How to Detect User Location using Javascript
Hello friends, today in this blog, we will learn how to detect user location using javascript. In our previous blog, we saw how to create a Custom Card Slider Using HTML, CSS, Javascript, and Owl Carousel Plugin. Now it's time to create a user location detector. I've also shared many projects related to Javascript. So don't forget to check here.
In order to get the location of the user, we can use the Geolocation API of JavaScript which returns the geographical position of the user. Using this API we can get the current latitude and longitude coordinates of the user if they allow it. In this small project (How to Detect User Location using Javascript), on the webpage, there is a box that has an icon and button.

- Cookie Consent Box Design
When you click on that button, there will open a location prompt with allow and block options. If you block the request then the button text will change to You denied the request. If you allow the request then there will show detecting your location. After a few seconds, there is shown your current location including city, postal code, state code, and country.
In the console of a browser, youll get many other location details including road, municipality, continent, etc. If youre feeling difficulty with what Im saying then you can watch a demo video or full video tutorial of it.
