There was a problem, then a quick idea, afterwards came implementation (20 mins;).

When you are writing something into webform, there are number of possible ways, you can lose content. Browser hangs, system hangs, you accidentally go away from page, etc. And you start swearing.

Here you can find (and test) my implementation of autosave for form element's values. No further explanations, code is simple. Just do view-source.

Tested on IE, Mozilla (Phoenix) and Opera. Surprisingly manual save/load/clear works even in Netscape Navigator 4.08. Strange. Completely scary...

Available methods cc.load(), cc.save(), cc.clear(), cc.start(), cc.stop()

If you have any comments on this one, just go there (don't fear latvian language:)
