hyperlink

问题 From what I understand, link_to is used for get methods, and button_to is used for post methods. On the other hand, I was told that with HTML5 semantics, <button> is used for any type of clickable...well, button.

问题 How I can submit form with link on correct rails 3 format? Thanks. <%= form_for @post do |f| %> <%= f.label :title %><br> <%= f.text_field :title %> <p><%= f.submit %></p> <% end %> My code sample. 回答1: "Correct" is a tricky word in this context ;) .

问题 Hi, I need help with a class assignment. We were given an HTML file for a pretend business, "Castaway Vacations LLC".

问题 Is there a way to open an asp:HyperLink.NavigateUrl in a new tab and not change location of the current? 回答1: use <asp:HyperLink Target="_blank" /> actually depending on the users settings that may open a new window.
