对不起，我缺乏知识，但我正在尝试从 javascript 打印出 html 代码中的 vars（如果有人可以清理 JS，那将是一个奖励）。我尝试添加 document.write 但从未奏效。基本上我需要街道和国家在地图下打印出来。

 <!DOCTYPE HTML>
<html>
<head>
<script src="http://maps.google.com/maps/api/js?sensor=false">
</script>
<script type="text/javascript">
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(function(position){
        var latitude = position.coords.latitude;
        var longitude = position.coords.longitude;
        var coords = new google.maps.LatLng(latitude, longitude);
        var mapOptions = {
            zoom: 15,
            center: coords,
            mapTypeControl: true,
            navigationControlOptions: {
                style: google.maps.NavigationControlStyle.SMALL
            },
            mapTypeId: google.maps.MapTypeId.ROADMAP
            };
            map = new google.maps.Map(
                document.getElementById("mapContainer"), mapOptions
                );
            var marker = new google.maps.Marker({
                    position: coords,
                    map: map,
                    title: "Your current location!"
            });

        });
    }else {
        alert("Geolocation API is not supported in your browser.");
    }
</script>

<script type="text/javascript"> 
  var geocoder;

  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(successFunction, errorFunction);
} 
//Get the latitude and the longitude;
function successFunction(position) {
    var lat = position.coords.latitude;
    var lng = position.coords.longitude;
    codeLatLng(lat, lng)

function errorFunction(){
    alert("Geocoder failed");

  function initialize() {
    geocoder = new google.maps.Geocoder();



  }

  function codeLatLng(lat, lng) {

    var latlng = new google.maps.LatLng(lat, lng);
    geocoder.geocode({'latLng': latlng}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
      console.log(results)
        if (results[1]) {
         //formatted address
         alert(results[0].formatted_address)
        //find country name
             for (var i=0; i<results[0].address_components.length; i++) {
            for (var b=0;b<results[0].address_components[i].types.length;b++) {

            //there are different types that might hold a city admin_area_lvl_1 usually does in come cases looking for sublocality type will be more appropriate
                if (results[0].address_components[i].types[b] == "administrative_area_level_1") {
                    //this is the object you are looking for
                    city= results[0].address_components[i];
                    break;
                }
            }
        }
        //city data
        alert(city.short_name + " " + city.long_name)


        } else {
          alert("No results found");
        }
      } else {
        alert("Geocoder failed due to: " + status);
      }
    });
  }

您可以使用以下构造代替 document.write

var x= document.getElementById("mapContainer");
x.innerHTML="your content goes here";
