$cordovaGeolocation is the Ngcordova plug-in that can get the current location, applied to it in the project, and explained here:

1, first need to download this plugin, the command is:

Cordova Plugin Add cordova-plugin-geolocation

　　

2, in the JS code as follows, this code is written in the corresponding controller and rely on ' $cordovaGeolocation ', remember in app.js rely on ' Ngcordova ', this is Ngcordova official website controller inside the code,:

Module.controller (' Geoctrl ', function ($cordovaGeolocation) {  var posoptions = {timeout:10000, enablehighaccuracy : false};  $cordovaGeolocation    . GetCurrentPosition (posoptions)    . Then (function (position) {      var lat  = Position.coords.latitude      var long = position.coords.longitude    }, function (err) {      //Error    });});

　　

3, in the project, I need real-time monitoring of the geographical location, so the use of angularjs inside the $broadcast, $on; $broadcast can monitor the change in value, and $on is a change in the value of the monitoring, can trigger to it, With the plug-in for getting the location mentioned above, you can always monitor the location changes, the code is as follows:

Module.controller (' Geoctrl ', function ($cordovaGeolocation) {  function getcurrentposition () {var posoptions = { timeout:10000, enablehighaccuracy:false};  $cordovaGeolocation    . GetCurrentPosition (posoptions)    . Then (function (position) {     $rootScope. $ Broadcast (' selflocation:update ', position);      var lat  = Position.coords.latitude      var long = position.coords.longitude    }, function (err) {      //Error    });});

　　

In other controllers that need to get position, add $on:

$scope. $on (' Selflocation:update ', function (_, location) {  //constantly updated value  $scope. currentposition = {    Latitude:location.latitude,    longitude:location.longitude  };});

Just call the GetCurrentPosition () function, and you can always monitor the change in location data.
