The example in this article describes the method of using js html5 to obtain user geographical location information and display it on Google Maps. Share it with everyone for your reference. The specific implementation method is as follows:

<body>
<p id="demo">Click the button to get your position:</p>
<button onclick="getLocation()">Try It</button>
<div id="mapholder"></div>
<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)
 {
 var latlon=position.coords.latitude+","+position.coords.longitude;
 var img_url="http://maps.googleapis.com/maps/api/staticmap&#63;center="
 +latlon+"&zoom=14&size=400x300&sensor=false";
 document.getElementById("mapholder").innerHTML="<img src='"+img_url+"' />";
 }
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."
