Hi,
I want to call a web service when a user closes the browser window. On closing the browser window, I get the following error:
Microsoft JScript runtime error: 'service.SessionSpan' is null or not an object
I have attached the code for reference, please advise.
<HTML>
<HEAD>
<script lang="javascript">
function funcInit()
{
var iCallID = 0;
service.useService("http://localhost/UpdateSessionDetails/SessionSpan.asmx?WSDL", "update");
iCallID = service.SessionSpan.callService("UpdateSessionTabl e");
}
</script>
</HEAD>
<body MS_POSITIONING="GridLayout" onbeforeunload="funcInit()">
<div id="service" style="behavior:url(webservice.htc)"></div>
<form id="Form1" method="post" runat="server">
<asp:LinkButton ID="lbtnSummary" Runat="server">Download Summary.txt</asp:LinkButton>
</form>
</body>
</HTML>
javascript: null or not an object exception
