- What's this?
id()
public
Generate an HTML id attribute value.
return the <form> element’s id attribute.
<%= form_for @post do |f| %> <%# ... %> <% content_for :sticky_footer do %> <%= form.button(form: f.id) %> <% end %> <% end %>
In the example above, the :sticky_footer content area will exist outside of the <form> element. By declaring the form HTML attribute, we hint to the browser that the generated <button> element should be treated as the <form> element’s submit button, regardless of where it exists in the DOM.
