Single form submission script and AJAX...

[stuart]

Hi,

I am in the process of adding ajax to a large application - but due to a
script on the master page form tag the form disables itself after the first
post.

Is there any way to disable this script when an AJAX event is fired, but
allow it to run when a PostBack event fires?

<form id="aspnetForm" runat="server" onSubmit="if (this.submitted) return
false; this.submitted = true; return true">

Thanks in advance,

Stu
