必须有一种方法可以将侦听器添加到所有标记，目前我正在使用感觉非常错误的循环为每个标记添加侦听器...
感觉不对：
google.maps.event.addListener(unique_marker_id, 'click', function(){
//do something with this marker...
});

在Marker 和MarkerWithLabel 的情况下，您不妨使用this 关键字来引用事件处理程序所附加到的对象：
google.maps.event.addListener(marker, 'click', function () {
// do something with this marker ...
this.setTitle('I am clicked');
});
this 这里指的是特定的标记对象。
【讨论】：
您需要将侦听器添加到每个标记，但您可以通过例如定义一个函数，如
function createMarker(pos, t) {
var marker = new google.maps.Marker({
position: pos,
map: m, // google.maps.Map
title: t
});
google.maps.event.addListener(marker, 'click', function() {
alert("I am marker " + marker.title);
});
return marker;
}
并适当地调用它：
var m1 = createMarker(new google.maps.LatLng(...), "m1");
var m2 = createMarker(new google.maps.LatLng(...), "m2");
或在循环中等
【讨论】：
如果您使用的是 GoogleMaps v3.16 或更高版本，您可以将事件处理程序添加到整个 map.data 层。
var map = new google.maps.Map(document.getElementById("map-canvas"), options);
map.data.loadGeoJson('http://yourserver.com/path/to/geojson.json');
map.data.addListener('click', function(e) {
// this - instance of the layer object, in this case - map.data
// e.feature - instance of the feature object that initiated the event
// e.latLng - the position of the event
});

我设法使用 FusionTablesLayer 做到了这一点。正确设置所有内容需要一些工作，但一旦完成，即使有数千个标记，它也非常快。
您基本上是在 Google Docs 中创建一个公共表并从您的网页中查询它。该地图是在 Google 的服务器上预先生成的，这就是它表现如此出色的原因。

我设法在这里得到了答案： Google Maps and Their Markers
这里有一个演示： http://jsfiddle.net/salman/bhSmf/

这个最简单的方法是这样的：
google.maps.event.addListener(marker, 'click', function() {
var marker = this;
alert("Tite for this marker is:" + this.title);
});

为那些希望添加自定义标签等的搜索者扩展 Jiri 答案 purley。本着 Jiri 帖子的精神，简写版本：
var m1 = createMarker({lat: -25.363, lng: 131.044}, "m1", "<div id=\"content\"><div id=\"siteNotice\"></div> <h1 id=\"firstHeading\" class=\"firstHeading\">m1</h1> <div id=\"bodyContent\">Some info</div> </div>");
function createMarker(pos, t, d) {
var marker = new google.maps.Marker({
position: pos,
map: map,
title: t
});
google.maps.event.addListener(marker,"click", function() {
alert("I am marker " + marker.title);
new google.maps.InfoWindow({ content: d }).open(map, marker);
});
return marker;
}
删除警报，只是在那里显示动作等。与 Jiri 的信息一样，您可以添加 m2、m3 等。我认为这只是完成了一些事情。

/* Note: I have a set of data, and it is named by the variable data.

*/
//Here I get the length of the data
var dataLength = data.length;
//Then I iterate through all my pieces of data here
//NOTICE THAT THE KEYWORD let IS SO IMPORTANT HERE
for(let markerIterator = 0; markerIterator < dataLength; markerIterator++) {

google.maps.event.addListener(marker, 'click', function () {
/* This will spit out the unique markerIterator value for each marker when

console.log(markerIterator);
// Use the keyword this to refer to each unique marker, for example:
map.setCenter(this.getPosition());
});

我所做的是，在地图上添加新的marker 并将其推入markers = [] 数组之前，我只需将侦听器添加到它marker.addListener('click', () => { // Do Something here});
完整代码：
// Adds a marker to the map and push to the array.
function addMarker(location) {
var marker = new google.maps.Marker({
position: location,
icon: {
url: "http://maps.google.com/mapfiles/ms/icons/blue-dot.png"
},
animation: google.maps.Animation.DROP,
map: map
});
marker.addListener("click",
() => {
console.log("Marker Click Event Fired!");
});
markers.push(marker);
}

我真的很难找到满足我需求的具体答案。但是这个现在和任何地方都在为我工作！ 问候！ :)

你可以这样做：
function setMarkers(map, locations) {
var image = ['circle_orange.png','circle_blue .png'];
for (var i = 0; i < locations.length; i++) {
var stations = locations[i];
var myLatLng = new google.maps.LatLng(stations[1], stations[2]);
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: image[stations[3]],
title: stations[0],
zIndex: stations[3],
optimized: false
});
var infowindow = new google.maps.InfoWindow({
content: "No data available"
});
google.maps.event.addListener(marker, 'mouseover', function() {
infowindow.setContent("We can include any station information, for example: Lat/Long: "+ stations[1]+" , "+stations[2]);
infowindow.open(map, this);
});
}
}
