Und hier ist meine Version basierend auf @emzero, mit Änderungen, um mit jQuery zu arbeiten, getestet auf Rails 3.2
application_controller.rb
class ApplicationController < ActionController::Base
protect_from_forgery
after_filter :flash_to_headers
def flash_to_headers
return unless request.xhr?
response.headers['X-Message'] = flash_message
response.headers["X-Message-Type"] = flash_type.to_s
flash.discard # don't want the flash to appear when you reload page
end
private
def flash_message
[:error, :warning, :notice].each do |type|
return flash[type] unless flash[type].blank?
end
end
def flash_type
[:error, :warning, :notice].each do |type|
return type unless flash[type].blank?
end
end
end
application.js
// FLASH NOTICE ANIMATION
var fade_flash = function() {
$("#flash_notice").delay(5000).fadeOut("slow");
$("#flash_alert").delay(5000).fadeOut("slow");
$("#flash_error").delay(5000).fadeOut("slow");
};
fade_flash();
var show_ajax_message = function(msg, type) {
$("#flash-message").html('<div id="flash_'+type+'">'+msg+'</div>');
fade_flash();
};
$(document).ajaxComplete(function(event, request) {
var msg = request.getResponseHeader('X-Message');
var type = request.getResponseHeader('X-Message-Type');
show_ajax_message(msg, type); //use whatever popup, notification or whatever plugin you want
});
Layout: application.html.haml
#flash-message
- flash.each do |name, msg|
= content_tag :div, msg, :id => "flash_#{name}"
