Witam.
Napisałem dzisiaj taki formularz z załączonym skryptem JS. Całość działa swietnie i wogóle... Ale jest całość jest troche duża co przy połączeniu z php i dynamicznym generowaniu dużych ilosci wierszy formularza może znacznie zmulić serwer i przeglądarke klienta. Czy byłby ktoś w stanie to jakos zminimalizować?? Bo ja próbuje i co zmienie jakąś nazwe/id/klase itp to wszystko sie wali (IMG:

(całość ma przypominać w działaniu panel PhpMyAdmin)
Oto kod:

var exp= new RegExp("^(.* )?"+cn+"( .*)?$", "g");

if (exp.test(els[i].className)){
arr.push(els[i]);
}
}
return arr;
}
function select_all(obj_check, cn_check, cn_uncheck, num_rows, style) {
var checkboxes = getElementsByClassName(cn_check);
var un_checkboxes = getElementsByClassName(cn_uncheck);
for (i = 0; i < checkboxes.length; i++) {
if (obj_check.checked == true) {
checkboxes[i].checked = true;
for (x = 0; x < un_checkboxes.length; x++) {
un_checkboxes[x].checked = false;
