MDN, the local operation does not print the geographical location, nor does it report an error. Why? Ask for instructions
at the beginning, the PC side has been returning a timeout. It may be because the PC side does not support it. After opening it with your mobile phone, you will be prompted: error.code 1 PERMISSION_DENIED

Mobile phone Google browser error: err.code 1, does not allow access to geographical location, how to solve?
where can I reopen the allow or how does js modify whether it is allowed?

    var options = {
      enableHighAccuracy: true,
      timeout: 5000,
      maximumAge: 0
    };
    
    function success(pos) {
      var crd = pos.coords;
    
      console.log("Your current position is:");
      console.log("Latitude : " + crd.latitude);
      console.log("Longitude: " + crd.longitude);
      console.log("More or less " + crd.accuracy + " meters.");
    };
    
    function error(err) {
      console.warn("ERROR(" + err.code + "): " + err.message);
};

navigator.geolocation.getCurrentPosition(success, error, options);
