AJAX before and after jQuery 1.8

jQuery AJAX Before Version 1.8.0

Prior to jQuery version 1.8.0, the object returned from jQuery $.ajax() contained functions namely success(), error() and complete().

jQuery AJAX After Version 1.8.0

From jQuery 1.8.0 the $.ajax() function returns a jqXHR object that implements the promises interface (done(), fail(), always() etc.....). The success(), error() and complete() functions are now deprecated.

A quick reminder for those learning:

• The .done() method replaces the deprecated jqXHR.success() method.
• The .fail() method replaces the deprecated .error() method.
• The .always() method replaces the deprecated .complete() method.

jQuery AJAX Before Version 1.8.0 Example

$.ajax({

    url: 'getname1.html',

    dataType: 'html',

    success: function (data, textStatus, xhr)

    {

        console.log(data);

    },

    error: function (xhr, textStatus, errorThrown)

    {

        console.log('error: '+textStatus);

    }

});

$.ajax({

    url: "getname1.html",

    cache: false

})

.done(function(data, textStatus, jqXHR)

{

    console.log(data);

})

.fail(function(jqXHR, textStatus, errorThrown)

{

    console.log('error: '+textStatus);

});
