我首先在bootstrap studio中创建了我的代码，它似乎可以正常工作，但是当我在MS Visual Studio中将其传输时，反向地理编码按钮（或者我应该说整个函数本身）不会返回任何内容。这是我的反向地理编码功能：
//Reverse Geocode
//once clicked
function ReverseGeocode() {
var lat = document.getElementById("latitude").value;
var lng = document.getElementById("longitude").value;
var latlng = new google.maps.LatLng(lat, lng);
var geocoder = new google.maps.Geocoder();
geocoder.geocode({ 'latLng': latlng }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[0]) {
document.getElementById('address').value=results[0].formatted_address;
}
}
//fragment address
var streetName;
var city;
var state;
var zip;
var country;
var placeId;
for(var j = 0; j < results[0].address_components.length; j++){
for(var k = 0; k < results[0].address_components[j].types.length; k++){
if (results[0].address_components[j].types[k] == "route"){
streetName = results[0].address_components[j].long_name;
document.getElementById('route').value = streetName;
}
else if (results[0].address_components[j].types[k] == "locality"){
city = results[0].address_components[j].long_name;
document.getElementById('city').value = city;
}
else if (results[0].address_components[j].types[k] == "administrative_area_level_2"){
state = results[0].address_components[j].long_name;
document.getElementById('administrative_area_level_2').value = state;
}
else if (results[0].address_components[j].types[k] == "postal_code"){
zip = results[0].address_components[j].long_name;
document.getElementById('postal_code').value = zip;
}
else if (results[0].address_components[j].types[k] == "country"){
country = results[0].address_components[j].long_name;
document.getElementById('country').value = country;
}
else if (results[0].address_components[j].types[k] == "place_id"){
placeId = results[0].address_components[j].long_name;
document.getElementById('location_id').value = placeId;
}
}
}
});
//calling geocodeLatLng function
var geocoder = new google.maps.Geocoder();
var infowindow = new google.maps.InfoWindow;

});
document.getElementById("ReverseGeocode").addEventListener('click', function() {
geocodeLatLng(geocoder, map, infowindow);
});
return geocodeLatLng(geocoder, map, infowindow);
}//end of ReverseGeocode function
//redirect the map
function geocodeLatLng(geocoder, map, infowindow) {
var lat = document.getElementById("latitude").value;
var lng = document.getElementById("longitude").value;
var latlng = new google.maps.LatLng(lat, lng);
geocoder.geocode({'location': latlng}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[0]) {
map.setZoom(17);
var marker = new google.maps.Marker({
position: latlng,
center: latlng,
map: map,
draggable: true
});
infowindow.open(map, marker);
infowindow.setContent(results[0].formatted_address);
google.maps.event.addListener(marker, 'drag', function (e) {
