Question

我有一个gridview，在这些列中总共有几列，其中一个是复选框，你需要做的是获取最后一列的值并将其显示（如果有几个添加它们）到网格中你用复选框选择试试甚至CheckedChanged（低音代码），这个代码下面只有我0而不是歌曲或总和，我被告知我可以用java scribt但我不知道该怎么做

代码：

    Dim Total As Decimal
    For Each row As GridViewRow In Gvcobranzas.Rows
        Dim check As CheckBox = DirectCast(row.FindControl("CheckBox1"), CheckBox)
        If check.Checked = True Then
            Dim x As Decimal = 0
            If Decimal.TryParse(row.Cells(2).Text, x) Then
                Total += CDec(row.Cells(2).Text)

            End If
        End If
    Next
    TxtMonto.Text = Total

                         //and to hold the reference to the current checkbox control
                         var totalPrice = 0, ctlPrice;
                         //iterate through all the rows of the gridview
                         $('.Gvcobranzas tr').each(function() {
                             //if the checkbox in that rows is checked, add price to our total proce
                             if ($(this).find('input:checkbox').attr("checked")) {
                                 ctlPrice = $(this).find('[id$= Label3]');
                                 //since it is a currency column, we need to remove the $ sign and then convert it
                                 //to a number before adding it to the total
                                 totalPrice += parseFloat(ctlPrice.text().replace(/[^\d\.]/g, ''));
                             }
                         });
                         //finally set the total price (rounded to 2 decimals) to the total paragraph control.
                         $('.sum').text("$ " + totalPrice.toFixed(2));
                     });
                 });
