只有验证消息正在返回，而不是错误消息

时间：2016-11-28 01:03:55

标签： javascript ajax

我正在进行产品页面练习。对于产品页面，如果用户输入格式正确的电子邮件，则会收到验证消息。如果他们输入格式不正确的电子邮件，他们应该会收到错误消息。

产品页面的输入与我的教授在Ruby on Rails中做的事情相关联，自动验证它是否正确格式化。我已成功设法使用当用户输入格式正确的电子邮件时出现验证消息，但我已经能够得到相同的错误消息结果。

当有人输入格式不正确的电子邮件时，它应该是这样的：

当有人输入格式不正确的电子邮件时，这就是它的样子：

当我输入格式不正确的电子邮件时，这是我在console.log中收到的错误：

为什么我的javascript只适用于我的验证邮件而不是我的错误邮件？我做错了什么？根据我的理解，我设置了错误消息以响应服务器的故障，为什么不会出现？

答案 0 :(得分：0)

该站点已连接到Ruby On Rails服务器。服务器自动响应＆＃34;无效的电子邮件地址＆＃34;当放入格式不正确的电子邮件时，但不是验证消息。

我错误地认为服务器没有验证或错误消息，并且我需要为两者创建响应，并且最初隐藏它们并使其根据用户输入改变javascript。因此，此过程仅适用于验证消息，但不适用于错误消息。一旦我删除＆＃34;显示：无＆＃34;从.error-message类的CSS中，问题立即得到解决！
