Gestione comparsa/scomparsa <div>: come modificare questo JavaScript?

[goat]

Ho risolto usando questo:

var ids=new Array('div1','div2','div3','div4','div5','div6');

function switchid(id){    
    hideallids();
    showdiv(id);
}

function hideallids(){
    for (var i=0;i<ids.length;i++){
        hidediv(ids[i]);
    }          
}

function hidediv(id) {
    if (document.getElementById) {
        document.getElementById(id).style.display = 'none';
    }
    else {
        if (document.layers) {
            document.id.display = 'none';
        }
        else {
            document.all.id.style.display = 'none';
        }
    }
}

function showdiv(id) {
          
    if (document.getElementById) {
        document.getElementById(id).style.display = 'block';
    }
    else {
        if (document.layers) {
            document.id.display = 'block';
        }
        else {
            document.all.id.style.display = 'block';
        }
    }
} 

e l'HTML:

[url="javascript:switchid('div1');"]link01[/url]
[url="javascript:switchid('div2');"]link02[/url]
[url="javascript:switchid('div3');"]link03[/url]
[url="javascript:switchid('div4');"]link04[/url]
[url="javascript:switchid('div5');"]link05[/url]
[url="javascript:switchid('div6');"]link06[/url] 

Funziona!
