  • Please elaborate, because your question does not provide enough information. You could use Ajax or post back a form to the server, but maybe you don't really need to do this. Keep in mind that JavaScript runs in the browser and the code in the code-behind file runs on the server. – npclaudiu Nov 08 '11 at 13:03

The use of a hidden field will be your solution :

In javascript : 

function SetValue()
{
    $('#<%=Hidden1.ClientID%>').val() = "testing !!!!!";
}

And in html you need this : 

<input id="Hidden1" runat="server" type="hidden" value="" />

or this : 

<asp:HiddenField ID="Hidden1" runat="server" Value="" />

And then because you hiddenfield is runat server you can access it in the code behind at the next post back.

If you don't want to do a postback you may need to use a webMethod

  • At the runtime ID value may be change, therefore I think it will be safer to use class instead of id – huMpty duMpty Nov 08 '11 at 13:10
  • It's true or use this <%=Hidden1.ClientID%> – GregM Nov 08 '11 at 13:11
  • Input type values are passed as a part of Request.Form NameValueCollection. You can use the "name" property of the hidden input type for accessing the value from this collection.

In addition on using Hidden field, I always avoid using spaghetti code. You can do this in jQuery. using the $ selector, you will always get the correct ID of a server control.

<asp:HiddenField ID="Hidden1" runat="server" Value="" />
<style type="text/javascript">
    function SetValue()
    {
        $("input[id$='Hidden1']").val("Some Value");
    }
</style>
