[Javascript] Hide show a TD

[Laurent Muchacho]

Hi 

I just notice something you shouldn't do. Is to use number or a number in
the first character for your variable or the id of your div.
If it work like that nice for you I had some problem long ago with the id of
my div be called 1Div 2Div etc ... and it was fix by doing div1 div2 etc ...

One more thing: Just to make this more readable you should try to set your
instance of that object to a variable:

var objEl = document.getElementById(id)
objEl.style.display = "whatever you want"


>        for (i=1;i<5; i++){
>                if (i!= id){
>                        document.getElementById(i).style.display == 'none';
>                }
>        }

And that's some funky code logic-wise. Are your ID's numbers?
