appMobi watchPosition和getCurrentPosition失败，我的小GPS图标出现并继续，但从appMobi站点复制和粘贴（以它们的确切示例为例），我至少应该得到一个警告，如果没有，那么调试器控制台中的错误，我也没有得到。

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，注意到即使使用这个例子，代码也有一定的漏洞。它缺少a）和a；所以有了这些，我现在得到了Uncaught TypeError: Cannot call method 'watchPosition' of undefined

好的，再次更新

修复了上一个问题，但这个问题让我很困惑，现在似乎它运行了2次是为了停止，我只需要它运行一次。我怎么能拿到？

只运行一次标志

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