I noticed on few sites, if the process is not finished and in between user wants to leave the page then the browser shows this warning.

Are you sure you want to leave this page?

Have you saved your files?

[Leave this page] [Stay on this page]


I saw this in the IE but crome also does the same job.


I have asp.net page which has log form which user needs to fill.
I also need to stop user by showing this same message when he tries leave the page without saving the changes first.

how can I do this?

That's about Javascript events.

I don't know how you best make use of this in ASP.NET, but since it's a client side event it has to be done in Javascript anyway. Do you use jQuery? ASP.NET MVC?

Then you can make use of the more specific jQuery event handling.

$(window).bind('beforeunload', function(){
		return 'Are you sure you want to leave without saving changes?';
	});

Open in new window


And like in the other example given, you can decide whether to show such a warning message by checking, if the user entered something into a form element, which should not get lost.

Return null, if you want to let the user leave without further notice.

Bye, Olaf.
