Hm, det må være noget med:
<html>
<head>
<script type="text/javascript">
var num = 5;
var num2id = new Array();
num2id[1] = 1;
num2id[2] = 2;
num2id[3] = 3;
num2id[4] = 4;
num2id[5] = 5;
var id2num = new Array();
id2num[1] = 1;
id2num[2] = 2;
id2num[3] = 3;
id2num[4] = 4;
id2num[5] = 5;
function updateSelect(s) {
var oldids = num2id.slice();
var id = s.id.substring(3);
var n = Number(s[s.selectedIndex].value);
var pn = Number(id2num[id]);
var sign = n > pn ? -1 : 1;
for (var i = n; sign*i < sign*pn; i+=sign) {
id2num[oldids[i]] = i+sign;
num2id[i+sign] = oldids[i];
document.getElementById("val"+oldids[i]).options[i-1+sign].selected = true;
}
num2id[n] = id;
id2num[id] = n;
}
</script>
<body>
<div>
Valg 1:
<select id="val1" name="val1" onchange="updateSelect(this)">
<option value="1" selected>1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
</div>
<div>
Valg 2:
<select id="val2" name="val2" onchange="updateSelect(this)">
<option value="1">1</option>
<option value="2" selected>2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
</div>
<div>
Valg 3:
<select id="val3" name="val3" onchange="updateSelect(this)">
<option value="1">1</option>
<option value="2">2</option>
<option value="3" selected>3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
</div>
<div>
Valg 4:
<select id="val4" name="val4" onchange="updateSelect(this)">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4" selected>4</option>
<option value="5">5</option>
</select>
</div>
<div>
Valg 5:
<select id="val5" name="val5" onchange="updateSelect(this)">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5" selected>5</option>
</select>
</div>
</body>
</html>
Virker det som forventet?
