我一直在使用 AJAX、JQuery 和 Sessions 很长一段时间。但这是我第一次遇到这个问题。
我正在向另一个页面发送正常的发布请求，并且像我的旧代码一样，我使用目标页面中的会话来测试我的 AJAX 请求是否成功。
在我所做的所有这些时间里，它都运行良好，当然，除非有一些明显的 Javascript 错误阻止我的 AJAX 成功进行。
现在发生的情况是，要使 ajax 请求成功，我需要在关闭并重新打开浏览器后触发它，如果我在发送第一个请求后再次执行它，它将不再成功，另一个有趣的事情是当我启用 AJAX 的错误响应时，我总是会收到一个错误，这真的很烦人，因为我无法确定这个问题的根本原因。
这是服务器问题或代码问题还是我不知道的某些规则？
我的代码不包括包含的 JS：
