geolocation

问题 I'm retrieving results from mongo based on a geo query using the ruby driver. I'd like the results to be returned with their respective distances. That facility is available at the shell using geoNear command: db.runCommand( { geoNear : "places", near : [50,50], num : 10 } ); How do I do this via the ruby API? 回答1: where db is the connection to your db you can use #command : db.command({'geoNear' => "places", 'near'=>[50,50], 'num' => 10}) This has to be an OrderedHash in ruby 1.8, hashes are

问题 I have an ionic app that is trying to use geolocation exactly as shown in the docs. var posOptions = {timeout: 10000, enableHighAccuracy: true}; $cordovaGeolocation.getCurrentPosition(posOptions) .then(function (position) { // do something }, function(err) { console.log(err); // error }); But now it has stopped working and in the console gives me this warning. getCurrentPosition() and watchPosition() are deprecated on insecure origins, and support will be removed in the future.

问题 Since iOS 10 came out and I updated my iPhone 6 navigator.geolocation.getCurrentPosition() is not working. Address and port: 192.168.0.16:8100 Since geolocation API is considered as unsecured origin it would work only with SSL but can I do it in a Hybrid application where I don't know what will be the address on each phone?

问题 I am trying to get the location of the user with HTML5 geolocation . On Desktop it works great, but on all my mobile devices (Samsung note, Samsung galaxy S4 And Iphone 6) its not working and not showing the error object. this is my code: function showPosition(position) { var coor = position.coords.longitude+", "+position.coords.latitude; alert(coor); } function errorPosition(error) { alert(error); } function toggleGeolocation() { navigator.geolocation.watchPosition(showPosition,errorPosition

问题 I am trying to use HTML geolocation to get my position. Funny thing is, it was working brilliantly until some seemingly random point in the day when it just stopped working. Now all I get is the error callback with a message: Unknown error acquiring position This happened on the day I first started to develop the app. It is a web app built in Node/Express. The browser I am using is Firefox v53 64-bit. Location is allowed, and I have also tried a fix that I found online which involves going to

问题 I want to find out which country the user is currently in, in the event that a data connection is not available (so Geocoder doesn't work).

问题 I am using the PhoneGap API for geolocation. I have set the enableHighAccuracy Option to "true". Code 3, time out expired option keeps popping up, but only on some android devices and more than once while using the application. Please help me...
