onbeforeunload event behaves weirdly

RJN

Hi

I have an onbeforeunload event where in I call a server side script to
release some locks on the databse.

function releaseLock()
{
__doPostBack('b tnUnlock','');
}
<body onbeforeunload= "releaseLock(); >

btnUnlock is a server side html button. I found that in a few occasions
I found that the lock was not released when the page was closed.(clicked
on the top right X). I put an alert inside and the message comes up. Any
idea why this inconsistent behaviour?

Regards

this would prevent the user from ever closing it... it's by design.

Wait till image is loaded from "onbeforeunload" handler?

by: Robert Oschler | last post by:

I have a web page where I want to make sure that an image HTTP request is successfully made before the page unloads. The request is made by setting the image element's SRC property to the desired URL. When I put the SRC property change in either an "onbeforeunload" or "onunload" event handler, the HTTP request is not received by our server as much as 75% of the time. I thought of setting a flag using an "onload" handler for the image...

onbeforeunload doesn't work in Safari

by: jennyw | last post by:

Hi, I'd like to use onbeforeunload to submit a form before leaving a page. This works in Firefox and IE. Safari, however, blithely ignores this. Does anyone know of a workaround for Safari? Or another way to do the same thing in Safari? (that is, intercept a request to leave the page). I tried Safari 2.02 on Tiger. Thanks!

Using the OnBeforeUnload JavaScript Event

by: Frinavale | last post by:

Introduction I've seen many questions asked about how to disable the browser's back button and in the past I've replied with "it's simply not possible". It's not a good idea to disable the back button anyways, if the user ventures away from your page then they wouldn't have this button at their disposal. The main reason people ask how to control or disable the back button is because they have a need to control sensitive (and/or) dynamic web...

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
