str=str.substring(0,str.length-16);
str+= ' <tr> <td> <input type= "text " name= "text '+i+ ' " value= "text '+i+ ' " size= "21 "> </td> </tr> </tbody> </table> ';
document.all.mytable.outerHTML=str;

<form>
<table id=mytable>
<tr>
<td>
<input type= "text " name= "text1 " size= "21 ">
</td>
</tr>
</table>
<input type=button value= "增加 " onclick=addrow()>
<input type=button value= "累计 " onclick=sum()>
<input type= "text " name= "sumtext " value= " " size= "21 ">
</form>
</body>
</html>

想先实现,把文本框里面的值加到文本框sumtext中.
要是用vbscript来写,把他们的值写到数据库里,那么javascript里定义的变量i怎么用到.
