Docpad:在联系表单上显示错误/成功消息 [英] Docpad : show error/success message on contact form

问题描述

我在docpad.coffee文件中添加了一条处理表单提交的路由，并使用 express-验证程序中间件.现在，根据验证，我想将用户重定向到相同的联系页面，但是在验证成功后显示成功消息(在此我将发送电子邮件)，或显示错误消息.

I added a route in my docpad.coffee file to handle form submissions, that I validate using the express-validator middleware. Now depending on the validation, I want to redirect the users to the same contact page but displaying either a success message when validation is successful (here I'll send an email), or display the error messages.

我没有将验证消息传递给模板以显示它.我尝试了dynamic: true/false，res.locals = validationMessages，res.sessions = validationMessages，res.templateData = validationMessages的几乎所有组合，均未成功.

I didn't manage to pass the validation message to the template to display it. I tried almost all combinations of dynamic: true/false, res.locals = validationMessages, res.sessions = validationMessages, res.templateData = validationMessages with no success.

此外，添加dynamic: true使得对内容的更改根本不会出现，无论我使用什么刷新策略(私有模式，清理缓存，重新启动Docpad，刷新而不缓存等).我应该提交有关此问题的错误.

Furthermore, adding dynamic: true made the changes to the content not appear at all, whatever refresh strategy I use (private mode, cleaning cache, relaunching Docpad, refreshing without cache, etc.). I should probable file a bug about it.

如何?

我正在OS X 10.8.4上使用Docpad 6.53.0(最新)，节点0.10.15

I'm using Docpad 6.53.0 (latest to date), node 0.10.15, on OS X 10.8.4

推荐答案

我通过将哈希值附加到重定向网址(例如:"www.mywebsite.com/#messagesent")上对此作了一点欺骗.然后，我使用客户端javascript读取哈希，然后显示适当的消息.像这样:

I cheated on this one a bit by appending a hash to the redirect url (eg: "www.mywebsite.com/#messagesent"). I then use client side javascript to read the hash and then show the appropriate message. Something like this:

if (location.hash == "#messagesent") {  
    $('#message-sent').show();
    setTimeout(function () {
        $('#message-sent').fadeOut(1000);
    }, 1000);
}

虽然不是你在问什么:)

Not quite what you were asking though :)
