Question

I select a textbox in a gridview row.
I know that a gridview is a html-table.
How can I find out whether the td where the textbox is in is the next to last td in the tr of the table with jQuery?

<asp:GridView runat="server">
<Columns>
    <asp:TemplateField HeaderText="Standardpreis">
        <ItemTemplate>
            <asp:TextBox runat="server" ID="valueTxt"></asp:TextBox>
        </ItemTemplate>
    </asp:TemplateField>            
</Columns>

Something like this in the event for the child element

var $that = $(this),
    $td = $that.closest('td'),
    trChildrenCount = $td.parent().children().length,
    tdBeforeLast = trChildrenCount - 1,
    tdIndex = $td.index() + 1; // get 1-based index

if (tdBeforeLast === tdIndex) {
    console.log('next to last td');
    // do stuff...
}
