定位失败 errorcode：7 errormessage：requestJsApis() not invoked
代码沿用demo里的，没使用dd.config，普通弹窗之类的api 成功。

dd.ready(function(){
            dd.device.geolocation.get({
                targetAccuracy : 12,
                onSuccess : function(result) {
                    /*
                    {
                        longitude : Number,
                        latitude : Number,
                        accuracy : Number,
                        isWifiEnabled : Boolean,
                        isGpsEnabled : Boolean,
                        isFromMock : Boolean,
                        provider : wifi|lbs|gps,
                        accuracy : Number,
                        isMobileEnabled : Boolean,
                        errorMessage : String,
                        errorCode : Number
                    }
                    */
                   alert(result);
                },
                onFail : function(err) {
                    alert(JSON.stringify(err));
                }
            });
        });
        dd.error(function(error){
            alart(error);
        });
