我有一个简单的文件上传表单，只有当我从表单html文件中删除ajax脚本时才能正常工作。如果没有提交，我将被带到一个空白页面，显示正确的错误或成功消息（它应该像验证一样）。文件上传和PHP验证仅适用于不使用ajax文件
如果我包含它，它会绕过我所有的参数并跳到最后一个错误。在那里说你必须上传一个文件才能继续。
在我的ajax文件中是否存在缺少的东西？我无法弄清楚为什么它跳过我所有的验证。
感谢您的帮助，您可以给

[你看了在浏览器的开发者工具的AJAX请求/响应？你有没有在项目中包含jQuery库？是否有任何错误报告？你在网络服务器上运行这个吗？]（http://jayblanchard.net/basics_of_jquery_ajax.html） –
感谢您的回复， – bilcker
感谢您的回复，没有错误，我已经包含了jquery库。是的，我正在服务器上运行，并且当我在开发人员工具中查看响应时，我所得到的仅仅是和响应上传的对象：“您必须上传文件才能继续。”有没有更好的方法来审查答复？ – bilcker
