javascript - 定位用户 javascript 返回默认地址

Question

我需要使用 javascript 高精度地定位我的用户。

目前我正在使用这个库 https://github.com/onury/geolocator

有以下选项

var options = {
    enableHighAccuracy: true,
    timeout: 15000,
    maximumWait: 15000,     // max wait time for desired accuracy
    maximumAge: 0,          // disable cache
    desiredAccuracy: 30,    // meters
    fallbackToIP: false,    // fallback to IP if Geolocation fails or rejected
};

它有点慢，但大部分时间都运行良好。

但我时不时遇到地理定位问题，我真的不明白为什么，但输出是:

{
    "latitude": 40.712742950000006,
    "longitude": -74.00595024412516,
    "formattedAddress": "New York City Hall, 260, Broadway, Civic Center, Manhattan Community Board 1, Manhattan, New York County, New York, 10000, United States of America",
    "country": "United States of America",
    "city": "Manhattan Community Board 1",
    "state": "New York",
    "zipcode": "10000",
    "streetName": "Broadway",
    "streetNumber": "260",
    "countryCode": "US",
    "neighbourhood": "",
    "provider": "openstreetmap",
}

似乎是默认位置，但脚本应该使用浏览器位置功能。<​​/p>

所有用户都在移动设备上执行脚本

将超时选项设置为 Infinity 以避免在位置不可用(尚未)时返回。

HTML5 position timeout setting in milliseconds. Setting this to Infinity means that Geolocator won't return until the position is available.
