    <Script language="JavaScript">
    //从from_list中的选项转移到to_list
    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

    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--)
    }
    }
    }
