JavaScript bookmarklet to delete all cookies within a given domain

Question

I am testing a web app that writes cookies to subdomain.thisdomain.com and several subfolders within that. I'm looking for JavaScript that I can put into a bookmarklet that will delete all cookies under that subdomain, regardless of the folder in which they exist.

Any ideas?

Answer 1

Derived from my answer here:

javascript:new function(){var c=document.cookie.split(";");for(var i=0;i<c.length;i++){var e=c[i].indexOf("=");var n=e>-1?c[i].substr(0,e):c[i];document.cookie=n+"=;expires=Thu, 01 Jan 1970 00:00:00 GMT";}}(); return void(0);

Due to browser security issues, this will only work when executed while on a page that has access to all the cookies you want to delete.

Answer 2

I would recommend Firecookie extension to Firebug.
