Is there a way to determine if location services using JavaScript are enabled on my mobile device?

I am currently using Modernizr to determine if geolocation is supported for a specific device. However, I want to show a more specific error message if geolocation is supported, but the user has disabled location services for his device.

I receive complaints that geolocation does not work on supported browsers, when in fact it is just that the user did not enable them.

I know there are ways to detect this using my own mobile code, but is there a way to do this using JavaScript? Does Modernizr support this?

Is your error callback being executed? If you don’t have one, try adding it. If it never fires, you can set a timeout in your function so that if it does not receive permission for a certain period of time, to display a notification.

Since errorCallback never fails if geo is disabled, create a wrapper around the function that will create the setting for another function. If any of the api callbacks are triggered, then remove the setting before it starts working.

var timeOutId; function disabledGeoHandler(){...} function show_map() { clearTimeout(timOutId); ... } function show_map_error() { clearTimeout(timOutId); ... } function lookup_location() { timeOutId = setTimeout(disabledGeoHandler, 1000); navigator.geolocation.getCurrentPosition(show_map, show_map_error); }

In fact, you can just use geo.js
