Strange IE6 bug - show/hide select, hemorrhage option innerHTML

We've all had to code up those ever-so-fun branching selects. I chose to implement it by showing or hiding (display:block/none) the container of the label+select corresponding to the appropriate branch. And IE6 decided to hemorrhage option innerHTML onto the page - for 1 of the 3 branches: the middle one. I solved it by adding "position:absolute" to the css for the container.

If

Have you ever seen code like this?

if(condition){
   stuff
}

This won't work for all cases, but I often enjoy writing it like this:

if(!condition) return;
stuff

Note: if you are NOT minifying your code, the bottom method is probably leaner, but if you ARE minifying, stick with the top method.
