为动态创建的 google-map 标记创建事件侦听器

Question

我正在尝试创建一个要与 excel 和 vba 集成的页面。 .我想在单击标记时将事件监听器添加到标记。我几乎无法为单个标记创建 "click listener"，但我无法为使用循环动态创建的多个标记创建它。

单击标记时，我希望街景更新到新单击标记的位置。

非常感谢任何建议。谢谢。

这就是我所拥有的（来自这里和那里）。

Answer 1

// 将此代码包含到您的循环中

var infowindow = new google.maps.InfoWindow({
    content: 'info content'
});
google.maps.event.addListener(marker, 'click', function() {
    infowindow.open(map,marker);
});

Answer 2

在你的函数中 (function(data){....})(data); 因为你使用了标记数组。

function addMarker(data) {
  (function(data){   <<-- New line added 
  // Create the marker
  var marker = new google.maps.Marker({
    position: new google.maps.LatLng(data.lat, data.lng),
    map: map,
    label: labels[labelIndex++ % labels.length],
    title: data.name
  });

  google.maps.event.addListener(marker, 'click', function(){// <<---- New line added
       // Code event listener .... 
  });// <<---- New line added

  })(data); // <<---- New line added
}

Answer 3

保留对全景图的引用：

// Set the initial Street View camera to the center of the map
new google.maps.StreetViewPanorama(document.getElementById('pano'), panoramaOptions);

应该是：

// Set the initial Street View camera to the center of the map
panorama = new google.maps.StreetViewPanorama(document.getElementById('pano'), panoramaOptions);

更改 panorama 在 marker 点击侦听器中的位置。

google.maps.event.addListener(marker,'click', function(e) {
   pano.setPosition(marker.getPosition());
});

代码片段：

var labels = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'; //me
var labelIndex = 0; //me
var map;
var panorama;

//this will be created from server side

var markers = [{
  lat: 39.976784,
  lng: -75.234347,
  name: "marker 1"

  lat: 39.977043,

}, {

  lng: -75.233682,
  name: "marker 4"
}];
var myLatlng = new google.maps.LatLng(markers[0].lat, markers[0].lng);


function initialize() {
  //var sv = new google.maps.StreetViewService();
  panorama = new google.maps.StreetViewPanorama(document.getElementById('pano'));


  var mapOptions = {
    zoom: 16,

  pano = new google.maps.StreetViewPanorama(document.getElementById('pano'),

  //this is the loop that will creat the marker
  for (var index in markers) addMarker(markers[index]);

  function addMarker(data) {

    var marker = new google.maps.Marker({
