[javascript] How to change icon on Google map marker

I want to use my customize icon on Google map, and added icon url on the code. But it's still not reflecting on the map. Can anyone suggest, what i am missing here. Why icon is not changing, after adding the icon url "http://google-maps-icons.googlecode.com/files/sailboat-tourism.png".

<script type="text/javascript">
var markers = [
            {
            "title": 'This is title',

            "lng": '145.060508',
        "icon": 'http://google-maps-icons.googlecode.com/files/sailboat-tourism.png',

        var infoWindow = new google.maps.InfoWindow();
        var map = new google.maps.Map(document.getElementById("dvMap"), mapOptions);
        for (i = 0; i < markers.length; i++) {
            var data = markers[i]
            var myLatlng = new google.maps.LatLng(data.lat, data.lng);
            var marker = new google.maps.Marker({
                position: myLatlng,
                map: map,

    }

You have to add the targeted map :

var markers = [
            {
            "title": 'This is title',
            "lat": '-37.801578',
            "lng": '145.060508',
            "map":  map,
            "icon": 'http://google-maps-icons.googlecode.com/files/sailboat-tourism.png',
            "description": 'Vikash Rathee. <strong> This is test Description</strong> <br/><a href="http://www.pricingindia.in/pincode.aspx">Pin Code by 

City</a>'
            }
];

var marker = new google.maps.Marker({
                position: new google.maps.LatLng(23.016427,72.571156),
                map: map,
                icon: 'images/map_marker_icon.png',
                title: 'Hi..!'
            });

apply local path on icon only

we can change the icon of markers, i did it on right click event. Lets see if it works for you...

// Create a Marker
var marker = new google.maps.Marker({
    position: location,
    map: map,
    title:'Sample Tool Tip'
  });


// Set Icon on any event
google.maps.event.addListener(marker, "rightclick", function() {
        marker.setIcon('blank.png'); // set image path here...
});

var marker = new google.maps.Marker({
  position: myLatLng,
  map: map,
  icon: 'your-icon.png'
});

try this

var locations = [
        ['San Francisco: Power Outage', 37.7749295, -122.4194155,'http://labs.google.com/ridefinder/images/mm_20_purple.png'],
        ['Sausalito', 37.8590937, -122.4852507,'http://labs.google.com/ridefinder/images/mm_20_red.png'],
        ['Sacramento', 38.5815719, -121.4943996,'http://labs.google.com/ridefinder/images/mm_20_green.png'],
        ['Soledad', 36.424687, -121.3263187,'http://labs.google.com/ridefinder/images/mm_20_blue.png'],
        ['Shingletown', 40.4923784, -121.8891586,'http://labs.google.com/ridefinder/images/mm_20_yellow.png']
    ];



//inside the loop
marker = new google.maps.Marker({
                position: new google.maps.LatLng(locations[i][1], locations[i][2]),
                map: map,
                icon: locations[i][3]
            });

Manish, Eden after your suggestion: here is the code. But still showing the red(Default) icon.
