lat should always be between -90 to 90 and long should always be -180 to 180 "text/javascript" > function ValidateLatLng() { var lat = document.getElementById( "txtLat" ).value; var lng = document.getElementById( "txtLon" ).value; if (lat 90) { alert( "Latitude must be between -90 and 90 degrees inclusive." ); } else if (lng 180) { alert( "Longitude must be between -180 and 180 degrees inclusive." ); } else if (lat == "" || lng == "" ) { alert( "Enter a valid Latitude or Longitude!" ); } } for anonymous point finding out the correctness of a lat/long is neareset to impossible cause every point in the range could be considered as a right value , so no regular expression can test it completely yet function isValidLatitude($latitude){ if (preg_match( "/^-?([1-8]?[1-9]|[1-9]0)\.{1}\d{1,6}$/" , $latitude)) { return true ; } else { return false ; } } function isValidLongitude($longitude){ if (preg_match( "/^-?([1]?[1-7][1-9]|[1]?[1-8][0]|[1-9]?[0-9])\.{1}\d{1,6}$/" , $longitude)) { return true ; } else { return false ; } } // testng both at a time as function IsvalidLatLong(lat,long) { const regex = new RegExp(" /^-?([1]?[1-7][1-9]|[1]?[1-8][0]|[1-9]?[0-9])\.{1}\d{1,6}$/ "); return regex.test(lat) && regex.test(long); } This is what i have used in my application , so it should work for you.

Try this simple function function validateLatLng(lat, lng) { let pattern = new RegExp( '^-?([1-8]?[1-9]|[1-9]0)\.{1}\d{1,6}' ); return pattern.test(lat) && pattern.test(lng); } Let me know if this helps you. Regards Rijwan
