Adding Custom Marker to Google Maps V3 with JavaScript in Website

Jan 19, 2013
Introduction:

Here I will explain how to add custom marker to Google maps api using JavaScript in asp.net website.

Description:


Before add custom marker to Google map in website first we need to get google api key for that please check below url

Once you got the key write the following code in your aspx or html page like as shown below 


<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Add Custom Marker to Google Maps in Asp.net Website</title>
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map_canvas { height: 100% }
</style>
<script type="text/javascript"
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyC6v5-2uaq_wusHDktM9ILcqIrlPtnZgEk&sensor=false">
</script>
<script type="text/javascript">
function initialize() {
var myLatlng = new google.maps.LatLng(13.053147716796578, 80.2501953125)
var mapOptions = {
center: myLatlng,
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP,
marker: true
};
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
icon:'Map-Marker.png',
title: "Chennai"
});
marker.setMap(map);
}
</script>
</head>
<body onload="initialize()">
<form id="form1" runat="server">
<div id="map_canvas" style="width: 500px; height: 300px"></div>
</form>
</body>
</html>
If you observe above code in header section I written code like

<script type="text/javascript"
src="https://maps.googleapis.com/maps/api/js?key=Your_API_Key&sensor=SET_TRUE_OR_FALSE">
Here you need to set key value as your api key and sensor parameter of the URL must be included, it indicates whether this application uses a sensor (such as a GPS locator) to determine the user's location for that reason you must set this value to either true or false explicitly.

To add custom marker to google map we need write the code like as shown below

var marker = new google.maps.Marker({
position: myLatlng,
icon:'Map-Marker.png',
title: "Chennai"
});
marker.setMap(map);
