呵呵，muxrwc的JS造诣已经相当高了，居然还如此谦虚，佩服~~
JK兄的代码很经典，偶就不献丑了，飘过...^_^
2楼给的这个代码应该可以解决你的问题了，大体看了一下，没有细看。<select id="s1" size="5" multiple="multiple">
    <option value="11111">11111</option>
    <option value="22222">22222</option>
    <option value="33333">33333</option>
    <option value="44444">44444</option>
    <option value="55555">55555</option>
</select><select id="s2" size="5" multiple="multiple">
</select><br /><br />
<input type="button" value="添加" onclick="AddOrRomove('add');" />
<input type="button" value="删除" onclick="AddOrRomove('remove');" /> <script language="javascript" type="text/javascript">
function AddOrRomove(action)
{
    var s1 = document.getElementById("s1");
    var s2 = document.getElementById("s2");
    var optionArray = new Array();

    if (action == "add") //添加
    {
        for (var i=0;i<s1.options.length;i++)
        {
            if (s1.options[i].selected == true)
            {optionArray.push(s1.options[i]);}
        }

        for (var j in optionArray)
        {
            optionArray[j].selected = false;
            s2.options.appendChild(optionArray[j]);
        }
    }
    else if (action == "remove") //删除

            {optionArray.push(s2.options[i]);}
        }
