Is there's any way how to reset styles back to what's in my CSS?

Example:

```
#foo {width: 50px; height: 50px; position: absolute; top: 150px; left: 250px;}

function moveFoo(newpostop, newposleft){
  $('foo').setStyle({top: newpostop+'px', left: newposleft+'px'});
}

```

Now when I'm done with it, I'd like to move foo back when it was. I know it can be hard-coded, but I need to do this with 25 different divs.

Thanks
