如何将html id添加到rails form_tag [英] how to add html id to rails form_tag

问题描述

我使用的是Rails 2.2.2，我想向由form_tag生成的html表单代码添加一个id。

 <％form_tag session_path do  - ％> 
 <％end  - ％> 
  

目前产生：

 < form action =/ sessionmethod =post> 
< / form> 
  

希望产生：

 < form id =login_formaction =/ sessionmethod =post> 
< / form> 
  

api 实际上没有任何帮助，我尝试添加

 ：html => {：id => 'login_form'} 
  

没有运气。对于< element> _tag ，您可以直接指定HTML属性，如下：

 <％form_tag session_path，：id => 'elm_id'，：class => 'elm_class'，
：style => 'elm_style'do  - ％> 
 ... 
 <％end  - ％> 
  

它用于< element> _ 远程 _tag 构造您需要将：html map：

 <％form_tag form_remote_tag：url => session_path，：html => {
：id => 'elm_id'，：class => 'elm_class'，
：style => 'elm_style'} do  - ％> 
 ... 
 <％end  - ％> 
  

I am using Rails 2.2.2 and I would like to add an id to the html form code generated by the form_tag.

<% form_tag session_path do -%>      
<% end -%>

Currently produces:

<form action="/session" method="post">
</form>

Would like it to produce:

<form id="login_form" action="/session" method="post">
</form>

The api isn't really any help and I've tried adding various combinations of

:html => {:id => 'login_form'}

with no luck.

解决方案

For <element>_tag you specify HTML attributes directly, as follows:

<% form_tag session_path, :id => 'elm_id', :class => 'elm_class',
                          :style => 'elm_style' do -%>
   ...
<% end -%>

It is for <element>_remote_tag constructs that you need to move the HTML attributes inside a :html map:

<% form_tag form_remote_tag :url => session_path, :html => {
                            :id => 'elm_id', :class => 'elm_class',
                            :style => 'elm_style' } do -%>
   ...
<% end -%>
