添加UL的标记下面的地图

Add UL of Markers Underneath Map

本文关键字：地图 UL 添加      更新时间：2023-09-26

尝试在我的地图下方的半径内添加一个位置标记列表。这样做是新的函数调用回调或createMarker函数上面?

我的逻辑是使用在地图上放置标记的函数填充列表。

下面是当前代码，我的list函数的开头被注释掉了:

  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);

  1. 调用createUL函数
  2. 将位置查询的结果传递给它。
  3. 保存对标记的引用(我在gmarkers数组中这样做)
  4. 将UL中的名称链接到标记

概念验证

var geocoder;
var map;
var infowindow;
var webster = new google.maps.LatLng(43.200371, -77.498245);
var gmarkers = [];
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]);
    }
    createUL(results);
  }
}
function createMarker(place) {
  var placeLoc = place.geometry.location;
  var marker = new google.maps.Marker({
    map: map,
    position: place.geometry.location
  });
  google.maps.event.addListener(marker, 'click', function() {
    infowindow.setContent(place.name);
    infowindow.open(map, this);
  });
  gmarkers.push(marker);
}
function createUL(results) {
  var items = document.getElementById("results");
  for (var i = 0; i < results.length; i++) {
    var item = document.createElement("li");
    item.innerHTML = "<a href='javascript:google.maps.event.trigger(gmarkers[" + i + "],'"click'");'>" + results[i].name + "</a><br>";
    items.appendChild(item);
  }
}
google.maps.event.addDomListener(window, 'load', initialize);
#map-canvas {
  width: 450px;
  height: 400px;
}
<script src="http://maps.googleapis.com/maps/api/js?libraries=places"></script>
<div id="map-canvas"></div>
<div id="results"></div>
