detect if user clicked on add to home screen

Question

with javascript or jQuery, is there a way to detect if the user added my site to his home screen in mobile browsers?

i want to detect it at the second he hit on 'add to home screen'

Answer 1

You can try this

if(isMobile.any()) {
   alert("This is a Mobile Device");
}

And then

$("#btn-id").on('click',function(){
  //Write code to get msg
)};

Answer 2

Mmm this should be part of the browser's functionality and is not likely to be exposed to the js on a particular page.

So ... I think you cannot do in within the page.
