大佬教程收集整理的这篇文章主要介绍了android – phonegap：如何检查是否启用了gps，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我想显示一条警告说“请打开你的GPS”.

如何使用phonegap获取GPS状态？

我使用了以下代码,但如果关闭GPS,我不会收到任何警报消息.相反没有任何反应

<!DOCTYPE html>
  <html>
  <head>
   <title>Device Properties Example</title>

<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8">

// Wait for device API libraries to load
//
document.addEventListener("deviceready",onDeviceReady,falsE);

// device APIs are available
//
function onDeviceReady() {

   var test= navigator.geoLOCATIOn.getCurrentPosition(onsuccess,onError);

}

// onsuccess GeoLOCATIOn
//
function onsuccess(position) {
    var element = document.getElementById('geoLOCATIOn');
    element.innerHTML = 'Latitude: '           + position.coords.latitude              + '<br />' +
                        'Longitude: '          + position.coords.longitude             + '<br />' +
                        'Altitude: '           + position.coords.altitude              + '<br />' +
                        'Accuracy: '           + position.coords.accuracy              + '<br />' +
                        'Altitude Accuracy: '  + position.coords.altitudeAccuracy      + '<br />' +
                        'heading: '            + position.coords.heading               + '<br />' +
                        'Speed: '              + position.coords.speed                 + '<br />' +
                        'timestamp: '          + position.timestamp                    + '<br />';
}

// onError CallBACk receives a PositionError object
//
function onError(error) {
    alert('code: '    + error.code    + '\n' +
          'message: ' + error.message + '\n');
}

  <p id="geoLOCATIOn">   Finding geoLOCATIOn...</p>

解决方法

假设我们只讨论Android平台,正如 @Joerg正确地说,您可以使用 cordova.plugins.diagnostic检查是否使用 isGpsLocationEnabled()启用了GPS：

cordova.plugins.diagnostic.isGpsLOCATIOnEnabled(function(enabled){
    console.log("GPS LOCATIOn is " + (enabled ? "enabled" : "disabled"));
},function(error){
    console.error("The following error occurred: "+error);
});

如果结果是GPS已关闭,您可以将用户切换到位置设置页面以手动启用GPS：

cordova.plugins.diagnostic.switchToLOCATIOnSetTings();

或者,此外,您可以使用cordova-plugin-request-location-accuracy直接从应用程序内请求高精度定位模式(即GPS).这将显示原生确认对话框,如果用户同意,将自动启用GPS：

function onrequestsuccess(success){
    console.log("successfully requested accuracy: "+success.messagE);
}

function onrequestFailure(error){
    console.error("Accuracy request Failed: error code="+error.code+"; error message="+error.messagE);
    if(error.code !== cordova.plugins.LOCATIOnAccuracy.ERROR_user_DISAGREED){
        if(window.confirm("Failed to automatically set LOCATIOn Mode to 'High Accuracy'. Would you like to switch to the LOCATIOn SetTings page and do this manually?")){
            cordova.plugins.diagnostic.switchToLOCATIOnSetTings();
        }
    }
}

cordova.plugins.LOCATIOnAccuracy.request(onrequestsuccess,onrequestFailure,cordova.plugins.LOCATIOnAccuracy.requEST_PRIORITY_HIGH_ACCURACY);
