Add Popup message To Google Map Pin: HTML5

In this video tutorial we shall teach you how to add a message window(popup) when the pin or the marker is clicked on a Google Map.

JavaScript file
mySript.js

function addMarker(map, googleLatLng, title, content){
 var markerOptn={
position:googleLatLng,
map:map,
title:title,
animation:google.maps.Animation.DROP
 };
 
 var marker=new google.maps.Marker(markerOptn);
 
 var infoWindow=new google.maps.InfoWindow({ content: content, 
                                                position: googleLatLng});
    google.maps.event.addListener(marker, "click", function(){
  infoWindow.open(map);
 });               
}

Add the content and position information to InfoWindow constructor of Google Maps API.
Also add a event listener: once the marker is clicked, open the message window on the map.
