Uncaught TypeError: $.post is not a function

Question

I am getting this error in Console:

Uncaught TypeError: $.post is not a function

for this piece of code:

Answer 1

If you use jquery slim version then this problem will occur. use minified or uncompressed version of jquery js file

Answer 2

You are using the slim version of jQuery, which doesn't include the Ajax methods (in your case $.post()).

Use the non-slim build, available here http://jquery.com/download/, such as:

https://code.jquery.com/jquery-3.5.1.min.js

From jQuery 3.0 release post:

Slim build

[...] Sometimes you don’t need ajax, or you prefer to use one of the many standalone libraries that focus on ajax requests.[...] Along with the regular version of jQuery that includes the ajax and effects modules, we’re releasing a “slim” version [...], it excludes ajax, effects, and currently deprecated code.
