I want to update DB when the user closes the browser. I am capturing it in windows.onbeforeunload in javascript . I want to call a function in server side when the when the on before unload event and update the DB.
I am using asp.net 2.0 Framework and don't have ajax installed in my system. So I scriptmanager is not recognized by asp.
Can I have any other way to call a server side function from javascript without using script manager or pagemethods. Please help!!!!
Use following code is asp.net client side :
<script>
function CallServerMethod() {
alert("<%= GetValue(" karthick ") %>");
}
</script>
then write code on asp.net button as OnClientClick="CallServerMethod();"
i.e
<asp:Button ID="Button1" runat="server" OnClientClick="CallServerMethod();" Text="Button" />
In code behind . i.e .cs page declare the function GetValue() as below
public String GetValue(string myval)
{
return myval;
}
as soon as you click then GetValue() you will see alert box.
I suppose you could try using the jQuery post method. You could even post to a different page and pass any arguments you need to do the DB update.
