Hi!
I want to get a textbox value from Html and Jquery and then store it in a variable in c#.
I am using this code but I dont know what next:

XML

<head runat="server">
    <title></title>
     <script type="text/javascript" src="../javascripts/jquery-1.8.js"></script>
     <script type="text/javascript">
        window.onload = function () {
            $('#randomText').hide();

         }
        $('#linkbutton').live("click", function (e) {
            event.preventDefault();
            $('#randomText').val(random());
            alert('Reference Code: ' + $('#randomText').val());
        });
        function random() {
            return Math.floor(Math.random()*10000000);
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <asp:LinkButton ID="linkbutton" runat="server">Click me!</asp:LinkButton>

    <asp:TextBox ID="randomText" runat="server"></asp:TextBox>
     </div>
    </form>
</body>
</html>

as u can see this code is generating a random number and set it into a textbox.then what I want is to get that textbox value and store it in a c# variable.Help fixing this...

Solution 1

you are preventing postback of button click

use this

<asp:LinkButton ID="linkbutton" runat="server" onclick="linkbutton_Click" OnClientClick="return generateRandom();" >Click me!</asp:LinkButton>

and javascript function

function generateRandom()
{

C#

$('#randomText').val(random());
            alert('Reference Code: ' + $('#randomText').val());

return true;

}

and on server side get value of textbox.

Thnks its works but last thing is there any way to prevent a duplicate random number.

its random,there is always a possibility,use guid generator or check whether random number exists or not
