<!DOCTYPE html>
<html>
<body>
 
<p>点击按钮获取位置信息:</p>
 
<button onclick="getLocation()">点击这里</button>
 
<p id="demo"></p>
 
<script>
var x = document.getElementById("demo");
 
function getLocation() {
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(showPosition, showError);
  } else { 
    x.innerHTML = "Geolocation is not supported by this browser.";
  }
}
 
function showPosition(position) {
  x.innerHTML = "Latitude: " + position.coords.latitude + 
  "<br>Longitude: " + position.coords.longitude;
}
 
function showError(error) {
  switch(error.code) {
    case error.PERMISSION_DENIED:
      x.innerHTML = "User denied the request for Geolocation."
      break;
    case error.POSITION_UNAVAILABLE:
      x.innerHTML = "Location information is unavailable."
      break;
    case error.TIMEOUT:
      x.innerHTML = "The request to get user location timed out."
      break;
    case error.UNKNOWN_ERROR:
      x.innerHTML = "An unknown error occurred."
      break;
  }
}
</script>
 
</body>
</html>这段代码使用HTML5的Geolocation API来获取用户的当前位置。如果用户允许,则显示位置信息(纬度和经度),否则显示错误信息。这个例子简单明了地展示了如何在网页中集成地理位置定位功能。
