pair of eyes. This is a pretty basic Google Maps API v3 project, copied almost verbatim from the cookbook, which loads data from a MySQL database into an XML file, and then loads data from the XML file into the map.
Here's 3 sample markers from the XML file:
<markers>
<marker name="Total Beverage" type="2" address="9359 Sheridan Blvd Wesminster, CO 80031" lat="-105.053293" lon="39.8658159"/>
<marker name="Union Jack Liquor" type="2" address="1160 S Boulder Road Louisville, CO 80027" lat="-105.1301647" lon="39.9868051"/>
<marker name="Argonaut Wine and Liquor" type="2" address="760 E Colfax Denver, CO 80203" lat="-104.9785574" lon="39.7398985"/>
</markers>
And here's the code that generates the map.

The map centers at the right spot, and zooms to the right level, but the markers don't show up. Thanks for any pointers.
You have the latitude and longitude backwards in your xml:
lat="-105.053293" lon="39.8658159"
Your map is centered at :
var latlng = new google.maps.LatLng(39.909939, -105.078369);
I am pretty experienced when it come to php mysql, but javascript has got me scratching my head. I am trying to add google maps to my website to show where picture in my database were taken. I got the static google map to work, but it will only display 37 markers due to the url character limitations. I followed the tutorial at google maps api docs, and i have a map that will display all the coordinates for the images in my database. My problem is that i cannot for the life of me figure out how to get the map to auto center and auto zoom to fit all of my markers. my test website for my map is at maptest. I found this tutorial on how to auto center/zoom my map by no matter where i put his code i get errors. this is the code i have for my map that does not auto zoom/center:
