caucAll( document.getElementsByClassName('dices') , document.getElementsByClassName('view') , document.getElementsByClassName('sumary') , $('total') );
以上可以寫成：
caucAll( $$('.dices'), $$('.view'), $$('.sumary'), $('total') );

以下：
function init() {
if( location.pathname.search(/^\/(index\.html)?$/) >= 0 ) {
for(var i=0 ; i < document.getElementsByClassName('stealth').length ; i++) {
document.getElementsByClassName('stealth')[i].style['display']='none';
document.getElementsByClassName('detect')[i].innerHTML='<a title="展開隱藏區塊" onClick=" document.getElementsByClassName(\'stealth\')['+i+'].style[\'display\']=\'block\'; this.style.display=\'none\'; ">(繼續閱讀)</a>';
}
}
}
可以改成：
function init() {
if( location.pathname.search(/^\/(index\.html)?$/) >= 0 ) {
$$('stealth').each(function(element, index) { element.hide();
$$('.detect')[index].update('<a title="展開隱藏區塊" onClick=" $$(\'.stealth\')['+i+'].show(); $(this).hide(); ">(繼續閱讀)</a>');
}
}
}

反正...
document.getElementByClassName('blah') -> $$('.blah')
for 迴圈 ->.each()
element.innerHTML = 'blah' -> element.update('blah')
new Array(1, 2, 3) -> [1, 2, 3]
