如何在IONIC FRAMEWORK中启用或不启用GPS服务 [英] How to check GPS service is enabled or not in IONIC FRAMEWORK

问题描述

我正在开发一个应用程序，它具有跟踪用户位置的功能，因为我使用了Cordova Geolocation插件，但在此之前必须检查GPS是否启用。

I am developing an application which has a facility to track user location for that I used Cordova Geolocation plugin but, before that have to check GPS is enable or not.

推荐答案

在Cordova Geolocation插件中有以下方法：

In the Cordova Geolocation plugin there is the method:

navigator.geolocation.getCurrentPosition(geolocationSuccess,
                                     [geolocationError],
                                     [geolocationOptions]);

这就是你所需要的。如果禁用了地理定位，则会调用 geolocationError 函数。 文档说在Android上你需要指定一个超时在 geolocationOptions 中，以便调用 geolocationError 函数。所以你必须这样做：

That is all you need. If geolocation is disabled, the geolocationError function is called. The docs say that on android you need to specify a timeout in the geolocationOptions in order to make the geolocationError function be called. So you would have to do it like so:

navigator.geolocation.getCurrentPosition(geolocationSuccess,
                                     [geolocationError],
                                     {timeout:3000});

在未收到后调用 geolocationError 函数3秒后地理定位（=地理位置关闭）。

To call the geolocationError function after not receiving a geolocation (= geolocation turned off) after 3 seconds.
