我有網格視圖和以下代碼在javascript中添加新行。問題是，當我點擊按鈕添加新行時，它添加了行，但它也包含前一行數據，並且不保存到數據庫。它會產生錯誤「無效號碼」。使用Javascript添加行的網格
<script type='text/javascript' language='javascript'>
function AddNewRecord()
{
var grd = document.getElementById('GridView1');
var tbod=grd.rows[0].parentNode;
var newRow=grd.rows[grd.rows.length - 1].cloneNode(true);
tbod.appendChild(newRow);
return false;
}
</script>
<asp:Button ID="Button2" runat="server" Text="Add Row" OnClientClick="return AddNewRecord();"/>
我應該怎麼做，以便該行應該生成空白，也應該保存到數據庫。
我有這樣的代碼電網
