Rails 3:在提交按钮中:disable_with不起作用

Question

在下面的代码中:disable_with不能在rails 3中运行.但它在rails 2.2中完全正常工作

这段代码有什么问题？

<%= submit_tag "Save", :class => "buttons",
                       :disable_with => "Processing",
                       :id => 'save_btn' %>

Answer 1

从版本3.2.5开始,您不应该使用:disable_with.

<%= submit_tag "Save", 'data-disable-with' => "Processing", :class => "buttons", :id => 'save_btn' %>

要么

<%= submit_tag "Save", data: { disable_with: "Processing" }, :class => "buttons", :id => 'save_btn' %>
