ruby-on-rails - rails 3, how add a simple confirmation dialog when user clicks a link

Question

what is the easiest way in rails 3 to to ask "Are you sure you want to do that?" when the user clicks on a link?

the link in this case overwrites some data with a new value. It's a simple link_to (GET) back to the same controller method, with a param[] added.

Answer 1

对于像我一样来到这里但使用 Rails 4/5 的人：

link_to "Title", some_path, data: { confirm: "Are you sure?" }

文档

Answer 2

编辑：
<%= link_to "Do something", {:controller => "foo", :action => "bar"}, :confirm => "Are you sure you want to do that?" %>

Answer 3

有一个:confirm选项：

link_to "Visit Other Site", "http://www.rubyonrails.org/", :confirm => "Are you sure?"
# => <a href="http://www.rubyonrails.org/" data-confirm="Are you sure?"">Visit Other Site</a>

你应该有像这个用于 JQuery的不显眼的 JavaScript 驱动程序。设置非常简单。
