How do I keep my HTML page from automatically resetting itself after javascript modifies it?

I have an HTML document that is modified based on javascript actions modifying the DOM. For some reason, the last action is to reset the page, so the changes don't persist. I don't understand why.

all changes happen inside the page. they never get out to your disk or the server... UNLESS you store your changes in a cookie or use ajax tricks to save them back on the server.





a simple thing, like which part of the dom you are showing can be done by modifying the hash part of the url (like a normal %26lt;a href="#somewhere"%26gt; and when the page is loaded you look at the hash and re-modify the dom!
