@TheifMaster, thanks for your replay, but if I can re-enable a button, hiding a throbber, etc. in the .done() with a conditional test like : If(jqXHR.status===200) { // Re-enabling button, hiding a throbber, etc. } for example What is the necessity to have .always() function? If so, I think .always() is not necessary and should be removed from JQuery.

@ghaliloo Because always() always runs, while done() only runs if the deferred object is resolved (i.e. the ajax query was successful)

@ghaliloo No, that would only re-enable the button if the request succeeded. ThiefMaster wants to re-enable the button after the request regardless of whether it succeeded or not, and that's the use case for .always().

@ghaliloo There is no requirement to use the always function. If it is not suitable in your case, don't use it.

@Mike, hhhhhhh hhhhhh, No, if it wasn't suitable in my case I wouldn't make a new post about it, in contrary it is very useful for me, since I want to do a task if the Differed is resolved and another if it is rejected and I have to make it in .always() as I said because it is always called, however if I put in .done() or .fail(), I have no warranty it will be executed.
