Geolocation

Hi,

I'm trying to use geolocation in a local weather app, but about 50% of the times it says I'm located in Japan, but I'm actually in Denmark - any idea why this is?

EDIT:

  • It looks like the latitude and longitude is being changed in the XMLHttpRequest (sometimes)
  • comments added
if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(position => {
        const latitude = position.coords.latitude;  // always 57.46
        const longitude = position.coords.longitude; // always 9.99

        const xhr = new XMLHttpRequest();
        xhr.onreadystatechange = () => {
            if (xhr.readyState == 4 && xhr.status == 200) {
                const data = JSON.parse(xhr.responseText);

                console.log(data.coord.lat); // sometimes changed to 35
                console.log(data.coord.lon); // sometimes changed to 139

                const weatherContainer = document.getElementById("weather-container");
                const userLocation = document.getElementById("user-location");
                const weatherIcon = document.getElementById("weather-icon");
                const temperature = document.getElementById("temperature");

                weatherContainer.style.display = "block";
                userLocation.textContent = `${data.name}, ${data.sys.country}`;
                weatherIcon.setAttribute("src", data.weather[0].icon);
                temperature.innerHTML = `${Math.round(data.main.temp)} °C`;
            }
        };
        xhr.open("GET", `https://fcc-weather-api.glitch.me/api/current?lat=${latitude}&lon=${longitude}`);
        xhr.send();
    });
} else {
    alert("Geolocation is not supported in your browser");
}

Log your latitude and longitude to make sure it's identical with your home latitude and longitude.

When I'm logging the data I get from the XMLHttpRequest I get one set of coords, but when I'm logging the coords before the XMLHttpRequest I get the same longitude and latitude no matter if it thinks I'm in Denmark or Japan :-/
