有没有一种方式与铁路形式助手产生一个按钮标签提交 [英] Is there a way with rails form helper to produce a button tag for submit

问题描述

我正在尝试创建按钮ala Wufoo（重新发现按钮元素 ）

我想写下如下代码：

 <％form_tag search_path，：method => ：get，：class => 'search'do％> 
 <％= text_field_tag：search，params [：search]  - ％> 
 <％= button_tag'search'，：name =>零 - ％GT; 
<％end％> 
  

生成以下HTML（而不是输入[type =submit] tag） p>

 < button type =submitclass =positive> 
< img src =/ images / icons / tick.pngalt =/> 
保存
< /按钮> 
  

方法已经存在吗？或者我应该推出自己的帮手？

解决方案

您可以使用content_tag来实现此目的。这是做你想做的更有道理的方式。但它比原始HTML长。

 <％content_tag：button：type => ：submit，：class => ：正面做％> 
 <％= image_tag图标/ tick.png％> 
保存
<％end％> 
  

其中产生

 < button type =submitclass =positive> 
< img src =/ images / icons / tick.pngalt =Tick/> 
保存
< /按钮> 
  

然而，以此为出发点，您应该没有问题自己动手使用强大的助手，或者将其抽象化到部分。

I am trying to create buttons ala Wufoo (Rediscovering the button element)

I would like to write the following code like the following:

<%form_tag search_path, :method => :get, :class => 'search' do %>
  <%=text_field_tag :search, params[:search] -%>
  <%=button_tag 'search', :name => nil-%>
<%end%>

To generate the following HTML (instead of the input[type="submit"] tag)

<button type="submit" class="positive">
    <img src="/images/icons/tick.png" alt=""/> 
    Save
</button>

Does a method exist already? Or should I roll my own helper?

解决方案

You could use content_tag to achieve this. It's the more railsy way of doing what you want. But it's longer than the raw HTML.

<% content_tag :button :type => :submit, :class => :positive do %>
   <%= image_tag "icons/tick.png"%>
   Save
<% end %>

Which produces

<button type="submit" class="positive">
    <img src="/images/icons/tick.png" alt="Tick"/> 
    Save
</button>

However using this as a starting point you should have no problem rolling your own robust helper, or abstracting it to a partial.
