Hi Bharani,
the return value is sent to nowhere. Or if it is, I don’t know. I’m not a javascript expert, just stumbled over this solution on the web and wrote it down here. Sorry, can’t help you any further with that.

#Hi Bharani,

#I don’t think you can find out the return value. Showing the popup message is the last thing that happens in the onbeforeunload event/method, and after that, #javascript is not running any more, so you can’t do anything in your script to react to the user’s input. I’m sorry. You could do a workaround by storing the #information that the user tried to close the window BEFORE showing the message, like this:

ok but the return value is sent to where? i need that one so if we find means we can handle the allthings of browser is possible means we are done.

Hi Bharani,

I don’t think you can find out the return value. Showing the popup message is the last thing that happens in the onbeforeunload event/method, and after that, javascript is not running any more, so you can’t do anything in your script to react to the user’s input. I’m sorry. You could do a workaround by storing the information that the user tried to close the window BEFORE showing the message, like this:




To use: 
1. click on the test link, see what happens.

2. try to close the window (browser (x)) - then select "stay on page"

3. click on the test link again - see that the message changed. 
Some test link

Please note that you can only evaluate the result if the user performs some action on your page, such as clicking on the test link. You would need to add the checkClosing() call to all your links and buttons and could even add it to the onbeforeunload function itself. not very elegant but the best I can do.

Hope this helps!

well, *I* do answer them, if you, dear Bharani, tell me what the problem is? Is there any way I can reproduce it in my own browser/webserver?

Hi Ayusman, sorry for the delay in replying to your last comment. I copied your code into a html file and opened it in my browser. It works as expected. I added some code: onclick="needToConfirm=false" to the google link, and then it deactivates the popup message as expected. If you right-click the link and say "open in new window", it does set the needToConfirm to false, too (similar effect when you add target="blank" to the link which opens the link in a new window) , but the main window is NOT relaoded and the needToConfirm remains false, and when you then refresh or close the main window, the warning message is not shown. That's a problem indeed, for which I have no solution. Perhaps there's some javascript action which can be executed AFTER a link was clicked, then we could use that to set needToConfirm="true" again?

Hi Kamatchi,
thanks for your comment. As far as I know, it’s not possible to distinguish between refresh and close events. But I’m not really an expert on this… I just copied the code from somewhere else.

hello

The above script is working fine while closing browser, but if i press refresh button it alerts the pop up message. I need the pop up only at the time of closing the browser not refresh or navigation through the pages.

Thanks in advance.
