select列表各项上移和下移的js代码，可以手功排序，以前我们都见到过的，从事web编程的朋友经常会用得到。 [br][code]


<script>
function move(index,to) {
var list = document.form.list;
var total = list.options.length-1;
if (index == -1) return false;
if (to == +1 && index == total) return false;
if (to == -1 && index == 0) return false;
var items = new Array;
var values = new Array;
for (i = total; i >= 0; i--) {
items[i] = list.options[i].text;
values[i] = list.options[i].value;
}
for (i = total; i >= 0; i--) {
if (index == i) {
list.options[i + to] = new Option(items[i],values[i + to], 0, 1);
list.options[i] = new Option(items[i + to], values[i]);
i--;
}
else {
list.options[i] = new Option(items[i], values[i]);
}
}
list.focus();
}
function submitForm() {
var list = document.form.list;
var theList = "?";
for (i = 0; i <= list.options.length-1; i++) {
theList += "list" + list.options[i].value + "=" + list.options[i].text;
if (i != list.options.length-1) theList += "&";
}
location.href = document.form.action + theList;
}
</script>
