javascript - Use Browser to get GPS-Data and show pop-up and vibrate/play sound in Android -

i programme website using javascript. website has able contantly checking gps-chip of android device.

when specific coordinates match (coordinates given remote-server , coordinates given gps-chip), user should notification sound or vibration , pop-up-window farther information. like, when device passes coffeeshop, user alerted, there coffee in area.

it has website, not app.

is such thing possible?
