Obtain the location information upon the loading of the webpage

I am currently in the process of developing a website using HTML, CSS, and JavaScript. My goal is to automatically retrieve the user's location when the page loads, without requiring them to click a button. I would greatly appreciate any assistance with this task.

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

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

Answer №1

To easily retrieve your current location, all you need to do is use the getLocation() method.

<script>
        var x = document.getElementById("demo");
        function getLocation()
        {
            if (navigator.geolocation)
            {
                navigator.geolocation.getCurrentPosition(showPosition);
            }
            else {
                x.innerHTML = "Geolocation is not supported by this browser.";
            }
        }
        function showPosition(position)
        {
            x.innerHTML = "Latitude: " + position.coords.latitude +
            "<br>Longitude: " + position.coords.longitude;
        }
        getLocation()
    </script>

<p id="location"></p>
<script>
 var loc=document.getElementById("location");
        function displayLocation()
         {
        if (navigator.geolocation)
        {
        navigator.geolocation.getCurrentPosition(showUserLocation);
        }
        else{loc.innerHTML="Geolocation is not supported by this browser.";}
        }
        function showUserLocation(position)
        {
        loc.innerHTML="Your current Latitude is: " + position.coords.latitude + 
        "<br>Your current Longitude is: " + position.coords.longitude;  
        }
        displayLocation()
</script>

For those looking to implement this in React without the need for an additional script, here is the ES2015 code snippet tailored for React, eliminating the reliance on the HTML code provided above. Simply import the function. A big shoutout to the original post for inspiring this solution.

const showPosition = position =>{
    let loc = `Latitude:${position.coords.latitude}  logitude: 
    ${position.coords.longitude}`
    console.log(loc)
    return loc
}

const getLocation =  () => {
    if (navigator.geolocation) {
        return navigator.geolocation.getCurrentPosition(showPosition);
    }
    return false
}

Now, you can easily import and utilize the function in your application.

If you are looking to retrieve the state and zip code, leveraging the Google API is a viable option. Below is the code snippet that fetches the geolocation data, sends it to Google, and provides you with the state and address details. Don't forget to enable the Google geolocation API.

//Docs - https://developers.google.com/maps/documentation/geocoding/intro#ReverseGeocoding

const getData = async (url) => {
    let res = await fetch(url)
    let json = await res.json()
    console.log(json);
    return json
}

const showPosition = async position =>{
    let loc = `Latitude:${position.coords.latitude}  logitude: ${position.coords.longitude}`
    let url = `https://maps.googleapis.com/maps/api/geocode/json?latlng=${position.coords.latitude},${position.coords.longitude}&key={GOOGLE_API_key}`
    console.log(loc)

    let address = await getData(url)
    console.log(`results`,address)
    return address
}

const getLocation = async () => {
    if (navigator.geolocation) {
        return navigator.geolocation.getCurrentPosition(showPosition);
    }
    return false
}
