检查通知是否已检查

Question

I have a javascript code that displays a notification on the home page of my asp.net website.

There is a function that hides the notification when a user clicks "X"; however, when the user browses to other pages and returns back to the home page, the notification is displayed again.

What's the best way to check if the user has already closed that notification the first time they opened the site? Any help is appreciated!

Answer 1

(assuming "back" is back button)

You can do it via 2 ways ( at least)

1) set a cookie when he clicks the X , then when you back , you can check for a cookie flag.

2) You can check the referrer and if the referrer is Page2 , then reponse.redirect to your self , where you'll loose the code which is saved in cache. youll get a new fresh page
