javascript - Array.prototype.map()方法添加信息窗口

Question

我已按照教程创建集群谷歌地图，但我无法使信息窗口正常工作？我可以让它工作，否则...只是不使用 Array.prototype.map() 方法...有什么帮助吗？

    var locations = []
    var data
    var markerData

    $('.map').each(function (get){ //gather data from html and store
      data = $(this).data();
      markerData = ([data.txt, data.lat, data.lng])
      locations.push(markerData);
    });

    function initMap() {

      var infowindow = new google.maps.InfoWindow(); /* SINGLE */
      var map = new google.maps.Map(document.getElementById('map'), {
        zoom: 14,
        center: {lat: 50.07821, lng: 8.23976}
      });

      // Create an array of alphabetical characters used to label the markers.
      var labels = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';

      // Add some markers to the map.
      // Note: The code uses the JavaScript Array.prototype.map() method to
      // create an array of markers based on a given "locations" array.
      // The map() method here has nothing to do with the Google Maps API.
      var markers = locations.map(function(loc, i) {
        return new google.maps.Marker({
          position: new google.maps.LatLng(loc[1], loc[2]),
          animation: google.maps.Animation.DROP,
          label: labels[i % labels.length]

        });

      });

      // Add a marker clusterer to manage the markers.
      var markerCluster = new MarkerClusterer(map, markers,
                                              {imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'});
      google.maps.event.addListener(markers, 'click', function(loc){
        console.log('hit')
            infowindow.close(); // Close previously opened infowindow
            infowindow.setContent( "<div id='infowindow'>"+ loc[0] +"</div>");
            infowindow.open(map, markers);
        });

    }

您的标记点击监听器位于错误的位置。它只能监听一个标记:

var markers = locations.map(function(loc, i) {
  var marker = new google.maps.Marker({
    position: new google.maps.LatLng(loc[1], loc[2]),
    animation: google.maps.Animation.DROP,
    label: labels[i % labels.length]
  });
  google.maps.event.addListener(marker, 'click', (function(loc) {
  return function(evt) {
    infowindow.close(); // Close previously opened infowindow
    infowindow.setContent("<div id='infowindow'>" + loc[0] + "</div>");
    infowindow.open(map, marker);
  }}(loc)));
  return marker
});
