ruby-on-rails - rails : Open link in new tab (with 'link_to' )

Question

我有这个代码:

<%= link_to image_tag("facebook.png", :class => "facebook_icon", :alt => "Facebook", :target => "_blank"),                 
            "http://www.facebook.com/mypage" %>

当用户点击链接时，如何在新标签页中打开它？

Answer 1

target: :_blank 参数应该是link_to 的参数，而你把它放在image_tag 参数中。像这样修改您的代码:

<%= link_to image_tag("facebook.png", class: :facebook_icon, alt: "Facebook"), "http://www.facebook.com/mypage", target: :_blank %>

或者用一个 block :

<%= link_to "http://www.facebook.com/mypage", target: :_blank do %>
  <%= image_tag("facebook.png", class: :facebook_icon, alt: "Facebook") %>     
<% end %>
