ios – Phonegap,Cordova watchposition火力每1秒成功一次

{ maximumAge: 3000,timeout: 5000,enableHighAccuracy: true }

我目前正在使用带有seTinterval的getCurrentPosition解决此问题.我不确定后果可能是什么,但这似乎给了我最大的控制权,似乎是跨平台最一致的方法.

// call this once
setupWatch(3000);

// sets up thE interval at the specified frequency
function setupWatch(freq) {
    // global var here so it can be cleared on logout (or whenever).
    activeWatch = seTinterval(watchLOCATIOn,freq);
}

// this is what gets called on thE interval.
function watchLOCATIOn() {
    var gcp = navigator.geoLOCATIOn.getCurrentPosition(
            updateUserLoc,onLOCATIOnError,{
                enableHighAccuracy: true
            });


    // console.log(gcp);

}

// do something with the results

function updateUserLoc(position) {


var LOCATIOn = {
    lat : position.coords.latitude,lng : position.coords.longitude
};

console.log(LOCATIOn.lat);
console.log(LOCATIOn.lng);
}

// stop watching

function logout() {
    clearInterval(activeWatch);
}
