Generally a web page has many hyperlinks to navigate to otherpages, by change some time unknowingly click on any other links...it will redirect to respective pages. then that current page data will be lost if we are in middle of something so that if we provide any message to the user about next occured event of the page.
in those cases generally in web. we promt an alert. same mechinasm we will implement using
$route--$routeChangeStart or $locationChangeStart events.
