但是我测试中为null：
if (google.loader.ClientLocation)
这是谷歌没有找到IP信息的行为。
我搜索了StackOverflow，有很多问题，但没有很好的答案。
我在网上搜了一下，看到这两个链接：

应该使用哪个导航器HTML地理位置。
Google API文档不再提及。
我想要确认Google google.loader.clientlocation是否仍然工作？
我的代码如下：
<html>
<head>
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
</head>
<body>
<script type="text/javascript">
function geoTest() {
if (google.loader.ClientLocation) {
var latitude = google.loader.ClientLocation.latitude;
var longitude = google.loader.ClientLocation.longitude;
var city = google.loader.ClientLocation.address.city;
var country = google.loader.ClientLocation.address.country;
var country_code = google.loader.ClientLocation.address.country_code;
var region = google.loader.ClientLocation.address.region;
var text = 'Your Location<br /><br />Latitude: ' + latitude + '<br />Longitude: ' + longitude + '<br />City: ' + city + '<br />Country: ' + country + '<br />Country Code: ' + country_code + '<br />Region: ' + region;
} else {
var text = 'Google was not able to detect your location';
}
document.write(text);
}
geoTest();
</script>
</body>
</html>
解决方法
这是我从这里得到的答案：

The geolocation functionality in the Loader hasn’t been retired,per se. We stopped documenting it several years ago and have recommended the HTML-based solutions due to their improved accuracy,but the functionality itself has not been removed from the Loader at this time. Thanks!
所以当找不到IP的位置时，google.loader.ClientLocation为null
