如何使用Cordova检测GPS是否开启

Question

I am creating mobile app which uses geolocation plugin and I want show popup to enable GPS when GPS is turned off. How to detect whether GPS is on or off and how to show location setting to on GPS?

Answer 1

It can be done using the following Cordova Plugin: https://github.com/dpa99c/cordova-diagnostic-plugin

Add the plugin:

ionic plugin add cordova.plugins.diagnostic

Check for GPS whether it is enabled or not as below,

cordova.plugins.diagnostic.isLocationEnabled(successCallback, errorCallback);

If GPS is not enabled, Open Location settings as below,

cordova.plugins.diagnostic.switchToLocationSettings();

Complete code:

cordova.plugins.diagnostic.isLocationEnabled(successCallback, errorCallback);
function successCallback(res){
  console.log("Location is " + (res ? "Enabled" : "not Enabled"));
  !res ? cordova.plugins.diagnostic.switchToLocationSettings() : '';
}
function errorCallback(err){
  console.log("Error: "+JSON.stringify(err));
}
