Sort();

HVorfor virker dette script ikke?


<script>
var sort_i,sort_isec;
function sortList() {
var obj = frmuser.userList;
var tmp = new Array();
for (sort_i = 0; sort_i < obj.length; sort_i++)
{
    tmp[sort_i] = obj.options[sort_i].text.toLowerCase();
    obj.options[sort_i] = null;
}
tmp.sort();

for(sort_isec = 0; sort_isec < sort_i; sort_isec++)
{
obj.options[obj.options.length] = new Option(tmp[sort_isec],sort_isec);
}
}
</script>

<input type="button" value="tryk" onclick="sortList();">
<form name="frmuser">
<select name="userList" size="10">
<option>Mads</option>
<option>sjov</option>
