Estoy probando para saber si mi ubicación actual está dentro del radio de ubicación (300 m). si es sí devuelve verdadero. de lo contrario devolver falso

por favor encuentre a continuación el código que está usando actualmente

 <body> <button onclick="getLocation()">Try It</button> <p id="demo"></p> <script> //below returant location var resturantLat = 47.55522178620101; var resturantLon = -122.34152897937625; var radius = 300 //show my current location in page var myLocation = document.getElementById("demo"); //get my current location function getLocation() { if (navigator.geolocation) { navigator.geolocation.getCurrentPosition(showPosition); } else { myLocation.innerHTML = "Geolocation is not supported by this browser."; } } function showPosition(position) { myLocation.innerHTML = "Latitude: " + position.coords.latitude + "<br>Longitude: " + position.coords.longitude; } var myLocationLat = position.coords.latitude; var myLocationLon = position.coords.longitude; /* if (my location inside radius){return true} else { return false} */ </script> </body>
