问题描述

我想在使用 Ruby 的 link_to 函数上添加确认消息.

I wanted to add confirmation message on link_to function with Ruby.

= link_to 'Reset message', :action=>'reset' ,:confirm=>'Are you sure?'

任何想法为什么它不起作用?

推荐答案

首先，您应该验证您的布局是否具有 jquery_ujs.最佳做法是将其包含在您的主 application.js 中:

First, you should verify that your layout have jquery_ujs.Best practice to do it by including it in your main application.js:

//= require jquery_ujs

检查您是否在布局中包含了 application.js:

Check that you included application.js in your layout:

= javascript_include_tag :application

在开发模式下，查看源 html 并验证 jquery_ujs.js 是否存在.

While, in development mode, view your source html and verify jquery_ujs.js exists.

运行您的服务器并验证您的链接标签是否具有 data-confirm 值，例如:

Run your server and verify your link tag has data-confirm value, for example:

<a href="/articles/1" data-confirm="Are you sure?" data-method="delete">

如果所有这些步骤都正确，一切都应该正常！

If all those steps are correct, everything should work!
