def (options = {},&proc)
   js = capture(&proc)
   text = options.delete(:text)
   concat(content_tag("fb:login-button",text,options.merge(:onlogin=>js.to_str)))
end

#fb_login_and_redirect(url, options = {}) ⇒ Object

Render an <fb:login-button> element, similar to fb_login_button. Adds a js redirect to the onlogin event via rjs.

Examples

fb_login_and_redirect '/other_page'
=> <fb:login-button onlogin="window.location.href = &quot;/other_page&quot;;"></fb:login-button>

Like #fb_login_button, this also supports the :text option

fb_login_and_redirect '/other_page', :text => "Login with Facebook", :v => '2'
=> <fb:login-button onlogin="window.location.href = &quot;/other_page&quot;;" v="2">Login with Facebook</fb:login-button>
