TypeError: google.maps.Markers不是构造函数

Question

我将使用marker cluster数据使用info window创建json。

但是google.maps.Markers is not a constructor error.Though标记集群没有显示

这是我的密码：

var map = new google.maps.Map(document.getElementById('map'), {
            zoom: 5,
            center: {"lat": 39.317779, "lng": -101.459656},
            mapTypeId: 'roadmap',
          });
          map.setTilt(45);

          for(var i=0;i<locations.length;i++){
            var data=locations[i];
            var mylatlng=new google.maps.LatLng(locations.lat,locations.lng);
            var markers = new google.maps.Markers({
              position:mylatlng,
              map:map

            });
            (function(marker,data){
              google.maps.event.addListener(marker,'click',function(e){
                infowindow.setContent(data.code +
                          '<br/>' + data.PIN +
                          '<br/><b>STOCKNO:</b> ' + data.No +
                          '<br/><b>STATUS:</b> ' + data.Status);
                infowindow.open(map, marker);
              })
            })(marker,data);
            }

          var markerCluster = new MarkerClusterer(map, markers,
                  {imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'});

}

$(document).ready(function(){
  initialization() 
});

function initialization() {
        
  var map = new google.maps.Map(document.getElementById('map'), {

  map.setTilt(45);

  for(var i=0;i<locations.length;i++){
    var data=locations[i];
    var marker = new google.maps.Marker({
      position: {lat: data.lat, lng: data.lng},
      map : map

    attachSecretMessage(marker, i);

  }

  function attachSecretMessage(marker, i) {
    var data = locations[i];

      secretMessage = `${data.code}

      marker.addListener('click', function() {

另外，我已经更新了一些位置，看看这个。为了找到集群，您需要放大。

希望这能解决你的问题。

你做了个小错误。当new google.maps.Markers应该是new google.maps.Marker时，您就有了它(注意末尾缺少"s“)。
