Detect Browser Close on Asp.net

Question

I want to do some functionality on log-out, if the user directly closed his browser then same functionality want to do, we can not do on page unload because there are more

Answer 1

Isn't this what Session_OnEnd in global.asax is for?

This event isn't triggered when the browser is closed.

Answer 2

You can have a button for the "logout" case.

Unfortunately, there is no reliable way to be notified if the user closes their browser. Other than client-side page unload, which you've said you don't want, about the only other option is periodic Ajax-based polling; both are ugly and notoriously unreliable.

In general, server-side timeouts are a better approach.

Answer 3

<script type="text/javascript">
var closing = true;
$(function () {
    $("a,input[type=submit]").click(function () { closing = false; });
    $(window).unload(function () {
        if (closing) {
            jQuery.ajax({ url: "http://localhost:49591/Account/LogOff", async: false });
        }
    });
});
</script>

Call the logout.aspx when window closes using javascript + jquery. Do whatever you want to do in the logout.aspx page load event.

The above snippet will have to be added in your master page's html.
