如何去单元格的行号？？？

curRow = event.srcElement.parentElement.rowIndex;
var_filename = document.all.store_content.rows[curRow].cells[0].innerText;
curRow的值增加2??
curRow+2即可

to net_lover(孟子E章):
至少这样不可以：var_filename = document.all.store_content.rows[curRow+2].cells[0].innerText;
我已经试过啦，所以来问的。
加个转换
parseInt(curRow)+parseInt(2)
curRow = event.srcElement.parentElement.rowIndex;
这句话应该有问题。
event.srcElement未必是td，你得向上遍历
<body>
<script language="javascript">
function getFileName()
{
  var var_filename;
  curRow = event.srcElement
  while(curRow.tagName!="TR")
  curRow=curRow.parentElement
  if(curRow.tagName!="TR") return

  curRow=curRow.rowIndex;
  var_filename = document.all.store_content.rows[curRow].cells[0].innerText;
  alert(var_filename);
  if(document.all.store_content.rows[curRow+2])
  {
  var_filename = document.all.store_content.rows[curRow+2].cells[0].innerText;
  alert(var_filename);
  }
}
</script>
<table id=store_content border=0 onclick="getFileName()">
<tr>
<td>1</td><td>1</td><td>aaa</td>
</tr>
<tr>
<td>2</td><td>aaa</td><td>aaa</td>
</tr>
<tr>
<td>3</td><td>aaa</td><td>aaa</td>
</tr>
<tr>
<td>4</td><td>aaa</td><td>aaa</td>
</tr>
</table>
