Geo location in JavaScript

Hi everyone,

In this tutorial I am going to let you guys know about how you can get live location of the user. To do so I am going to use javascript geolocation method.

This Javascript method is not supported by all the browser.

So here is a list of brows support JS geolocation.

  1. Chrome 5.0 & above
  2. Mozilla firefox 3.5 & above
  3. Safari 5.0 & above
  4. Opera 6.0 & above
  5. IE 9.0 & above

So please check yours browser version first before getting started with the geolocation API.

Now lets start with the coding part:

getCurrentPosition() method is used to get user’s current location.

In the location part we will get only long and lati from the javascript code.

function getLocation() {
    if (navigator.geolocation) {
    } else {
        x.innerHTML = "Geolocation is not supported please update your browser";

So in the above part I have created new function for getting user’s location.

You can see i have used variable named x in the above code this is basically for the output where I am going to show my output.

So let’s start with the coding part for getting user’s location from the javascript code.

function showPosition(position) {
    x.innerHTML = "Latitude: " + position.coords.latitude + 
    "<br>Longitude: " + position.coords.longitude; 

Now in the above code I have used x variable again to output my data into the html code.

Moreover, I can say we only need to call this function from button or with js to get user’s location.

After this there are some more methods to handle different errors.

function showError(error) {
    switch(error.code) {
        case error.PERMISSION_DENIED:
            x.innerHTML = "User denied the request"
        case error.POSITION_UNAVAILABLE:
            x.innerHTML = "Location information is not available."
        case error.TIMEOUT:
            x.innerHTML = "Request time out"
        case error.UNKNOWN_ERROR:
            x.innerHTML = "An unknown error occurred."


You can see in the above code there are 4 type of errors available in the geolocation system.

  1. Permission Denied: Whenever our code run in the browser user will be asked for the permission to get their location if user decline for the same we can show this error to the user.
  2. Position Unavailable: Sometimes user’s location will not be able to determine by the browser so in that case we can show them error for the same.
  3. Timeout : Timeout error will shown when request takes longer than usual time for the response.
  4. Other error : There are many reasons where we can’t get user’s location with the js code so rest all the errors are shown with this.

Now there is a final code for getting user’s long and lat from Javascript.

<!DOCTYPE html>
<p>Click the button to get your coordinates.</p>
<button onclick="getLocation()">Try It</button>
<p id="demo"></p>
var x = document.getElementById("demo");
function getLocation() {
if (navigator.geolocation) {
} else {
x.innerHTML = "Geolocation is not supported by this browser.";
function showPosition(position) {
x.innerHTML ="Latitude: "+ position.coords.latitude +
"<br>Longitude: "+ position.coords.longitude;

Output for the same code will as follow :

So that’s al for today guys stay tuned for my further updates.
