Answer 1

Under Chrome, using XMLHttpRequest to request the file protocol will be considered cross-domain. You can use Firefox to test, or set up a server

Answer 2

Ajax file request is definitely not possible. Put the project on the server and let the server return header.html.

Answer 3

You can use node to set up a server yourself, and then make requests

Answer 4

load(url,data,function(response,status,xhr))
The url here should be an address that can return a string-like address.
Did you understand it wrong? What does it mean to put header.html? Do you want to return the content of the html file?
