JQuery ajax XMLHttpRequest cannot load file

Solution:

This is a cross-origin issue of javascript. It indicates that the domain name initiated by the request is not recognized by the server.

To solve this problem, you can add Access-Control-Allow-Origin = '*' on the server's response or the domain name you need to support.
