Question

I have this code that works well:

{"livre":"empty_name"}

    $.ajax({
        url: "sent.php",
        type: "post",
        dataType: "json",
        data: formdata,
        success: function (data) {
            switch (data.livre) {
                  case 'empty_name':

                  break;
        }
    });

but when i try this code (i need the id), the case “empty name” didn’t works. The option selected will be the default case:

{"id":"","livre":"empty_name"}

    $.ajax({
        url: "sent.php",
        type: "post",
        dataType: "json",
        data: formdata,
        success: function (id, data) {
            switch (data.livre) {
                 case 'empty_name':

                 break;
        }
    });

Why? and how can be solved? thanks

If I understand correctly with the object up top being the JSON response, I think you want this…

{"id":"","livre":"empty_name"}

$.ajax({
    url: "sent.php",
    type: "post",
    dataType: "json",
    data: formdata,
    success: function (data) {
        var jsonId = data.id;
    }
});

The data parameter of the success callback contains your response (in this case, JSON data). You access your JSON content there.
