一个select表单移处数据的效果，非常好用。

<table>
<tr><td>
    <select id="select_left" size="10" multiple="multiple" style="width:150px">
    <option value="23562356856" selected="selected">张老大 23562356856</option>
    <option value="23623568562">刘老四 23623568562</option>
    <option value="23635254345">令胡冲 23623568562</option>
    <option value="13714715608">杨庆荣 13714715608</option>
    </select>
</td>
<td>
    <input type="button" value=">>" onclick="allToRight();"><br>
    <input type="button" value=">" onclick="selectedToRight();"><br>
    <input type="button" value="<<" onclick="allToLeft();"><br>
    <input type="button" value="<" onclick="selectedToLeft();"><br>
