JavaScript: Add marker function on Google Map
Problem :
You want to create add marker Javascript function to put markers on Google Map canvas. How to do that?
Solution :
Below is a code fragment from previous tutorial on how to convert IP address to location in Golang.
var map;
function showMap(latitude, longitude, ipaddress) {
var pos = new google.maps.LatLng(latitude, longitude);
var mapOptions = {
zoom: 5,
center: pos,
mapTypeId: google.maps.MapTypeId.ROADMAP,
content: 'Location found by IP Address'
};
var mapDiv = document.getElementById("map-canvas");
map = new google.maps.Map(mapDiv, mapOptions);
var title = ipaddress + " location";
addMarker(map, pos, title, "");
}
function addMarker(map, latlong, title, content) {
var markerOptions = {
position: latlong,
map: map,
title: title,
clickable: true
};
var marker = new google.maps.Marker(markerOptions);
}
Hope this helps and happy coding!
