Deprecation is the start of the notice we need to give if we are ever to have a hope of removing something. Please do not post code, scripts or snippets.
The function supplied to done is invoked with the Ajax request completes successfully. Why then the post only starts when the ajax code is in the submithandler? However, we shall not discuss that here. I will not explain the details of that in this article. The success callnack receives three parameters viz. This in mind, I still think this is a better way of handling things then returning status and error messages inside the response body.
Also, I have a standard web service methodology that streamlines the response, so that they can be handled uniformly. The function supplied to fail is invoked if the request fails.
