Question

目前，我已经达成了一个结论，即HTTP只适用于在线热连接，并且无法通过localhosts或127.0.0.1调用发送，因为每当我的PHP文件创建'http(send)'文件时，无论如何我所在的目录无法调用更新数据库。

我的意思是 index.php调用带有函数onClick()的vote.js vote.js调用带有函数HTTPSend（ERROR）的vote.php vote.php使用服务器XAMPP从mysql更新数据库

我的第一个选择是使用bootstrap和新数据库来尝试rails 我的第二个选择是聘请开发人员我的第三个选择是有人会好好看看，我很乐意通过联系woofwarrior@yahoo.com发送视频演示
