在用户通过 AJAX 提交注册 HTML 表单后，我创建的一些 jQuery 通知存在问题，这些通知是基于从 PHP 文件中回显的信息触发的。错误通知有效，但不能成功发布到数据库。我知道应该显示成功通知，因为数据经过验证并写入数据库并且 AJAX 发布成功。但是，成功通知不想工作。这种技术性的原因可能是什么？
我有以下设置：
signup.html（在页面中包含以下 ajax*）：
function registerUser(formKey) {
$.ajax({
type:"POST",
url:"engine/new_user.php",
data: $("#"+formKey).serialize(),
cache:false,
success: function(data) {
if(data == -3){
$("html, body").animate({ scrollTop: 0 }, 600);
$("#user-exists-notification").fadeIn(1000);
}
if(data == -4){
$("#account-created").fadeIn(1000);
}
if(data == -1){
$("html, body").animate({ scrollTop: 0 }, 600);
$("#fields-complete-notification").delay(1000).fadeIn(1000);
}
if(data == -2){
$("html, body").animate({ scrollTop: 0 }, 600);
$("#pw-confirm-notification").delay(1000).fadeIn(1000);
}
},
error: function(data) {
}
});
}
新用户.php
require("register-classes.php");
$register=new Register($_POST['fname'], $_POST['lname'], $_POST['email'], $_POST['sex'], $_POST['birthdate'], $_POST['phone'], $_POST['country'], $_POST['alias'], $_POST['handle'], $_POST["password"], $_POST["cpassword"], $_POST['network']);
if($register->checkFields()== false){
echo -1;
