How to determine the user's coordinates without requiring confirmation?

Question

Google Maps

All good.
At the moment I use this method to get the current coordinates
example:

window.COORDS = [];
        window.COORDS.push(78.42813734634228);
        window.COORDS.push(31.775801986455917);
navigator.geolocation.getCurrentPosition(function(position){
            window.COORDS[0] = position.coords.latitude;
            window.COORDS[1] = position.coords.longitude;
            console.log(position);
        },function(){

        });

Then I substitute the coordinates in Google maps for the position of the route.
The disadvantage of this method is that the user must give approval to receive his coordinates.
Question.
Can I somehow find out the user's coordinates without his approval?
