揭帖这么快！汗！写了个小demo<table>
  <tbody>
    <tr>
      <th>2进制</th>
  <input type="text" id="txtNum"/>
      <td><input type="button" value="10转2" onclick="convert_digits_from('txtNum',2)"/></td>
    </tr>
    <tr>
      <th>3进制</th>
      <td><input type="button"  value="10转3" onclick="convert_digits_from('txtNum',3)"/></td>
    </tr>
    <tr>
      <th>4进制</th>
      <td><input type="button"  value="10转4" onclick="convert_digits_from('txtNum',4)"/></td>
    </tr>
    <tr>
      <th>5进制</th>
      <td><input type="button"  value="10转5" onclick="convert_digits_from('txtNum',5)"/></td>
    </tr>
   </tbody>
</table>
<script>
 var w=function(s){alert(s)}; 
var convert_digits_from=function(num,el)
{
var obj=document.getElementById(num).value;
//alert(obj);alert(el);
//alert(obj.toString(el));
  
w(parseInt(obj,10).toString(el));   
};
</script>
