May it would be good to have such functionality in web applications, but the application lifecycle and architecture of a Web applications is quite different from Native applications. I guess that's why we are not seeing similar alternatives. You may also check this post here:

May have to look for some workarounds.

Yes, you are right, its web app, I forgot. 'unload' event enough.
