The code use onclick() to initiate a method that use ajax call back to fetch a plugin from the internet, then use it to identify the user location. This program is a user-friendly. Feel free to use it in your system. We will use JavaScript to allow you to implement complex things on web pages. It enables you to create dynamically updating content and add some interactive visual for the user transactions.
