Cordova Angularjs要求GPS [英] Cordova Angularjs ask for GPS

问题描述

我编程一个应用程序，我需要GPS。
如果GPS关闭，我怎么能要求用户打开GPS，如google地图？过了一段时间的googleing，我发现没有可比性...
我的其他问题是，为什么我得到使用位置？ - 2，当GPS关闭时？我想，如果GPS关闭，$ window.navigator.geolocation是false？

I program an app where I need GPS. If the GPS is off, how can I ask the user to turn on GPS, like google maps? After a while of googleing I found nothing compareable... My other question is, why I get "Use location? - 2", when the GPS is off? I thought, if the GPS is off, $window.navigator.geolocation is false?

controller.js

controller.js

if ($window.navigator && $window.navigator.geolocation) { 
    function success(pos) {
        $rootScope.position = { x: pos.coords.latitude, y: pos.coords.longitude };
    }
    function fail(error) {
        alert("Use location? - 2");
    }
     $window.navigator.geolocation.getCurrentPosition(success, fail, { maximumAge: 500000, enableHighAccuracy: true, timeout: 6000 });
} else {
    alert("Use location? - 1");
}

以帮助您获得，如果你的GPS是启用。然后您可以要求用户更改位置设置。其中一个是诊断插件 https://www.npmjs.com/package/cordova。 plugins.diagnostic 。我使用它。 （至少调用位置设置）。
