使用流星框架处理地理定位

Question

How can I handle geolocation success and failure events within the meteor framework? More specifically, the call "navigator.geolocation.getCurrentPosition(showPosition);" says to call showPosition if there was success in getting the location. Whenever I define a generic javascript function (function showPosition(position) {}) I get a web socket error. So how do I call these functions within the meteor framework?

Answer 1

Check the module mdg:geolocation

meteor add mdg:geolocation

After use it in your code:

Geolocation.currentLocation()

Answer 2

This isn't a meteor feature specifically. It works with geolocation compatible browsers. Once you get the location you can send it or save it via Meteor.

Client side js: (make sure the collection exists on the server)

if (navigator.geolocation)
{
    navigator.geolocation.getCurrentPosition(showPosition);
}
   else{
       console.log("Geolocation is not supported by this browser.";
   }
}

function showPosition(position)
{
    Locations.insert({latitude: position.coords.latitude, 
                      longitude: position.coords.longitude});
}
