关于嵌套的Ajax问题有很多posts，但我无法弄清楚我自己的错误。
我看到的问题是服务器端脚本在嵌套的Ajax调用中没有收到表单值。
在客户端，我得到result2为空。
嵌套的Ajax代码用// problem封装。
有人能看出为什么嵌套的Ajax没有收到表单值吗？
$(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
$.ajax({
type: "GET",
url: "/cgi-bin/ajax.pl",
contentType: "application/json; charset=utf-8",
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').addClass("error");
},
success: function(result2){
if (result2.error) { // script returned error
$('div#create_result').text("result2.error: " + result2.error);
$('div#create_result').addClass("error");
} else { // perl script says everything is okay
$('div#create_result').text("result2.success: " + result.success + ", result2.id: " + result.id);
$('div#create_result').addClass("success");
} //else
} // success
}); // ajax
} else { // if (is_okay) { ...
$('div#create_result').text("Fill out the form to create an activity");
$('div#create_result').addClass("error");
} // else
}, // Okay
// problem
Cancel: function() {
is_okay = 0;
$(this).dialog("close");
}
} // buttons
}); // dialog
} //else
} // success
}); // ajax
// ...
更新 这是HTML，当显示为this

答案 0 :(得分：2)
在问题区域的这一行
data: $(this).serialize(),
“this”指的是对话本身或可能是ajax
您需要参考您尝试序列化的特定表单。
我会将值设置为变量并将其记录下来测试/看看那里发生了什么
所以先找出
$(this)
是通过运行
alert($(this).prop('id')) // or something similar if your using older jQuery use .attr instead of .prop
修改 它看起来不像你给表单一个id所以我不是100％肯定但我认为你可以做到这一点
$('form').live('submit', function(){
var aform = $(this)
.....
然后在problam区域
data: $(aform).serialize(),
