JS

document.addEventListener("deviceready", onDeviceReady, false);

var watchID = null;

// Cordova is ready
//
function onDeviceReady() {
// Throw an error if no update is received every 30 seconds
var options = { timeout: 30000 };
watchID = navigator.geolocation.watchPosition(onSuccess, onError, options);
}

// onSuccess Geolocation
//
function onSuccess(position) {
var element = document.getElementById('geolocation');
element.innerHTML = 'Latitude: '  + position.coords.latitude      + '<br />' +
                    'Longitude: ' + position.coords.longitude     + '<br />' +
                    '<hr />'      + element.innerHTML;
}

// onError Callback receives a PositionError object
//
function onError(error) {
alert('code: '    + error.code    + '\n' +

试试这个选项：

var options = { timeout: 30000, enableHighAccuracy: true };
