When attempting to call a URL in the background using the following code within a script tag:
var request = new Ajax.Request(logoffURL, {method : 'post'});
I encountered a script error stating Ajax is undefined.
Is it necessary to include any external scripts in order to resolve this issue?
The solution provided in the given code snippet involves leveraging Prototype library. To utilize this code, it is essential to integrate Prototype library into your webpage. One feasible approach is to incorporate Prototype library from Google's CDN as illustrated below:
<script src="//ajax.googleapis.com/ajax/libs/prototype/1.7.1.0/prototype.js"></script>
A necessary step is to incorporate an external script like jQuery and familiarize yourself with conducting ajax calls. The browser does not feature an Ajax object, but it does have XMLHTTPRequest. It is crucial to understand how to utilize it effectively. Check out this resource here for guidance on using XMLHTTPRequest.

Here's an example of how you can implement AJAX in your code:
fetch('https://example.com/data')
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));
For optimal performance, consider using a CDN to load JavaScript libraries like jQuery:
