Since I am new to web development, I am confused about the difference between 'ajax' and 'http' request. What's the difference between those two and are they on the same par?

- 2In short, ajax makes a http request and while it is waiting for it to return, uses javascript to make it look like it's doing something. So ajax is something that uses httpNick.Mc– Nick.Mc2019-02-17 12:28:48 +00:00Commented Feb 17, 2019 at 12:28

I know this is an old question, but I'll type this down anyway for anyone who comes across.
Simply put, HTTP is the protocol (procedure of communication) that both the web server and the web browser understand. With both AJAX and non-AJAX requests, the browser sends HTTP requests and receives HTTP responses from the web server.
Deference between an AJAX request and a non-AJAX request is that, AJAX requests:
- work in the background seamlessly, and
- don't make the pages to reload every time a response is received.
while the non-AJAX requests load/reload the web page every time a response is received.

jQuery's ajax() sends the data with Content-type: x-www-form-urlencoded
Angular's $http sends the data with Content-type: application/json
Your server obviously expects JSON, but you set up the $.ajax() call incorrectly for that
- The method property doesn't seem to exist.
- The type property is supposed to determine the type of the request (e.g. 'GET', 'POST' etc).
- In order to change the default content-type to application/json you can use the contentType property.
