Стоит задача передавать содержимое одного селекта в другой
например как в этом коде
| Код |
<html>
<head>
<title>Multy Select</title>
<script type="text/javascript">
function replacer(select1, select2, bool) {
var element;
if(bool) {
while(element = select1.firstChild)
select2.appendChild(select1.removeChild(element));
}
else {
for(var i = 0; element = select1.options[i]; i++) {
if(element.selected) {
select2.appendChild(element);
element.selected = bool;
}
}
}
}
function mover(o, bool) {
var e = o.options, i = o.selectedIndex, n = (bool) ? i - 1 : i + 1;
(i > -1 && n >= 0 && n < o.length) ? (o.insertBefore(o.removeChild(e[i]),
e[n]), o.selectedIndex = n) : '';
}
</script>
</head>
<body>

только есть проблема, когда в левом селекте выделяешь строки или Ctrl'ом или Shift'ом
то в правый селект передается максимум 2 значения
как с этим можно побороться ?? |
