How can I set my latitude and longitude for debugging the Geolocation API with Google Chrome?

Question

For my development system I'd like to be able to set the Geolocation (Lat, Long) in Chrome so that when I'm doing the testing the browser thinks I'm at location X when I really might be at location Y.

Does anyone know how to force Google Chrome to use a Lat and Long that I provide as the location?

Answer 1

If you're talking about the Geolocation API, you can override the function:

navigator.geolocation.getCurrentPosition = function(success, failure) { 
    success({ coords: { 
        latitude: 30, 
        longitude: -105,

    }, timestamp: Date.now() }); 
} 

So when a library calls into the navigator.geolocation.getCurrentPosition function the coordinates you specify will be returned.

In Chrome today (version 42), open Developer Tools, click the "Toggle Device Icon", then in the "Emulation" drawer, chose "Sensors". There, you can Emulate geolocation coordinates and even "Emulate position unknown".
