Ruby on Rails：如何向 submit_tag 添加确认

Question

<%= submit_tag "Delete" , :confirm => 'Are you sure you want to delete the selected?' %>

doesn't work.

how do I do this?

Answer 1

It should work. Most likely you didn't include necessary JavaScript files. Do you have something like this in your HTML head tag?

<%= javascript_include_tag :defaults %>

Answer 2

尝试这个 ：

<%= submit_tag "Delete", data: { confirm: 'Are you sure you want to delete the selected?' }%>

Answer 3

I found this solution and it works to me.

<%= submit_tag 'Save', onclick: "return confirm('Are you sure?')" %>
