Google Maps API: open url by clicking on marker

I want to open a new window by clicking on a marker using Google Maps API 3.

Unfortunately there are not many examples for the Google Maps API and I found out this code:

google.maps.event.addListener(marker, 'click', function() {
    window.location.href = marker.url;
});

How to use it, when I create markers with a loop? I tried it in many ways with no afford.

This is my code – I made it simple and short:

<!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="http://maps.googleapis.com/maps/api/js?sensor=false"></script>

    <script type="text/javascript">
    var points = [
        ['name1', 59.9362384705039, 30.19232525792222, 12],
        ['name2', 59.941412822085645, 30.263564729357767, 11],
        ['name3', 59.939177197629455, 30.273554411974955, 10]
    ];

    function setMarkers(map, locations) {
        var shape = {
            coord: [1, 1, 1, 20, 18, 20, 18 , 1],
            type: 'poly'
        };

        for (var i = 0; i < locations.length; i++) {
            var flag = new google.maps.MarkerImage('markers/' + (i + 1) + '.png',
            new google.maps.Size(17, 19),
            new google.maps.Point(0,0),
            new google.maps.Point(0, 19));

            var place = locations[i];
            var myLatLng = new google.maps.LatLng(place[1], place[2]);
            var marker = new google.maps.Marker({
                position: myLatLng,
                map: map,
                icon: flag,
                shape: shape,
                title: place[0],
                zIndex: place[3]
            });
        }
    }

    function initialize() {
        var myOptions = {
            center: new google.maps.LatLng(59.91823239768787, 30.243222856188822),
            zoom: 12,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(document.getElementById("map_canvas"),myOptions);
        setMarkers(map, points);
    }
    </script>
</head>

How to open url by clicking on marker with code above?

You can add a specific url to each point, e.g.:

var points = [
    ['name1', 59.9362384705039, 30.19232525792222, 12, 'www.google.com'],
    ['name2', 59.941412822085645, 30.263564729357767, 11, 'www.amazon.com'],
    ['name3', 59.939177197629455, 30.273554411974955, 10, 'www.stackoverflow.com']
];

Add the url to the marker values in the for-loop:

var marker = new google.maps.Marker({
    ...
    zIndex: place[3],
    url: place[4]
});

Then you can add just before to the end of your for-loop:

google.maps.event.addListener(marker, 'click', function() {
    window.location.href = this.url;
});

Also see this example.

url isn't an object on the Marker class. But there's nothing stopping you adding that as a property to that class. I'm guessing whatever example you were looking at did that too. Do you want a different URL for each marker? What happens when you do:

for (var i = 0; i < locations.length; i++) 
{
    var flag = new google.maps.MarkerImage('markers/' + (i + 1) + '.png',
      new google.maps.Size(17, 19),
      new google.maps.Point(0,0),
      new google.maps.Point(0, 19));
    var place = locations[i];
    var myLatLng = new google.maps.LatLng(place[1], place[2]);
    var marker = new google.maps.Marker({
        position: myLatLng,
        map: map,
        icon: flag,
        shape: shape,
        title: place[0],
        zIndex: place[3],
        url: "/your/url/"
    });

    google.maps.event.addListener(marker, 'click', function() {
        window.location.href = this.url;
    });
}

the previous answers didn't work out for me well. I had persisting problems by setting the marker. So i changed the code slightly.

   <!DOCTYPE html>
   <html>
   <head>
     <meta http-equiv="content-type" content="text/html; charset=ANSI" />
     <title>Google Maps Multiple Markers</title>
     <script src="http://maps.google.com/maps/api/js?sensor=false"
      type="text/javascript"></script>
   </head>
   <body>
     <div id="map" style="width: 1500px; height: 1000px;"></div>

     <script type="text/javascript">
       var locations = [
         ['Goettingen',  51.54128040000001,  9.915803500000038, 'http://www.google.de'],
         ['Kassel', 51.31271139999999,  9.479746100000057,0, 'http://www.stackoverflow.com'],
         ['Witzenhausen', 51.33996819999999,  9.855564299999969,0, 'www.http://developer.mozilla.org.de']

 ];

var map = new google.maps.Map(document.getElementById('map'), {
  zoom: 10,
 center: new google.maps.LatLng(51.54376, 9.910419999999931),
 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,
   url: locations[i][4]
  });

 google.maps.event.addListener(marker, 'mouseover', (function(marker, i) {
   return function() {
     infowindow.setContent(locations[i][0]);
     infowindow.open(map, marker);
   }
 })(marker, i));

      google.maps.event.addListener(marker, 'click', (function(marker, i) {
   return function() {
     infowindow.setContent(locations[i][0]);
     infowindow.open(map, marker);
     window.location.href = this.url;
   }
 })(marker, i));

    }

     </script>
   </body>
   </html>

This way worked out for me! You can create Google Maps routing links from your Datebase to to use it as an interactive routing map.
