javascript and jquery to show values in lable instead of Textbox

Mar 01, 2012 03:32 AM|LINK

Hi

This is my aspx page

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" ShowFooter="true">
        <Columns>
            <asp:TemplateField HeaderText="Rate">
                <ItemTemplate>
                    <asp:TextBox ID="Rate" runat="server" CssClass="textSelector" />
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField HeaderText="Quantity">
                <ItemTemplate>
                    <asp:TextBox ID="Quantity" runat="server" CssClass="textSelector"  />
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField HeaderText="Amount">
                <ItemTemplate>
                    <asp:Label ID="Amount" runat="server"  />
                </ItemTemplate>
                <FooterTemplate>
                    <asp:Label ID="GrandTotalWithoutTax" runat="server"  /><br />
                    <asp:Label ID="TaxValue" runat="server"  /><br />
                    <asp:Label ID="GrandtotalWithTax" runat="server"  /><br />
                </FooterTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

how would be my javascript code if Amount will be displayed in label also Gradtotalwithouttax,taxvalue,grandtotalwithtax your javascript

<head runat="server">
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            $(".textSelector").keyup(function() {
                var row = $(this).closest("tr");
                var Rate = parseFloat(row.find("input[type=text][id*=Rate]").val());
                if (isNaN(Rate)) Rate = 0;
                var Quantity = parseFloat(row.find("input[type=text][id*=Quantity]").val());
                if (isNaN(Quantity)) Quantity = 0;
                row.find("input[type=text][id*=Amount]").val(Rate * Quantity);
                var total = calculateTotal();
                var taxValue = parseFloat($("input[type=text][id*=TaxValue]").val());
                if (isNaN(taxValue)) taxValue = 0;
                $("input[type=text][id*=GrandtotalWithTax]").val(total + taxValue);
            });
        });
        function calculateTotal() {
            var total = 0;
            $("input[type=text][id*=Amount]").each(function() {
                temp = parseFloat($(this).val());
                if (isNaN(temp)) temp = 0;
                total = total + temp;
            });
            $("input[type=text][id*=GrandTotalWithoutTax]").val(total);
            return total;
        }
    </script>
</head>

The above javascript works fine if my 3rd column Itemtemplate and footertemplate will be Textbox now insted of Textbox i want to show in Label, so how would be my javascript..

Hi Priya,

Instead of TextBox , if its Label then.

code:

$("span[id*=GrandtotalWithTax]").text("yourtext");

Because label generates span.

Please mark the post as "Answer" that helps you.

hai priya, when every .aspx page is rendering <asp:TextBox>, it will be converted in to <input type ="text" > like that ,but label is converted into span.

so you need write $("input[type=span][id*=GrandTotalWithoutTax]").val(total); instead of

$("input[type=text][id*=GrandTotalWithoutTax]").val(total);

Hi

In the client ,the label control is interpreted as span element,

Please have a try this, $("span#GrandtotalWithTax").val(total) in the javascript.

Hope it helps

just use span instead of text when you are using label in jQuery.

Label does not generate input element...but just span

so..instead of  this:

$("input[type=span][id*=AmountTotal]").val(total);

use:
$("span[id*=AmountTotal]").val(total);

Labels can be found using:

$("span[id*=idoflabel]").val(total);
