添加自定义类以形成字段 [英] Add custom class to form fields

问题描述

具有这种形式

 <％= form_tag'search'，方法：'get'，class：'form-水平'do％> 
 <％= label_tag：搜索，'在此处输入网址'％> 
 <％= text_field_tag：search％> 
 <％= submit_tag'Get it！'％> 
<％end％> 
  

上面的代码增加了 class ='form-horizo​​ntal' class ='form-control 'b


解决方案

试试这个：

  text_field_tag：search，nil，class：'form-control'
  





以备参考：





  text_field_tag（name，value = nil，options = {}）
 
 text_field_tag：search 
＃=> < input id =searchname =searchtype =text/> 
 
 text_field_tag：搜索，'在此处输入您的搜索查询'
＃=> < input id =searchname =searchtype =textvalue =在此输入您的搜索查询/> 
 
 text_field_tag：search，nil，class：'form-control'
＃=> < input class =form-controlid =searchname =searchtype =text/> 
  




Having such form

<%= form_tag 'search', method: 'get', class: 'form-horizontal' do %>
     <%= label_tag  :search, 'Enter url here' %>
     <%= text_field_tag :search  %>
     <%= submit_tag 'Get it!' %>
    <% end %>

Code above adds class='form-horizontal' for form tag.

How can I add class='form-control' for each input field ?

解决方案

Try this:

text_field_tag :search, nil, class: 'form-control'

For future reference:

text_field_tag(name, value = nil, options = {})

text_field_tag :search
# => <input id="search" name="search" type="text" />

text_field_tag :search, 'Enter your search query here'
# => <input id="search" name="search" type="text" value="Enter your search query here" />

text_field_tag :search, nil, class: 'form-control'
# => <input class="form-control" id="search" name="search" type="text" />
