在地图下添加标记的UL

Question

尝试在地图下方的半径范围内添加地点标记列表。这样做的是新函数调用上面的回调或createMarker函数吗？

我的逻辑是使用将标记放在地图上的函数填充列表。

这是当前代码，我的列表函数的开头已注释掉：

  var geocoder;
var map;
var infowindow;
var webster = new google.maps.LatLng(43.200371, -77.498245);

function initialize() {  
  var latlng = new google.maps.LatLng(-34.397, 150.644);
  var mapOptions = {
    zoom: 8,
    center: latlng
  }
  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
codeAddress();
var request = {
    location: webster,
    radius: 50000,
    types: ['store']
  };
  infowindow = new google.maps.InfoWindow();
  var service = new google.maps.places.PlacesService(map);
  service.nearbySearch(request, callback);
}

function codeAddress() {
  geocoder = new google.maps.Geocoder();  
  var address = '2450 Empire Blvd, Webster, NY 14580 US';   
  geocoder.geocode( { 'address': address}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      map.setCenter(results[0].geometry.location);
      var marker = new google.maps.Marker({
          map: map,
          position: results[0].geometry.location
      });
    } else {
      alert('Geocode was not successful for the following reason: ' + status);
    }
  });
}

function callback(results, status) {
  if (status == google.maps.places.PlacesServiceStatus.OK) {
    for (var i = 0; i < results.length; i++) {
      createMarker(results[i]);
    }
  }
}

function createMarker(place) {
  var placeLoc = place.geometry.location;
  var marker = new google.maps.Marker({
    map: map,
    position: place.geometry.location
  });

function createUL(){
    var items = document.getElementById("results");

    for (var i = 0; i < results.length; i++ ) {
        var item = document.createElement("li");
        item.innerHTML = results[i];
        items.appendChild(item);
    }

}

  google.maps.event.addListener(marker, 'click', function() {
    infowindow.setContent(place.name);
    infowindow.open(map, this);
  });
}


google.maps.event.addDomListener(window, 'load', initialize);

Answer 1

1. 调用createUL函数。
2. 将places查询中的结果传递给它。
3. 保存对标记的引用（我在gmarkers数组中完成）
4. 将UL中的名称链接到标记
