修正代码为：（错误原因有三条）
function transform(from_list,to_list){
for(var i=0;i<from_list.options.length;i++){
if(from_list.options[i].selected){
var str=from_list.options[i].text
to_list.options[to_list.options.length++]=new Option(str,str)
from_list.remove(i--)
}
}
}
function transform(from_list,to_list){
for(var i=0;i<from_list.options.length;i++){
if(from_list.options[i].selected){
var str=from_list.options[i].text
to_list.options[to_list.options.length++]=new Option(str,str)
from_list.remove(i--)
}
}
}

<Script language="JavaScript">

function transform(from_list,to_list){
var from_length=from_list.options.length
var to_length=to_list.options.length
for(var i=0;i<from_length;i++){
if(from_list.options[i].selected){
var str=from_list.options[i].text
to_list.options[to_length++]=new Option(str,str)
from_list.options[i--]=null
}
}
}
</Script>
