use geolocation api. obtain current location, can call getcurrentposition() method. initiates asynchronous request detect user's position, , queries positioning hardware up-to-date information.

when position determined, defined callback function executed. can optionally provide second callback function executed if error occurs. third, optional, parameter options object can set maximum age of position returned, time wait request, , if want high accuracy position.

this documentation , example might you.
