.ajax calling "error" when status = 200 but response is null

Reported by: Owned by:

I just upgraded from 1.8.2 to 1.9.1 and found that if the response to a ajax call is null (empty) jquery fires the "error" handler. This did not happen in 1.8.2. I am using this to change some settings on the server and there is no response needed to the call.

success: function(msg) {

if (callback != null) {




error: function(msg) {

alert("Failed to load!");

Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket!

Additionally, be sure to test against the "jQuery 1.x (edge)" or "jQuery 2.x (edge)" version to ensure the issue still exists—you may need to change this to a specific version depending on the test case.

For the AJAX-related tests you can create a few fiddles and submit requests to addresses with "/show/light" added to the end of the URL; example:

To get you started, use the appropriate boilerplate:
