javascript - 如何通过一次点击链接连续获取位置

Question

我正在尝试通过 URL 访问获取移动用户位置。使用 PHP $_SERVER 变量我可以获得 ipv4/ipv6 地址，但结果不太准确。

with the one click of user javascript can send a client location. but it's asks for the user permission, it's fine. but after the one click, expecting to get a location continuously, even the browser is not active

您可以在起始页面的 PWA 中调用以下代码。这样，每次用户通过您提供的链接打开它时，应用程序都会获取她/他的位置:

function getLocation() {

  // Check if the current device support geoLocation
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(pos) {
      console.log("Latitude: " + pos.coords.latitude +
        "Longitude: " + pos.coords.longitude);
    });
  } else {
  // Geolocation is not supported by the
  }
}
