Question

我整天都在使用Google Maps API。我可以拉上所有标记并在大约50个点上放置自定义图标。但是，我无法为标记丢弃设置交互。我做错了什么？

试试这个......（更改第34行中的标记图标路径）

<html>
<head>
    <style type="text/css">
        html {
          height: 100%
        }
        body {
          height: 100%;
          margin: 0;
          padding: 0
        }
        #map_canvas {
          height: 100%
        }
     </style>

    <script language="javascript">

   var myLatlng = new google.maps.LatLng(41.7833, 5.2167);
   var markersArray = [

Answer 2

将其放在单独的function例如addMarker()

中

function addMarker()
{
var marker = new google.maps.Marker({
map: map,
position: point,
icon: '1364428325_golf.png',
animation: google.maps.Animation.DROP,
shadow: icon.shadow
});
}

然后在addMarker()函数

中调用setTimeout()

在你的代码中我看不到你在setTimeOut（）中描述的方法标记（）

您随时可以访问https://gist.github.com/donpaul120/dc97f4ec4785521b3a66并实施它。
