How to handle POST 500() error in catch block?

Question

JavaScript

All good.
Sometimes, during the execution of the script, you can catch the POST 500 () jquery.js:1 error, after which the execution stops.
How should it be processed so that the script continues to work?

Answer 1

on Ajax-events "error" or "ajaxError" hook error handler functions
i.e. type repeat the request
or display an error somewhere
