What are Ajax methods?

Ajax( Asynchronous JavaScript And XML) is used to create asynchronous web applications. It is deployed on the client-side and makes use of several web technologies. Ajax has made it easier to asynchronously send and retrieve data from a server without interfering with the existing page’s display and functionality.

Ajax is not a programming language, and it requires a built-in browser with the XMLHttpRequest object, which requests data from the server.

Ajax also uses JavaScript and HTML DOM to display the data.

JQuery Ajax methods

The jQuery library has a full suite of Ajax capabilities. These methods allow a user to load data from the server without refreshing the browser. The following is a list of such Ajax capabilities:

1. .ajaxComplete(): Registers a handler to be called when the Ajax requests are complete. This is an AjaxEvent.

2. .ajaxError(): Registers a handler to be called when the Ajax requests complete with an error. This is an Ajax Event.

3. .ajaxSend(): Attaches a function to be executed before an Ajax request is sent. This is an Ajax Event.

4. .ajaxStart(): Registers a handler to be called when the first Ajax request begins. This is an Ajax Event.

5. .ajaxStop(): Registers a handler to be called when all Ajax requests have been completed. This is an Ajax Event.

6. .ajaxSuccess(): Attaches the function to be executed whenever an Ajax request completes successfully. This is an Ajax Event.

7. jQuery.ajax(): Performs an asynchronous HTTP (Ajax) request.

8. jQuery.ajaxPrefilter(): Handles custom Ajax options or modify existing options before each request is sent and processed by $.ajax().

9. jQuery.ajaxSetup(): Sets default values for future Ajax requests.

Its use is not recommended.

10. jQuery.ajaxTransport(): Creates an object that handles the actual transmission of Ajax data.

11. jQuery.get(): Loads data from the server using an HTTP GET request.

12. jQuery.getJSON(): Loads JSON-encoded data from the server using a GET HTTP request.

13. jQuery.getScript(): Loads a JavaScript file from the server using a GET HTTP request, then execute it.

14. jQuery.param(): Creates a serialized representation of an array, a plain object, or a jQuery object suitable for use in a URL query string or Ajax request. In case a jQuery object is passed, it should contain input elements with name/value properties.

15. jQuery.post(): Sends data to the server using an HTTP POST request.

16. .load(): Loads data from the server and places the returned HTML into the matched elements.

17. .serialize(): Encodes a set of form elements as a string for submission.

18. .serializeArray(): Encodes a set of form elements as an array of names and values.
