this above code working in chrome , firefox , mobile browser also, not working wepapp after build using phonegap. appreciated.

any geolocation example rendering location on map can helpful.

i ran exact same problem , found issue options passed in. if @ current example on phonegap.com getcurrent location: http://docs.phonegap.com/en/edge/cordova_geolocation_geolocation.md.html#geolocation

you'll notice no options passed in, it's simply: navigator.geolocation.getcurrentposition(onsuccess, onerror);

i deleted options , map popped right up. have not looked deeper since, cannot tell cause, please try deleting options , see if works.
