Hi xi chen, The notification widget shows a pop-up window on the screen to provide notifications. Use the following sample code to add notification in your web app:

text1

text2

Thanks, Vineet Tiwari

Hi xi chen, You have use focusin and focusout events to know whether your application is foreground or background. $("#page1").focusin(function (){ console.log("received focus In Event") ; }) $("#page1").focusout(function (){ console.log("received focus Out Event") ; })
