Question

appMobi watchPosition和getCurrentPosition失败，我的小GPS图标出现并继续，但是从appmobi网站复制和粘贴他们的确切示例，我应该至少得到一个警报，如果不是那么在控制台中出现错误我没有得到的调试器。

var options = {timeout: 10000, maximumAge: 11000, enableHighAccuracy: true };
//This function is called on every iteration of the watch Position command that fails
var fail = function(){
  alert("Geolocation failed. \nPlease enable GPS in Settings.");
};

//This function is called on every iteration of the watchPosition command that is a success
var suc = function(p){
  alert("Moved To: Latitude:" + p.coords.latitude + "Longitude: " + p.coords.longitude;
};

//This command starts watching the geolocation
var geolocationWatchTimer = AppMobi.geolocation.watchPosition(suc,fail,options);

//Call the stopGeolocation function to stop the geolocation watch
var stopGeolocation = function(){
        AppMobi.geolocation.clearWatch(geolocationWatchTimer);
}

......

更新

好的，注意到即使在那里使用示例代码也被破坏了。缺少a）和a;所以有了这些，我现在得到Uncaught TypeError: Cannot call method 'watchPosition' of undefined

好的， 再次更新

修复了最后一个问题，但是这一个让我感到困惑，似乎它现在运行了2次才停止，我需要它才能运行一次。我怎么能得到它？

Answer 1

放一个标志只运行一次。：

    ...lat=0;
var suc = function(p){
    if ((p.coords.latitude != undefined)&&(lat==0))
    {
            console.log(p.coords.latitude);
            lat=p.coords.latitude;
