如何使用Ruby on Rails创建类似这样的模式弹出窗口？

Question

I want to get a modal popup almost like the ones you see when you send a message on Facebook or when you sign up to say the newsletter on www.gemvara.com in my own Ruby on Rails application.

The idea is someone signs up for a newsletter, and I give them a very friendly inline modal popup saying thanks for subscribing, etc.

How do I go about doing that with Ruby on Rails? Do I have to use ActionView? Do I write it in pure JavaScript and not bother doing it in Rails? How do you Rails experts suggest I do this the cleanest way possible using Rails 2.3.8.

I've found plugins that does this in jQuery, does that mean I should load jQuery AND Prototype which is Rails default javascript library of choice? Seems like a waste of network bandwidth to load both.

Answer 1

Modal dialogs are accomplished via JavaScript. Your rails app may provide the data, form, whatever that is displayed in the dialog, but you are doing a lot of the work in JavaScript. I would recommend taking a look @ the jQuery UI project. Here is a link directly to their modal dialog widget: http://jqueryui.com/demos/dialog/

Have fun!

另外，如果您不使用jQuery，则有一个名为Redbox的rails插件，尽管我已经有一段时间没有使用它了，但是如果您使用的是默认JS，它还可以创建模态并使用Prototype。库。
