Geo Location with HTML5 and Jquery

Last few days I have been working with HTML5 elements, it’s very interesting. This post explains you how to get geo location latitude and longitude values using Jquery. I found a geocode location script from html5demos.com and I have customized bit of code. It is useful you can built foursquare kind of location check out web application.

Geo Location with Jquery

Live Demo     Mobile Live Demo

JavaScript code
Contains Google Map + HTML5 code. Using jquery cookie plugin storing latitude an longitude values $("#check").click(function(){})- check is the ID name of Check-out button.
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/
<script type="text/javascript" src="jquery.cookie.js"></script>
<script type="text/javascript">
function success(position)
var s = document.querySelector('#status');
if (s.className == 'success')
s.innerHTML = "Found you!";
s.className = 'Success';
var mapcanvas = document.createElement('div');
mapcanvas.id = 'mapcanvas';
mapcanvas.style.height = '100%';
mapcanvas.style.width = '100%';
var latlng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var myOptions = {
zoom: 15,
center: latlng,
mapTypeControl: false,
navigationControlOptions: {style: google.maps.NavigationControlStyle.SMALL},
mapTypeId: google.maps.MapTypeId.ROADMAP
var map = new google.maps.Map(document.getElementById("mapcanvas"), myOptions);
var marker = new google.maps.Marker({
position: latlng,
map: map,
title:"You are here!"
$.cookie("MyLat", position.coords.latitude); // Storing latitude value
$.cookie("MyLon", position.coords.longitude); // Storing longitude value
function error(msg)
var s = document.querySelector('#status');
s.innerHTML = typeof msg == 'string' ? msg : "failed";
s.className = 'Fail';
if (navigator.geolocation)
navigator.geolocation.getCurrentPosition(success, error);
error('Not supported'); //HTML Support

//Jquery Code
var lat = $.cookie("MyLat");
var lon = $.cookie("MyLon");
alert('Latitued: '+lat);
alert('Longitude: '+lon);
var url="http://maps.googleapis.com/maps/api/geocode/json?latlng="+lat+","+lon+"&sensor=false";
alert('Google Map API: '+url);
//Get Json Request Here
//HTML Code
<input type='button' id='check' value='Check-out'/>
<div id="status">Loading.............</div>
<div id="map"></div<

Google Geocoding API allowing 2,500 geolocation requests per day so that I dropped Google map JSON parsing with jquery. (Google Maps API Premier allows 100,000 requests per day.)

Sandeep said...

Hi Srinivas

map not displaying in demo only showing Loading...

Srinivas Tamada said...

HTML5 supports Chrome and Firefox latest versions.

Ivan said...

On a PC (Firefox 4) I get some alerts: "Latidude:null", "Longitude:null" and "Google Map API: http://maps.googleapis.com/maps/api/geocode/json?latlng=null,null&sensor=false"
On iPhone 4 I get two "null" alerts
Any clue? Thanks...

You also can use this plugin http://gmap3.net

It manages both JQuery and geo-localisation

<div id="map"></div<

Success: On the PC - Firefox 4, running the demo, I get a top bar that asks to "share location". After clicking the button, the demo pops up the Google Map and finds my exact location (Very Cool!) and I can pull up the Long/Latt.

Fail: If viewing the Mobile Demo on my iPhone, I see the check out box but nothing happens, just get the two null popup boxes.

Enable your browsers cookie storing option

farzin said...

CelLo said...

satyanarayana panchala said...

hi srinivas,
You said that Google not allowing 2500 API requests in a day.But Using JSON Is also any limit in using Google Map?

Please give ...

tareq said...

you are such a life saver. thanks for this. i was searching for this kind of tuts. actually i was trying to load the whole database to get the geo location... it was boring.. thanks again. nice tuts.

ny2244111 said...

Good stuff Srinivas. Can you point me to the documentation which states Google only allows 2500 geolocation requests per client? I found the documentation which talks about 2500 geocoding requests per IP but i've been searching for hours for request limit documentation on geolocation. I know the operation must be expensive on their end but I can't see how they can restrict something like that when it's built into the HTML5 spec.
