Well its all in the title. I'm trying to check the user's password before performing destructive actions:
$.ajax({
type: 'POST',
url: '/path/to/post.json',
data: { password: '**********' },
success: function() { console.log("Success!"); },
error: function() { console.log("Error!"); }
});
In console:
202 Accepted 123ms
Error!
I thought 403 Forbidden for wrong password and 202 Accepted for correct password would be appropriate response codes, but I don't know much about HTTP to be honest.

ajax method lets you set a timeout in milli seconds. When a timeout happens, The fail callback is called, with errorThrown set to "timeout". The request is aborted, meaning that even if the response arrives later on, your done callback is not called by jQuery.
Yes, it is deprecated in jQuery 1.8 onwards. You should use . done() and use . fail() to catch the errors.
The ajaxSuccess( callback ) method attaches a function to be executed whenever an AJAX request completes successfully. This is an Ajax Event.
ajax() function with the default settings, any JavaScript code after this AJAX request will be executed without waiting for a response. In most cases, this is the desired behavior, but there are some situations where you will want to prevent further execution until there has been a response to the AJAX call.
The error callback is not fired due to the status of 202 but due to an error in parsing the response as JSON. For jQuery, 2xx and 304 is a success.
If the response body is Invalid Password that's invalid json and triggers the jQuery error when it tries to parse it. A proper JSON string has quotes around it, like "Invalid Password". You should JSON encode your responses using a JSON serializer, not construct json manually which you can see is error-prone.
