Is there? I don't know. I've been hitting my head against a brick wall with ways to possibly do this without using a server-side language.
So far my code runs well locally as well as on a server - I'd rather not have to use a server-side language.
Well, there's the challenge. First one with a correct answer wins.... uh... points.
(Oh, and I'm not asking for code examples before anyone flames me - just a simple nod in the right direction would be grand)
Cookies or HTML5 databases. The latter has the benefit of not adding overhead to every network request you make, and it's managed separately from cookies and responds to a query language, rather than a simple key value store.
There is a good solution I'm using currently for persistence, it's a jQuery plugin called jStore with nice and easy api. Here it is http://twablet.com/docs.html?p=jstore
It supports all modern browsers and even can fall back to flash-based storage option. So it's fully transparent for you to write your code putting and popping up your data by key. It's basically a key-value persistent storage.
depending on how much data you are looking to store, you can store it in a cookie.
html5 gets a local storage db called webstorage this is already implemented in cromium and in safari. Very small amounts of data could also be stored in a cookie
