This one is fairly self-explanatory, so I’m not going to waste too much time on it.

In short, your switch statements really ought to have a ‘case’ statement. Otherwise they are really just pointless, empty blocks. Take the following:

var x = 0;
switch(x){
    default:
        break;
}

It’s hardly surprising that JSLint is going to complain about this.

The ‘why’ here should be obvious. Clearly you have some redundant code that should be removed or have omitted a chunk for functionality.
