ruby-on-rails-3 – Rails和haml,如何添加id和类选择器到link_to帮助？

我一直在寻找如何添加一个id选择器到link_to帮助使用haml,是可能吗？

a .haml - %a#booked{:href => "index.haml"} Link 1    

  b .html.erb - booking.html.erb - <%= link_to "Link 1",booking_path,:id => "booked" %>

  c .haml.erb - booking.haml.erb - ...??

哪一个相当于哈姆？

解决方法

link_to的工作原理与哈尔同样的方式在erb中.所以这会做你想要的：

= link_to "Link 1",:id => "booked"
#=> <a id="booked" href="/bookings">Link 1</a>

您也可以这样分配一个类属性：

= link_to "Link 1",:id => "booked",:class => "some_class"
#=> <a id="booked" class="some_class" href="/bookings">Link 1</a>

而且,所以对于将id和类传递给link_to毫无疑问,这里是一个例子from the docs：

link_to "Articles",articles_path,:id => "news",:class => "article"
#=> <a href="/articles" class="article" id="news">Articles</a>
