There is a lot of posts about nested Ajax problems, but I can’t figure out whats wrong with my own.

The problem I see is that the server side script doesn’t receive the form values in the nested Ajax call.

On the client side I get that result2 is null.

The nested Ajax code is encapsulated with // problem.

Can anyone see why the nested Ajax doesn’t receive the form values?

$(document).ready(function(){
    $('form').live('submit', function(){

    // ...

    $.ajax({
        type: "GET",
        url: "/cgi-bin/ajax_confirm.pl",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        //      async: false,

        data: $(this).serialize(),

        error: function(XMLHttpRequest, textStatus, errorThrown) { 
        $('div#create_result').text("responseText: " + XMLHttpRequest.responseText +
                        ", textStatus: " + textStatus +
                        ", errorThrown: " + errorThrown);
        $('div#create_result').addClass("error");
        alert("Error occured in ajax.js confirm code.");

        },

        success: function(result){
        if (result.error) {
            $('div#create_result').text("result.error: " + result.error);
            $('div#create_result').addClass("error");
        } else { // server side script says everything is okay

            var users  = $.parseJSON(result.users);
            var owners = $.parseJSON(result.owners);

            $("#dialog:ui-dialog").dialog("destroy");

            $("#dialog-confirm").dialog({
            resizable: false,
            height: 600,
            modal: true,
            open: function() {
                $(this).children('div.dialog-text').replaceWith("<h3><b>Users</b></h3>" + makeDialogTable(users) + "<h3><b>Owners</b></h3>" + makeDialogTable(owners));
            },

            buttons: {
                Okay: function() {
                $(this).dialog("close");
// problem

                        dataType: "json",

                        // generate and send parameters to server-side script
                    data: $(this).serialize(),

                    // script call was *not* successful
                    error: function(XMLHttpRequest, textStatus, errorThrown) { 
                        $('div#create_result').text("responseText: " + XMLHttpRequest.responseText + ", textStatus: " + textStatus + ", errorThrown: " + errorThrown);

                        $('div#create_result').text("result2.error: " + result2.error);
                        $('div#create_result').addClass("error");
                        } else { // perl script says everything is okay

on this line in the problem area

data: $(this).serialize(),

“this” is referring to the dialog itself or possible the ajax

you’ll want to refer to the specific form you are trying to serialize.

i would set the value to a variable and log it to test /see what is going on there

so first figure out what

 $(this)

is by running

alert($(this).prop('id')) // or something similar if your using older jQuery use .attr instead of .prop

EDIT
it doesn’t look like you give the form an id so i’m not 100% sure but i think you can do this

$('form').live('submit', function(){
var aform = $(this)
.....

then in the problam area

 data: $(aform).serialize(),
