Jquery 如果用户登录 in/authentication 使用 passportjs 失败时的警告框
Jquery alert box if user log in/authentication fails using passportjs
我目前正在尝试让 jQuery 警告框在用户因未在我的 node/express 应用程序中输入正确的用户名和密码而无法使用护照进行身份验证时弹出。
当发生这种情况时，我确实弹出了一个警告框，但它确实显示了大约 0.5 秒，然后在您可以阅读之前再次消失。但我需要它一直存在，直到用户相应地与它交互，我不确定为什么它不会。
找到我正在使用的内容的参考 here。
我曾尝试使用 connect-flash，但无法使用我找到的所有示例。有什么方法可以让警告框停留而不是出现然后立即消失。

我对 passport 不是很好，因为我最近才开始使用它，如果这是一个简单的问题，我很抱歉......我只需要留下 jQuery 警告框！
任何建议或指导都会有所帮助。
failureFlash 意味着它正在闪烁消息，但我不知道你怎么知道它应该保留多长时间。
也许你应该重定向到 /error#Incorrect Password，并在对话框中显示散列（# 后面的内容）。
