我使用 KML 文件只是为了掩盖世界其他地方，只显示我的国家，我已经添加了多个标记，现在我想在单击标记时添加信息框，但它不起作用。

这是我的 KML File

Answer 1

这与您的 KML 掩码无关。您有一个 CSS 设置破坏了标记点击侦听器 (zoom: 0.8)，将其移除，信息框会在点击时出现（尽管它们存在内容和格式问题）。

您还需要在标记点击事件函数中关闭函数（或者您只在最后一个标记上获得信息框）：

    google.maps.event.addListener(marker, "click", (function(marker,data) {
      return function(e) {
        infoBox.setContent(data.description);
        infoBox.open(map, marker);
    }})(marker, data));

工作代码片段（没有掩码）：

function initMap() {
  var myLatLng = {
    lat: 19.0760,
    lng: 72.8777
  };
  var map = new google.maps.Map(document.getElementById('map-canvas'), {
    center: new google.maps.LatLng(22.4913, 78.9000),
    zoom: 5,
    mapTypeId: google.maps.MapTypeId.ROADMAP,
    disableDefaultUI: true,
  });
  var geocoder = new google.maps.Geocoder();
  /* var geoXml = new geoXML3.parser({
      map: map, 
      zoom: false,
      suppressInfoWindows: true, 
      preserveViewport: true       
  }); */
  // geoXml.parse('India_KML.kml');     
  var json = [{
    "title": "Dive goa",
    "lat": 11.372230617418888,
    "lng": 76.00253776872557,

    var marker = new google.maps.Marker({
      position: latLng,

    });
    google.maps.event.addListener(marker, "click", (function(marker, data) {
