Question

我正在尝试在地图上添加点击监听器，这是我的代码

更新

<!DOCTYPE html>
<html>
  <head>
  <script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
</head>
<style>
    #map-canvas{
 width:500px; 
 height:500px;
}
</style>
<script  type="text/javascript">
    var cityPoints = {
        center: new google.maps.LatLng(41.878113, -87.629798),
        id: 0,
        addr: 'avenue0',
        magnitude: 100000
    };

    var cityCircle;
    var infoWindow = new google.maps.InfoWindow({
        content: "<div>Hello! World</div>",
        maxWidth: 500
    });


  function initialize() {
 var mapOptions = {
     zoom: 4,
     center: new google.maps.LatLng(31.2330555556, 72.3330555556),
     mapTypeId: google.maps.MapTypeId.TERRAIN
 };

  var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

  var populationOptions = {
      strokeColor: "#FF0000",
      strokeOpacity: 1,
      strokeWeight: 1,
      clickable: true,
      fillOpacity: 0,
      map: map,
      center: new google.maps.LatLng(31.231867, 72.33336),
      radius: 200000
  };

  cityCircle = new google.maps.Circle(populationOptions);


    google.maps.event.addListener(cityCircle, 'click', function (ev) {
        infoWindow.setPosition(ev.latLng);
        infoWindow.open(map);
    });
}
initialize();
</script>
<body>
    <div id="map-canvas"></div>
</body>
</html>

但是这段代码对我不起作用因为当我点击circle.Plz时，我的窗口没有打开。任何人告诉我在我的代码中缺少了什么.Plz帮助

Answer 1

也许这个google.maps.event.addDomListener(window, 'load', initialize);是缺失的。这是一个有效的例子

我把半径变大了一点。

this有效吗？

我把它全部放在一个文件中，这样你就可以复制并粘贴它了。

在圆圈上添加点击监听器不起作用
