How to Serialize Form Data in JavaScript without Frameworks?

Form Serialization in JavaScript without Frameworks

In the realm of JavaScript, developers may encounter the need to serialize form data to transfer it to a server or perform other operations. While frameworks like jQuery provide convenient methods for form serialization, there are scenarios where a lightweight, framework-independent approach is preferable.

One solution is to leverage the built-in FormData object. introduced in HTML5, FormData provides a convenient way to collect and serialize form data. To use it:

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

This creates a FormData object containing all of the data from the form elements. You can then send this object using the XMLHttpRequest object:

<code class="javascript">const request = new XMLHttpRequest();
request.send(params);</code>

Note that FormData is primarily designed for POST requests. For other request methods, you may need to use a library or implement your own serialization logic.
