AJAX POST Requests with XHR

Using the XMLHttpRequest Object

The XMLHttpRequest (XHR) object allows you to make HTTP requests from JavaScript, enabling asynchronous communication with web servers. Using XHR, you can send POST requests to submit data to a server without refreshing the entire page.

Steps to Perform an AJAX POST Request

1. Create an XHR object: const xhr = new XMLHttpRequest();
2. Open a request (specify the request type and URL): xhr.open('POST', 'URL');
3. Configure the request (e.g., headers, body): xhr.setRequestHeader('Content-Type', 'application/json'); xhr.send(JSON.stringify({ data: 'data' }));
4. Handle the response: xhr.onload = function() { ... }

By following these steps, you can perform AJAX POST requests and communicate with remote servers efficiently from your JavaScript code.
