在Google地圖中添加多個標記

Question

我正在將google maps添加到我的網站上，並且能夠獲取我的當前位置，但是現在我想在地圖上的不同網絡位置添加標記。我該怎么做？我獲取當前位置的代碼如下：

<div id="map"></div>
<script>

  function initMap() {
    var myLatlng = {lat: 40.59726025535419, lng: 80.02503488467874};

    var map = new google.maps.Map(document.getElementById('map'),{
      center:myLatlng,


    var infoWindow = new google.maps.InfoWindow({map: map});



  // Try HTML5 geolocation.
    if (navigator.geolocation) {
      navigator.geolocation.getCurrentPosition(function(position) {
        var pos = {
          lat: position.coords.latitude,
          lng: position.coords.longitude
        };

        infoWindow.setPosition(pos);
        infoWindow.setContent('Your Location.');
        map.setCenter(pos);
      }, function() {
        handleLocationError(true, infoWindow, map.getCenter());
      });
    } else {
      // Browser doesn't support Geolocation
      handleLocationError(false, infoWindow, map.getCenter());
    }
  }

  function handleLocationError(browserHasGeolocation, infoWindow, pos) {
         infoWindow.setPosition(pos);
    infoWindow.setContent(browserHasGeolocation ?
                          'Error: The Geolocation service failed.' :
                          'Error: Your browser doesn\'t support geolocation.');
  }



</script>
<script async defer
    src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBn7svjyYLYuP-EzakUjobLmpPi41l1_hw&callback=initMap">

</script>

Answer 1

創建新的google.maps.Map（以您的情況為變量map ）后

    var marker = new google.maps.Marker({
      position: {lat: 40.59726025535419, lng: 80.02503488467874},
      map: map,
      title: 'Hello World!'
    });
    var marker2 = new google.maps.Marker({
      position: {lat: 40.59726025535419, lng: 80.02503488467874},
      map: map,
      title: 'Hello World!'
    });

來源： https ： //developers.google.com/maps/documentation/javascript/examples/marker-simple#try-it-yourself

演示-更新。 https://jsbin.com/bazoco/edit?html，控制台，輸出

嘗試使用此功能的伙伴-更新v3

  function appendMarker(map, latitude, longitude, text) {
    var pos = {lat: latitude, lng: longitude};
    var markerOption = {
      position: pos,
      map: map,
      title: text || 'Hello World!'
    };
    return new google.maps.Marker(markerOption);
  }

//Try HTML5 geolocation.
if (navigator.geolocation) {
  navigator.geolocation.getCurrentPosition(function(position) {
    var pos = {
      lat: position.coords.latitude,
      lng: position.coords.longitude
    };

    infoWindow.setPosition(pos);
    infoWindow.setContent('Your Location.');
    map.setCenter(pos);

    //could you add this code below and test ?
    var markerOp = appendMarker(map, position.coords.latitude, position.coords.longitude, 'Hello');
    var markerOp2 = appendMarker(map, position.coords.latitude + 0.005, position.coords.longitude + 0.005, 'Hello');
    //could you add this code above and test ?

  }, function() {
    handleLocationError(true, infoWindow, map.getCenter());
  });

Answer 2

您可以創建標記對象並將latlng對象傳遞給它

首先使谷歌地圖LatLng對象

var latlng = new google.maps.LatLng(latitude, longitude);

然后將此latlng對象用作標記對象中的位置

var marker = new google.maps.Marker({position: latlng,map: map,})
marker.setMap(map);

Answer 3

var myLatlng = {lat: 40.59726025535419, lng: 80.02503488467874};

var marker = new google.maps.Marker({
    position: myLatLng,
    map: map,
    title: 'Your LatLng!'
});

var marker2 = new google.maps.Marker({
    position: {lat: 40.60, lng: 80.1},
    map: map,
    title: 'Your second marker!'
});

var marker3 = new google.maps.Marker({
    position: {lat: 40.62, lng: 80.5},
    map: map,
    title: 'Your third marker!'
});
