Rails and the <span> tag
提问by Zachary Wright
I'm fairly new to Ruby on Rails, and I'm attempting to create some fancy CSS buttons using the "sliding doors" technique. I have it almost working, but I feel like there has to be a better way to handle the tags for a link.
我是 Ruby on Rails 的新手，我正在尝试使用“滑动门”技术创建一些漂亮的 CSS 按钮。我几乎可以正常工作，但我觉得必须有更好的方法来处理链接的标签。
The way I'm currently doing it:
我目前的做法是：
<%= link_to '<span>New car</span>', {:action => "new"}, :class=>"button" %>
This isn't terrible, per se, but I would like to know if this is the best way to handle span tags in RoR.
这本身并不可怕，但我想知道这是否是在 RoR 中处理跨度标签的最佳方式。

Or you could be pro and use named routes/resources + Haml. That would make it look like:
或者您可以成为专业人士并使用命名路线/资源 + Haml。这将使它看起来像：
%a{ :href => new_car_path }
%span New Car
What you have is fine though..
不过你的东西很好..

If you're still curious, here are some ways to rewrite your code:
如果您仍然好奇，这里有一些重写代码的方法：
Use content_tag:
使用content_tag：
<%= link_to content_tag("span", "New car"), {:action => "new"}, :class=>"button" %>
Use link_towith a block:
使用link_to带块：
<%= link_to {:action => "new"}, :class=>"button" do %>
<span>New card</span>
<% end %>
And of course, you can combine the two by putting a content_taginside the block, but I'll leave it to the reader as an exercise :)
当然，您可以通过content_tag在块内放置 a 来将两者结合起来，但我将把它留给读者作为练习:)
