Javascript populating section on page based on cookies

[lleemon]

I have a page that uses asp to provide a list of items. I want to create a server side include that when I click on an item it adds the item to a list of cookies, save the list, and then displays the list in another section on this same page in another table.

I have figured out that javascript can save cookies with out refreshing the page unlike asp. I don't know how I will be able to populate the cookie data into another section of a table. It will be like a chart on the right/left side of a web page that displays all the items I have in my cookie. Do I need to create a form in this table section and then somehow populate it?

Thanks for any help/advice you give.

Why do you want to use cookies to transfer values between different parts of a page? You can better use javascript variables for this. Imo cookies should only be used to store variables across different sessions.

You post a good question. I want to put to a cookie because if they do leave and come back the next time they will have the same selections they had last visit. Plus, I have thought of both session variables and having them sign up to create entries into the database. Session variables take resources from the server so if a large number of users are on then the box takes a hit. Writing to a database could take time depending on the amount of users that I get. Yes, you probaboy are thinking I will never get to the size of say ebay, amazon etc.. but I believe if I can get this to work then it would serve the best for performance.

So I guess if you have some ideas for me that would be great on how to do this with cookies.

Thanks.

I'm sorry, I've never worked with javascript cookies, and my knowledge about ASP cookies has worn down very much. I can't help you with it.
