Additionally, it seems that in the current state all options given to the method are overwritten with the defaults. Changing
options = $.extend({}, options, { timeout: 3000, alert: 'info' });
into
options = $.extend({ timeout: 3000, alert: 'info' }, options);
should preserve user-defined arguments.
The "jQuery.flashMessage.js" javascript no longer works properly if you use latest version (v1.4.0) of jquery.cookie.js! Hopefully someone who knows javascript will post an update :) By the way, great utility I found it very helpful.
I like everything that you've done here but I'm getting an error and I can't seem to figure it out.
'System.Web.Mvc.RedirectToRouteResult' does not contain a definition for 'Success' and no extension method 'Success' accepting a first argument of type 'System.Web.Mvc.RedirectToRouteResult' could be found (are you missing a using directive or an assembly reference?)
I created a folder called, Extensions and I put the FlashMessageExtensions.cs file in there. In my controller I have a reference to "MyProject.Extensions".
Any help would be appreciated.
I updated this for jQuery Cookie Plugin v1.4.0 and Bootstrap 3.0.3 here:
https://gist.github.com/thomkaufmann/a1d301789fc3066ebdd5
Please let me know if there are any remaining issues!
Made some change to show multiple message like below.
return RedirectToAction("DashBoard", "agent").Danger("Danger message.").Success("this is a success").Warning("it's a warning");
whould you please add references.

i can't remove this problem
MohammadSabbir: you have to have using with extension namespace in your controller.
For example, if your FlashMessageExtensions.cs is in namespace Something.Extensions, you have to add using Something.Extensions; in your controller.
The "jQuery.flashMessage.js" javascript no longer works properly if you use latest version (v3.1.1) of jquery! Hopefully someone who knows javascript will post an update :) By the way, great utility I found it very helpful.
I'm using one of the fixes done to the original code (by thomkaufmann) and wanted to know the license terms if the code snippet can be used in other projects.
Thanks
To avoid encoding issues for German Umlauts change the method CreateCookieWithFlashMessage in FlashMessageExtensions to
private static void CreateCookieWithFlashMessage(Notification notification, string message)
{
HttpContext.Current.Response.Cookies.Add(new HttpCookie(string.Format("Flash.{0}", notification), HttpUtility.UrlEncode(message)) { Path = "/" });
}
