Front End (Beginners): Check if an AJAX request is made

First Published: .

I created this little video to show how to use the Web Developer Tools to check if jQuery AJAX request is being made.

This is to help beginners in their journey learning to program Front End.

Please be aware that the page I used makes their own calls for marketing purposes. I cleared several times the history to show what is the real AJAX request we are doing.

Note: The recording program did not capture correctly the mouse position and this video has no sound.

The page I shown is:

And some more info about jQuery .ajax method:

Normally you can try your HTML and JavaScript from your browser, opening the HTML file. However there are Security restrictions when it applies to AJAX requests or trying to access a local file from the browser.

You’ll need to run your JavaScript from an HTML page server from a Web Server. You can install apache if you use Linux, or WAMP if you use Windows or MAMP (Mac Apache MySQL PHP) if you use Mac or if you know how to you can create a Docker Container.

When you’re programming and your code does not trigger, pay attention to errors:
