send data from asp.net code behind to a javascript function

Question

Hello i have a aspx page and have this code on it:

<asp:Button ID="ButtonOk" runat="server" Text="Ok" OnClick="ButtonOk_Click" />

<script type="text/javascript">
    function fnClickOK(sender, e)
     {
        __doPostBack(sender, e);
     }
</script>

and on my code behind i have this code:

ButtonOk.OnClientClick = String.Format("fnClickOK('{0}','{1}')", ButtonOk.UniqueID, "");


protected void ButtonOk_Click(object sender, EventArgs e)
{

}

now i have a class (class someclass = new closs()) that is been Created in the code behind and i want to use it in the ButtonOk_Click function.

so I could do somthing like this:

protected void ButtonOk_Click(object sender, EventArgs e)
{
   string name = someclass.getname;
}

so how can i send data from my codebehind to my javascript function?

thanks.

I've found that the easiest way to send data back and forth between client and codebehind is to use jquery ajax functions and page methods.

Here's a good getting started article :
