jQuery Ajax not working - meaning of response status code 0
I would like to use a jQuery Ajax function, but for some reason it is not working. I am getting response status code 0. Do you have any ideas why there is status code 0 ?
There are multiple reasons why response status code is 0, but it means that request is not being sent to the server
Possible reasons are:
- Ajax request is not correct (there can be an error)
- Requesting URL is unreachable
- Request is interrupted (for example because browser navigates away from the page)
