如果if / else语句啊美女啊。我认为你的语言声明可能会妨碍你...你基本上是在说电子邮件是无效的，把它设置为红色，检查语言&给用户一条消息......然后将其设置为黑色。它在盲目的情况下做到了这一切。


此外，来自潜在用户填写表单的消息：如果我在我的电子邮件中犯了错误，我不想将其替换为错误消息，我想看到输入旁边的错误信息....无论如何，我已经用投掷者替换了它的那一部分。功能，您可以自己编写 - 并且可以包含语言声明


试试这个：

ah the beauty if the if/else statement. I think your polish language statement might be getting in the way..... you''re basically saying if the email is invalid, set it to red, check the language & give the user a message... then set it back to black. it does all this in the blind of an eye.

Also, a message from a potential user filling out your form: "if i made a mistake on my email, I don''t want to have it replaced with an error message, I want to see an error message next to the input".... anyway, i''ve replaced that part of it with a "thrower" function, which you can write yourself -- and can include the language statements

我尝试了这个为什么然后表单转到动作文件我的意思是返回false不起作用

i tried this why but then the form goes to the action file i mean that the return false doesnt work
