Differences: 1, "$.post" is an easy-to-use high-level implementation, while "$.ajax" is the underlying AJAX implementation of jQuery; 2, "$.post" only deals with the post request function to replace the complex "$.ajax", does not support the execution of functions in case of error, otherwise "$.ajax" must be used.

What is the difference between $.post and $.ajax

Ajax is the underlying AJAX implementation of jQuery, and $.ajax is a general underlying wrapper. After requesting data from $.ajax (), you need to use callback functions, such as beforeSend, error, dataFilter, success, complete, and so on.

Get $.post is an easy-to-use high-level implementation. We use the $.get $.post method, and jQuery automatically encapsulates the call to the underlying $.ajax.

Get only handles the simple GET request function to replace the complex $.ajax, and the callback function can be called when the request is successful. Function execution on error is not supported, otherwise you must use $.ajax.

Post only handles post request functionality to replace the complex $. Ajax. The callback function can be called when the request is successful. Function execution on error is not supported, otherwise you must use $.ajax.

$.get ("test.php", {name: "John", time: "2pm"}) $.get method automatically generates queryString and submits it to the server (name=John&time=2pm) upon request

The data submitted by the $.post method is directly similar to a form submission, with a larger amount of data submitted than $.get.

The difference is that get and post further encapsulate ajax, and the effect is exactly the same as the ajax execution type of get or post

The reason why get post does this is to facilitate development, so you don't have to write ajax url scuess every time.

The problems that can be solved by get and post can be solved by ajax, and ajax is more flexible.
