Answer 1

If you want to simulate local JSON data, you need to deploy a server, such as apache. Your ajax also involves cross-domain. It is recommended to experiment in a real environment, or do not cross-domain for the time being. Just pass json first.

Answer 2

dataType changed to json

Answer 3

You need a web server.
