[SOLVED] Accessing data sent from done event in a ajax request?

in Getting Started • 7 years ago

Hi,
imagine you have the next ajax call:

$.ajax({
                    type:'POST',
                    async:false,
                    url:'../../NectarUI/Functions/updatvalii.php',
                    data: {ala:idal,lat:$('#ubilat').html(),lon:$('#ubilon').html(),calle:$('#ubicalle').html(),numero:$('#ubipiso').html(),ciudad:$('#ubiprovi').html(),pais:$('#ubipais').html(),ag:$('#codagente').attr('name'), piso: $("#editPiso").val()}

                }).done(function(res, st, xhr) {
                    console.log(res);
                    llenaDescGeneral('descgencp', '');
                }).fail(function(xhr, st, err) {
                    console.log(xhr);
                });

The question is: I'd loke to get the data json string that I've sent to the ajax request but in the done or the fail callbacks. Is this possible? Or I must to declare it outside the ajax function?
Many thanks!

async:false,

Screws up everything. Espcially .done and .fail ! Don't do it. In the future you may not be able to do it!

Forget the async to false, the problem I got is that I'd like to get the data json object inside done methods. In my case is mandatory to use async to false, due another function is waiting for this process to be executed before begins the new functionality.

async (default: true)

Type: Boolean

By default, all requests are sent asynchronously (i.e. this is set to true by default). If you need synchronous requests, set this option to false. Cross-domain requests and dataType: "jsonp"requests do not support synchronous operation. Note that synchronous requests may temporarily lock the browser, disabling any actions while the request is active. As of jQuery 1.8, the use of async: false with jqXHR ($.Deferred) is deprecated; you must use the success/error/complete callback options instead of the corresponding methods of the jqXHR object such as jqXHR.done() or the deprecated jqXHR.success().

The problem is not that, my request works fine, the problem is that I want to access to the data json object inside the done method, that's my only problem.

Your done method is not called when you use async:false.

I think you're wrong, my method done is calle successfully all the time, at least with firefox and chorme. But imagine I use aync true, and I try to access to the data object, is this possible?

It is passed as the first parameter of the done callback. Unless there was an error, in which case .fail is called.

No, res is the data got from the php file updatvalii.php, not the data sent to the callback...

You mean {ala:idal,lat:$('#ubilat').html(),lon:$('#ubilon').html(),calle:$('#ubicalle').html(),numero:$('#ubipiso').html(),ciudad:$('#ubiprovi').html(),pais:$('#ubipais').html(),ag:$('#codagente').attr('name'), piso: $("#editPiso").val()}?

Save it in a variable. jQuery does not keep it.

YES! That's just the thing I wanted to know!
I wanted be sure if there's no other ways to done it, and unhopefully I see that no... I thought that using a key of xhr returned object, was possible to acces to the headers sent, but seems no.
Then I must use a variable to store it outside the $.ajax() method.
Many thanks JAKE!
