How do I use the Geolocation API in JavaScript?
Asked on Aug 22, 2024
Answer
The Geolocation API in JavaScript allows you to access the geographical location of a device. Here's a simple example of how to use it to get the current position.
<!-- BEGIN COPY / PASTE -->
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(
(position) => {
console.log("Latitude: " + position.coords.latitude);
console.log("Longitude: " + position.coords.longitude);
},
(error) => {
console.error("Error Code = " + error.code + " - " + error.message);
}
);
} else {
console.error("Geolocation is not supported by this browser.");
}
<!-- END COPY / PASTE -->Additional Comment:
✅ Answered with JavaScript best practices.- The code checks if the Geolocation API is supported by the browser using "navigator.geolocation".
- "getCurrentPosition" is called to get the current position, which takes two callback functions: one for success and one for error handling.
- The success callback receives a "position" object containing "coords.latitude" and "coords.longitude".
- The error callback handles any issues, such as user denial of location access.
- Always ensure you handle errors gracefully and inform the user if geolocation is not supported.
