请教如何 用JS获得gridview里指定单元格里label的值

<asp:Panel ID="Panel1" runat="server" Height="208px" Width="498px" style="overflow-x:scroll;">
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" Width="480px" DataSourceID="FB_Product" OnRowDataBound="GridView1_RowDataBound">
<Columns>
<asp:TemplateField HeaderText="用于选择">
<ItemTemplate>
<input id="ck" type="checkbox" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="条形码">
<ItemTemplate>
<asp:Label ID="txm" runat="server" Text=' <%# Eval("strBarCode") %>'> </asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="拼音">
<ItemTemplate>
<%#Eval("strJaneCode")%>
</ItemTemplate>
</asp:TemplateField>
...
我要获得第一行条形码 单元格里txm Label的值 JS语句该怎么写啊？

Answer 1

function AA(o)//o是引发该方法的某行的控件，即调用该方法时AA(this)
{
while(o.tagName != "TR")
{
o = o.parentNode
}
r = o.rowIndex
document.getElementById("GridView").rows[r].cells[2].innerHTML
}
