In this tutorial we will create a Get User Coordinates using JavaScript. JavaScript is a scripting or programming language that allows you to implement complex things on web pages. It is widely used in designing a stunning website. It is an interpreted programming language that has a capabilities of Object-Oriented. This code can be used as your calculator to any mathematical problem. So Let's do the coding...

Getting started:

This is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

The Main Interface

This code contains the interface of the application. To create this just write these block of code inside the text editor and save this as index.html.

  11.                 </div>
  12.         </nav>
  13.         <div class="col-md-3"></div>
  14.         <div class="col-md-6 well">
  15.                 <h3 class="text-primary">JavaScript - Get User Coordinates</h3>
  16.                 <hr style="border-top:1px dotted #ccc;"/>
  17.                 <div class="col-md-3">
  18.                 </div>
  19.                 <div class="col-md-6">
  20.                         <button class="btn btn-primary" onclick="getCoordinates()"><span class="glyphicon glyphicon-search"></span> Get Coordinates</button>
  21.                         <br /><br />
  22.                         <div class="alert alert-info">User Coordinates</div>
  23.                         <div class="alert alert-success" style="display:none;" id="display">
  24.                                 <h3>Latitude:<br />
  25.                                         <span id="latitude"></span></h3>
  26.                                 <h3>Longitude:<br />
  27.                                         <span id="longitude"></span>
  28.                                 </h3>
  29.                         </div>
  30.                
  31.                 </div>
  32.         </div>
  33. <script src="js/script.js"></script>
  34. </body>
  35. </html>

Creating the Script

This code contains the script of the application. This code will Get User Coordinates for better use in the layout. To do this just copy and write these block of codes as shown below inside the text editor and save it as script.js inside the js folder.
  1. var latitude;
  2. var longitude;
  3.  
  4. function getCoordinates(){
  5.         document.getElementById('display').style.display = 'block';
  6.         if(navigator.geolocation) {
  7.                 navigator.geolocation.getCurrentPosition(function(a) {
  8.                         latitude = a.coords.latitude;
  9.                         longitude = a.coords.longitude;
  10.                        
  11.                         document.getElementById('latitude').innerHTML = latitude;
  12.                         document.getElementById('longitude').innerHTML = longitude;
  13.                 });
  14.         }else{
  15.                 alert('Geolocation not supported.');
  16.         }
