Instance Method Details

#add_confirm_to_attributes_with_facebooker!(html_options, confirm, fun = nil) ⇒ Object

Overrides a private method that link_to calls via convert_options_to_javascript! and also, button_to calls directly. For Facebook, confirm can be a hash of options to stylize the Facebook dialog. Takes :title, :content, :style options. See the Facebook page wiki.developers.facebook.com/index.php/FBJS for valid style formats like “color: ‘black’, background: ‘white’” or like “‘color’,‘black’”.

Examples ==

link_to(“Facebooker”, “rubyforge.org/projects/facebooker”, :confirm=>“Go to Facebooker?”) link_to(“Facebooker”, “rubyforge.org/projects/facebooker”, :confirm=>page says:, :content=>”Go to Facebooker?“) link_to(”Facebooker“, ”rubyforge.org/projects/facebooker“, :confirm=>page says:, :content=>“Go to Facebooker?”, :color=>“pink”)
