问题
All I've been able to find is how to specify the sensor parameter:
http://code.google.com/apis/maps/documentation/v3/#SpecifyingSensor
But nowhere does it say how to actually USE it. Isn't the whole point to be able to get the user's current lat/long coordinates through the device GPS, or am I mistaken?
回答1:
That sensor parameter is only there to indicate to Google that you are using a GPS sensor to determine the user's location.
Unless using the W3C Geolocation API in browsers that support it, it remains your responsibility to get the latitude and longitude from your GPS device to the user's browser.
