How to Serialize a Form without Using a Framework

When working with web forms, it's often necessary to gather and send the form data to a server for further processing. JavaScript provides built-in methods to accomplish this task without the need for external libraries or frameworks.

Using FormData (2023 Update)

In recent versions of JavaScript, the FormData API allows for easy form serialization. Here's an example:

<code class="javascript">const form = document.querySelector('form');
const params = new FormData(form);
const request = new XMLHttpRequest();
request.send(params);</code>

This approach is straightforward and works particularly well for POST requests.

Note: This method may not be supported in older browsers or when performing GET requests.
