jQuery AJAX: $.ajax, shorthand methods, and JSON

Andrew Dorokhov schedule 1 min read

Create an AJAX request (default method is GET):

let ajax = $.ajax({
   url: "/index.php",
   data: {
       name : "Andrew",
       weight : 85
   }
});

Using callbacks:

$.ajax({
    url: "/index.php",
    data: {
        name : "Andrew",
        weight : 85
    },
    success: function() {
        alert("success");
    },
    error: function() {
        alert("error");
    },
    complete: function() {
        alert("complete");
    }
});

Or:

ajax.done(function() {
    alert( "success" );
});

ajax.fail(function() {
    alert( "error" );
});

ajax.always(function() {
    alert( "complete" );
});
