text_field 的类型属性

发布于 2024-08-28 00:47:46 字数 956 浏览 8 评论 0原文

我有这样的代码：

<%= f.text_field :email, :type => "email", :placeholder => "[email protected]" %>

这样人们就可以使用电子邮件键盘而不是 ASCII 键盘在 iPhone 上输入电子邮件。但是，输出是：

<input id="user_email" name="user[email]" placeholder="[email protected]" size="30" type="text" />

应该是：

<input id="user_email" name="user[email]" placeholder="[email protected]" size="30" type="email" />

我也希望将其用于 tel 类型，以便人们获得电话号码键盘。

有没有办法强制Rails使用email类型而不是text，或者我必须直接使用HTML？谢谢

I have this code:

<%= f.text_field :email, :type => "email", :placeholder => "[email protected]" %>

So people can enter their email on an iPhone with the email keyboard instead of the ASCII keyboard. However, the output is:

<input id="user_email" name="user[email]" placeholder="[email protected]" size="30" type="text" />

which should be:

<input id="user_email" name="user[email]" placeholder="[email protected]" size="30" type="email" />

I also want this for the tel type, so people get the telephone number keyboard.

Is there a way to force Rails to use the email type instead of text, or must I use HTML directly? Thanks

使用当前的帮助程序 (http://api. rubyonrails.org/classes/ActionView/Helpers/FormHelper.html)“返回专为访问指定属性而定制的“文本”类型的输入标记...”

我会编写一个帮助程序来使您的代码更好。您可以只使用所需的 HTML 和选项编写一些内容，也可以添加一些内容以与 FormBuilder 一起使用，如下面的代码片段。

module ActionView
  module Helpers
    class FormBuilder
      def tel_field(method, options = {})
        InstanceTag.new(@object_name, method, self, options.delete(:object)).to_input_field_tag("tel", options)
      end
    end
  end
end

It is not possible to do this with the current helpers (http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html) "Returns an input tag of the "text" type tailored for accessing a specified attribute..."

I'd write a helper to keep your code nicer. You could just write something with the HTML and options you need, or you could add something to work with FormBuilder like the snippet below.

module ActionView
  module Helpers
    class FormBuilder
      def tel_field(method, options = {})
        InstanceTag.new(@object_name, method, self, options.delete(:object)).to_input_field_tag("tel", options)
      end
    end
  end
end
