Rails：使用提交的表單中的數據確認消息

[英]Rails: Form confirm message with data from the submitted form

本文翻译自 Kenji Crosland 查看原文 2010-03-02 7684 ruby-on-rails/ javascript/ forms

Trying to make a custom :confirm message for a rails form that returns data from the submitted form--not just a static string.

嘗試創建自定義：確認從提交的表單返回數據的rails表單的消息 - 而不僅僅是靜態字符串。

<% form_for @foo do |f| -%>
<% f.text_field :number_of_bars -%>
<% f.submit :confirm => Are you really sure you want to use ##number_of_bars## bars? -%>

The idea is if the user puts in the number 3 in the number of bars text field the confirm message would show up like this: "Are you really sure you want to use 3 bars?"

這個想法是，如果用戶在條形文本字段中輸入數字3，則確認消息將顯示如下：“你真的確定要使用3個條形碼嗎？”

Any ideas how to do this?

任何想法如何做到這一點？

Try this:

嘗試這個：

<%= f.submit :onclick => "return confirm('Are you really sure you want to use '+
          document.getElementById('number_of_bars_id').value + '?' )" %>

Replace the number_of_bars_id with the id of your field.

將number_of_bars_id替換為您的字段的ID。

If you google a bit you will find a way for this to work with :confirm.

如果你稍微谷歌，你會發現一種方法可以使用：確認。
