javascriptを使用して、チェックボックスの選択内容をクッキーに保存することができます。正しい方向に進むためのサンプルコードがあります。
var aa_checkbox;
function init_checkbox(){
//setup blank cb cookie
if(!Cookie.read('cb')){
Cookie.write('cb', JSON.encode({}));
}
//setup "associative array" to match what is currently in the cookie
aa_checkbox = JSON.decode(Cookie.read('cb'));
//set up each checkbox with class="remember_cb"
$$('input.remember_cb').each(function(el){
//mark checked if it is in the cookie
if(aa_checkbox[el.name]){
el.checked = 'checked'
}
//setup onclick event to put checkbox status in the
el.addEvent('click', function(){
if(el.checked){
aa_checkbox[el.name] = 1;
}else{
delete(aa_checkbox[el.name]);
}
})
})
//save aa_checkbox back into cookie upon leaving a page
window.onbeforeunload = function(){Cookie.write('cb', JSON.encode(aa_checkbox));};
setup_form();
return true;
}
function setup_form(){
//set up form so that it adds the inputs upon submit.
$$('form.remember_cb_form').each(function(form){
form.addEvent('submit', function(ev){
//clean up previously inserted inputs
var aa_hidden_insert = $$('input.hidden_insert');
$each(aa_hidden_insert, function(el){
el.parentNode.removeChild(el);
})
var el_form = this;
//insert hidden elements representing the values stored in aa_checkbox
$each(aa_checkbox, function(i_value, s_name){
if(i_value){
var el_input = document.createElement('input');
el_input.type = 'hidden';
el_input.value = i_value;
el_input.name = s_name;
el_input.setAttribute('class', 'hidden_insert');
el_form.appendChild(el_input);
}
});
});
});
}
window.addEvent('domready', init_checkbox);
