Does fnFilter('') delete SpryMedia cookies?

DavidBoomer

Probably I'm not asking a reasonable question, but just curious as I am seeing this behavior when multiple datatables have been created across a number of pages.

Thanks,

David

more info... ASP.NET website where some datatables are created from gridviews.

No it doesn't directly - however, the thing to remember is that cookies are limited to 4K - if you have a cookie string which is larger a lot of HTTP servers will reject the request.

As such, DataTables has some "protection" code to try and ensure that the cookie size will never go above 4K. If it does, it deletes the oldest cookie - so it might be that which you are seeing.

One option is to use localStorage ( http://datatables.net/blog/localStorage_for_state_saving ). 1.10 will use localStorage rather than cookies (tough luck to IE6/7 :-) ).

Thanks, Allan. We are at IE8 (gasp), so this might work!

DavidBoomer

will there be an option for sessionStorage as well?

Not built in - but you can use the same basic method as described in the blog with 1.10 but using sessionStorage rather than localStorage.
